o INTRODUCTION This report c6ntains results of tests conducted on PIDG PVT 2 radiation resistant terminals.
Testing was conducted to evaluate the products performance when subjected to bending of terminal tongues of 60o and 900 and a twist of the tongue approximately 45 These variations were subjected to Millivolt drop followed by vibration and a final millivolt drop measurement per MIL-T-79286.
Testing was conducted in AMP Laboratories during the month of March, 1985 U0lVATON' TEST SPECIMEN DESCRIPTION The following Terminals and quantities were tested.

TEST METHODS Voltage Dron.
Each terminal was measured for voltage drop by energizing with 55 Emperes with DC current and probing at the intersection of the tongue and wire barrel and a point on the wire 6" back from the terminal probe point.
Vibration.
Terminals were rigidly mounted to and not more than 1 inch above the vibrating platform by their normal mounting means.
The test terminals were so mounted that the junction of the other end of the test sample was secured to a stable support 12 inches external to the vibrating table with all l
slack or tension removed from the wire.
The specimens were vibrated in accordance with method 201 of MIL-STD-202 for 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> on each of two axes i
mutually perpendicular to each other and to the axis of the wire.

- Sample broke after 9.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> in the first plane of Vibration.
The sample was bent 600 and broke in the transition area between the tongue and wire barrel.
All other samples displayed no signs of physical damage.
APPENDIX A The sample which broke off after 9 0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> in the first plane of vibration apparently was mounted improperly as all of the remaining samples of group 1 and the other two groups went the full 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> of both planes without displaying any signs of physical damage.
Based on the information acquired from this test, we can say that any static application, with little or no vibration present, should see no detrimental results through bending of the togue on a one time basis to 600 or 9n0 The same can be said of the twisted tongue to h50 Even if the terminals were to face moderate vibration such as that set up by heavy equipment running, we feel that the testing proves that the terminations will withstand such a condition without any detrimental affects.

,tt SUMMAltY OF DISCUSSION, DECl$lONS AND COMMITMENT 5.
W. I. Vogelsang discussed the AMP memo dated September 2, 1981*in which Mr.
B. Eister.had indicated a 60 bend without reannealing was acceptable. It was discussed that with some suppliers at CPSES (GE Co in particular) that it was necessary to bend terminals for internal wiring up to 120. It was pointed out that for these cases, the application was for short jumpers (nonnally under 18 inches), and as such, the full mechanical strength of the connector was not required.
Floyd Renshaw responded that the current AMP position was that the subject teiminals could be bent one time to a 90* bend or two times to a 45* tend.
However, this does not pr.eclude bending the terminals up to 120*. In this case, an Engineering evaluation for the specific type of application could be done by the product user. Items that should be taken into account are as follows:
a) length of wire to be supported by the terminal b) the susceptibility to vibrations c) once installed if it is contemplated rebending these tenninals, they should be discarded and replaced by a new terminal.
Floyd Renshaw also advised that while a terminal bent more that 90* to 120* would not retain its full mechanical strength it would mainatin its electrical characteristics.

REWORK REPAIR USE AS IS SCRAP Thg AMP current pgsition (CPPA 38241) is that their tenninals may be bent one time to 90 and up to 120 with an Engineering evaluation.
In this case, General Electric Company's application is for short jumpers in the MCC draw-out units.
These short jumpers are such that they are not susceptible to vibra-tions.
As such the terminals full mechanical strength is not required.
Additionally, this installation configuration is the same as that qualified by General Electric Company in their IEEE 323 qualification program.
Engineering has determined that the terminals bent to 120 do not pose an equipment serviceability problem and may be used as is.

Compartment being inspected was 7C of CP2-EPMCEB-03. After dis-covering this situation compartments 7F and 6F also disp. lay same con-figuration, and in some cases barrel of lug has been bent over retaining screw head, indicating the fact that it is very doubtful that reannealing process as required by amp has ever occurred at General Electric when equipment was manufactured.
This is also in violation of amp procedures and appears to be a generic problem in all motor control centers with starter, thermal overload relay combination arrangements.

W. I. Vogelsang discussed the AMP memo dated September 2,1981'in which Mr.
B. Eister. had indicated a 60* bend without reannealing was acceptable. It was discussed that with some. suppliers at CPSES (GE Co in particular) that it was necessary to bend tenninals for internal wiring up to 120. It was pointed out that for these cases, the application was for short jumpers (nonnally under 18 inches), and as such, the full mechanical strength of the connector was not required.
l Floyd Renshaw responded that the current AMP position was that the subject teiminals could be bent one time to a 90 bend or two times to a 45* bend.
l-However, this does not pr.eclude. bending the terminals up to 120*. In this case, an Engineering evaluation for the specific type of application could be done by the product user. Items that should be taken into account are as follows:
a) length of wire to be supported by the terminal the susceptibility to vibrations b) c)
once installed if it is contemplated rebending these terminals,
~
they should be discarded and replaced by a new terminal.
Floyd Renshaw also advised thati while a terminal bent more that 90* to 120* would not retain its full mechanical strength it would mainatin its

INTRODUCTION This report cbntains results of tests conducted on PIDG PVF2 radiation resistant terminals.
Testing was conducted to evaluate the products 0 and 900 and a performance when subjected to bending of terminal tongues of 60 twist of the tongue approximately 45 These variations were subjected to Millivolt drop followed by vibration and a final millivolt drop measurement per MIL-T-79286.
Testing was conducted in AMP Laboratories during the month of March, 1985 M 0 M E 0'v 1

TEST SCHEDULE Terminals were subjected to the following test in the sequence specified.
Test Groue and Seauence Test Groun 1 Group 2 G roun 1 Voltare Droe 1-3 1-4 1-9 Vibration 2

TEST METHODS Voltare Droo.
Each' terminal was measured for voltage drop by energizing with 55 amperes with DC current and probing at the intersection of the tongue and wire barrel and a point on the wire 6" back from the terminal probe point.
Vibration.
Terminals were rigidly mounted to and not more than 1 inch above the vibrating platform by their normal mounting means.
The test terminals were so mounted that the Junction of the other end of the test sample was secured to a stable rapport 12 inches external to the vibrating table with all slack or tension removed from the wire.
The specimens were vibrated in accordance with method 201 of MIL-STD-202 for 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> on each of two axes mutually perpendicular to each other and to the axis of the wire.

- Sample broke after 9 0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> in the first plane of Vibration.
The sample was bent 600 and broke in the transition area between the tengue and wire barrel.
All other samples displayed no signs of physical damage.
APPENDIX A The sample which broke off after 9 0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> in the first plane of vibration apparently was mounted improperly as all of the remaining samples of group 1 and the other two groups went the full 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> of both planes without displaying any signs of physical damage.
Based on the information acquired from this test, we can say that any static application, with little or no vibration present, should see no detrimental results through bending of the togue on a one time basis to 600 or 900 The same can be said of the twisted tongue to 450 Even if the terminals were to face moderate vibration such as that set up by heavy equipment running, we feel that the testing proves that the terminations will withstand such a condition without any detrimental affects, i

TEST METHODS Voltare Droo.
Each terminal was measured for voltage crop by energi:ing with 55 amperes with DC current and probing at the intersection of the tongue and wire barrel and a point on the wire 6" back from the terminal probe point.
Vibration.
Terminals were rigidly mounted to and not more than 1 inch above the vibrating platform by their normal mounting means.
The test terminals were so mounted that the junction of the other end of the test sample was secured to a stable support 12 inches external to the vibrating table with all slack or tension removed from the wire.
The specimens were vibrated in accordance with method 201 of MIL-STD-202 for 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> on each of two axes mutually perpendicular to each other and to the axis of the wire.

- Sample broke after 9 0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> in the first plane of Vibration.
The sample was bent 600 and broke in the transition area between the tongue and wire barrel.
All other samples displayed no signs of physical damage.
APPENDIX A The sample which broke off after 9.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> in the first plane of vibration apparently was mounted improperly as all of the remaining samples of group 1 and the other tvo groups went the full 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> of both planes without displaying any signs of physical damage.
Based on the information acquired from this test, we can say that any static application with little or no vibration present, should see no detrimental results through bending of the togue on a one time basis to 600 or 900 The same can be said of the twisted tongue to 450 Even if the terminals were to face moderate vibration such as that set up by neavy equipment running, we feel that tne testing proves that the terminations vill withstand such a l
condition without any detrimental affects.

\\_ f SUfA7AARY CF DISCUSSION. DECISIONS AND COMA 4 TW_~%*IS.
W. I. Vogelsang discussed the AMP memo dated September 2,1981'in which Mr.
B. Eister. had indicated a 60* bend without reannealing was acceptable. It was discussed that with some suppliers at CPSES (GE Co in particular) that it was necessary to bend terminals for internal wiring up to 120. It was pointed out that for these cases, the application was for short jumpers (normally under 18 inches), and as such, the full mechanical strength of the connector was not required.
Floyd Renshaw responded that the current AMP position was that the subject teiminals could be bent one time to a 90 bend or two times to a 45 bend.
However, this does not pr.eclude bending the terminals up to 120. In this case, an Engineering evaluation for the specific type of application could be done by the product user. Items that should be taken into account are as follows:
a) length of wire t'6 be supported by the terminal b) the susceptibility to vibrations c) once installed if it is contemplated rebending these terminals,
~
they should be discarded and replaced by a new terminal.
Floyd Renshaw also advised that while a terminal bent more that 90 to 120 would not retain its full mechanical strength it would mainatin its electrical characteristics.,

SUMMARY
CF DISCUSSION, DECISIONS AND CCMMITASINIS.
W. I. Vogelsang discussed the AMP memo dated September 2,1981 in which Mr.
B. Eister had indicated a 60 bend without reannealing was acceptable. It was discussed that with some suppliers at CPSES (GE Co in particular) that it was necessary to bend terminals for internal wiring up to 120. It was pointed out that for these cases, the application was for short jumpers (normally under 18 inches), and as such, the full mechanical strength of the connector was not required.
Floyd Renshaw responded that the current AMP position was that the subject teiminals could be bent one time to a 90" bend or two times to a 45* bend.
~
s However, this does not pr.eclude bending the terminals up to 120*.' In this case, an Engineering evaluation for the specific type of application could be done by the product user. Items that should be taken into account are as follows:
a) length of wire t'd be supported by the terminal b) the susceptibility to vibrations c) once installed if it is contemplated rebending these tenninals, they should be discarded and replaced by a new terminal.
Floyd Renshaw also advised that while a terminal bent more that 90 to 120* would not retain its full mechanical strength it would mainatin its electrical characteristics.

INTRODUCTION This report c6ntains results of tests conducted on PIDG PVT 2 radiation resistant terminals.
Testing was conducted to evaluate the products performance when subjected to bending of terminal tongues of 600 and 900 and a twist of the tongue approximately 45 These variations were subjected to Millivolt drop followed by vibration and a final millivolt drop measurement per MIL-T-79286.
Testing was conducted in AMP Laboratories during the month of March, 1985 1IFORMATi0h TEST SPECIMEN DESCRIPTION The following Terminals and quantities were tested.

TES*/ SCHEDULE Terminals were subjected to the following test in the sequence specified.
Test Groue and Sequence Test Groun 1 Groun 2 Groun 1 Voltare Droo 1-1 1-4 1-9 Vibration 2

TEST METHODS Voltare Droe, Each terminal was measured for voltage drop by energizing with SS amperes with DC current and probing at the intersection of the tongue and wire barrel and a point on the wire 6" back from the terminal probe point.
Vibration.
Terminals were rigidly mounted to and not more than 1 inch above the vibrating platform by their normal mounting means.
The test terminals were so mounted that the junction of the other end of the test sample was secured to a stable support 12 inches external to the vibrating table with all slack or tension removed from the wire.
The specimens were vibrated in accordance with method 201 of MIL-STD-202 for 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> on each of two axes mutually perpendicular to each other and to the axis of the wire.

The sample was bent 600 and broke in the transition area between the tongue and wire barrel.
"-All other samples displayed no signs of physical damage.
APPENDIX A The sample which broke o'ff after 9 0 hout-in the first plane of vibration apparently was mounted improperly as all c. the remaining samples of group 1 and the other two groups went the full 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> of both planes without j
displaying any signs of physical damage.
Based on the information acquired from this test, we can say that any static application, with little or no vibration present, should see no detrimental results through bending of the togue on a one time basis to 600 or 900 The same can be said of the twisted tongue to 450 Even if the terminals were to face moderate vibration such as that set up by heavy equipment running, we feel that the testing proves that the terminations will withstand such a condition without any detrimental affects.

The sample was bent 600 and broke in the transition area between the t Q and wire barrel.
All other samples displayed no signs of physical damage.
APPENDIX A The sample which broke off after 9 0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> in the first plane of vibration apparently was mounted improperly as all of the remaining samples of group 1 and the other two groups went the full 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> of both planes without displaying any signs of physical damage.
Based on the information acquired from this test, we can say th'at any static application, with little or no vibration present, should see no detrimental results through bending of the togue on a one time basis to 600 or 900 The same can be said of the twisted tongue to 45 Even if the terminals were to face moderate vibration such as that set up by heavy equipment running, we feel that the testing proves that the terminations will withstand such a condition without any detrimental affects.

SUMMARY
oF DISCUS $10N, OEctSIONS At4D COMMrT#1N15.
W. I. Vogelsang discussed the AMP memo dated September 2,1981'in which Mr.
B. Eister. had indicated a 60* bend without reannealing was acceptable. It was discussed that with some suppliers at CPSES (GE Co in particular) that it was necessary to bend terminals for internal wiring up to 120. It was pointed out that for these cases, the application was for short jumpers (normally under 18 inches), and as such, the full mechanical strength of the connector was not required.
Floyd Renshaw responded that the current AMP position was that the subject teiminals could be bent one time to a 90* bend or two times to a 45* bend.
However, this does.not pr.eclude bending the terminals up to 120. In this case, an Engineering evaluation for the specific type of application could be done by the product user. Items that should be taken into account are as follows:
a) length of wire t'6 be supported by the terminal b) the susceptibility to vibrations c) once installed if it is contemplated rebending these terminals,
~
they should be discarded and replaced by a new terminal.
Floyd Renshaw also advised that while a terminal bent more that 90 to 120* would not retain its full mechanical strength it would mainatin its electrical characteristics.,,

sU.WAARY CF DISCUS $1CN, DECISIONS AND CoMMITENs W. I. Vogelsang discussed the AMP memo dated September 2,1981*in which Mr.
B. Eister had indicated a 60 bend without reannealing was acceptable. It was discussed that with some suppliers at CPSES (GE Co in particular) that it was necessary to bend terminals for internal wiring up to 120. It was pointed out that for these cases, the application was for short jumpers (normally under 18 inches), and as such, the full mechanical strength of the connector was not required.
Floyd Renshaw responded that the current AMP position was that the subject teiminals could be bent one time to a 90 'uend or two times to a 45 bend.
However, this does.not pr.eclude bending the terminals up to 120. In this case, an Engineering evaluation for the specific type of application could be done by the product user. Items that should be taken into account are as follows:
a) length of wire t'd be supported by the terminal b) the susceptibility to vibrations c) once installed if it is contemplated rebending these terminals, they should be discarded and replaced by a new terminal.
Floyd Renshaw also advised that while a terminal bent more that 90 to 120 would not retain its full mechanical strength it would mainatin its electrical characteristics.

TEST METHODS Voltare Dron.
Each *,erminal was measured for voltage drop by energizing with 95 amperes with DC current and probing at the intersection of the tongue and wire barrel and a point on the wire 6" back from the terminal probe point.
Vibratien.
Terminals were rigidly mounted to and not more than 1 inch above the vibrating platform by their normal mounting means.
The test terminals were so mounted that the junction of the other end of the test sample was l
secured to a stable support 12 inches external to the vibrating table with all slack or tension removed from the wire.
The specimens were vibrated in accordance with method 201 of MIL-STD-202 for 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> on each of two axes l
mutually perpendicular to each other and to the axis of the wire.

- Sample broke after 9 0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> in the first plane of Vibration.
The sample was bent 600 and broke in the transition area between the tongue and wire barrel.
All other samples displayed no signs of physical damage.
APPENDIX A The sample which broNe off after 9 0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> in the first plane of vibration apparently was mounted improperly as all of the remaining samples of group 1 and the other tuc groups went the full 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> of both planes without displaying any signs of physical damage.
Based on the information acquired from this test, we can say that any static application, with little or no vibration present, should see no detrimental results through bending of the togue on a one time basis to 600 or 900 The same can be said of the twisted tongue to 45 Even if the terminals were to face moderate vibration such as that set up by heavy equipment running, we feel that the testing proves that the terminations will withstand such a condition without any detrimental affects.

The sample was bent 600 and broke in the transition area between the tongue and wire barrel.
All other samples displayed no signs of physical damage.
APPENDIX A The sample which broke off after 9 0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> in the first plane of vibration apparently was mounted improperly as all of the remaining samples of group 1 and the other two groups went the full 18 nours of both planes without' displaying any signs of physical damage.
Based on the information acquired from this test, we can say that any static application, with little or no vibration present, should see no detrimental results through bending of the togue on a one time basis to 600 or 900 The same can be said of the twisted tongue to 450 Even if the terminals were to face moderate vibration such as that set up by heavy equipment running, we feel that the testing proves that the terminstions will withstand such a condition without any detrimental affects.

SUfA1AARY CF DISCUSSION, DEclSICNS AND COMMITM A
A W. I. Vogelsang discussed the AMP memo dated September 2,1981*in which Mr.
B. Eister had indicated a 60 bend without reannealing was acceptable. It was discussed that with some suppliers at CPSES (GE Co in particular) that it was necessary to bend terminals for internal wiring up to 120. It was pointed out that for these cases, the application was for short jumpers (normally under 18 inches), and as such, the full mechanical strength of the connector was not required.
Floyd Renshaw responded that the current AMP position was that the subject teiminals could be bent one time to a 90 bend or two times to a 45 bend.
However, this does not pr.eclude bending the terminals up to 120. In this case, an Engineering evaluation for the specific type of application could be done by the product user. Items that should be taken into account are as follows:
a) length of wire t'd be supported by the terminal the susceptibility to vibrations b)c) once installed if it is contemplated rebending these terminals, they should be discarded and replaced by a new terminal.
Floyd Renshaw also advised that while a terminal bent more that 90 to would not retain its full mechanical strength it would mainatin its 120 electrical characteristics....

W. I. Vogelsang discussed the AMP memo dated September 2, 1981*in which Mr.
B. Eister had indicated a 60* bend without reannealing was acceptable. It was discussed that with some suppliers at CPSES (GE Co in particular) that it was necessary to bend terminals for internal wiring up to 120*. It was l
pointed out that for these cases, the application was for short jumpers (normally under 18 inches), and as such, the full mechani. cal strength of the connector was not required.
Floyd Renshaw responded that the current AMP position was that the subject teiminals could be bent one time to a 90* bend or two times to a 45* bend.
However, this does not pr.eclude bending the terminals up to 120*. In this case, an Engineering evaluation for the s)ecific type of application could be done by the product user. Items that s1ould be taken into account are as follows:
a) length of wire to be supported by the terminal b) the susceptibility to vibrations c) once installed if it is contemplated rebending these tenninals,
~
they should be discarded and replaced by a new terminal.
Floyd Renshaw also advised that while a terminal bent more that 90* to 120* would not retain its full mechanical strength it would mainatin its electrical characteristics.

Testing was conducted to evaluate the products 0 and 900 and a performance when subjected to bending of terminal tongues of 60 twist of the tongue approximately 45 These variations were subjected to Millivolt drop followed by vibration and a final millivolt drop====~----t per MIL-T-79286. Testing was conducted in AMP Laborator r<o i th TEST P I EN ESCRIPTION -The following Terminals and quantities were tested. 3 ) RV Quantities ner Test Grout Terminal Part No. Wire size Group 1 Group 2 Group 1 53425-1 10 AWG 4 d 600 Bends 4 @ 900 Bends 4 @ 450 Twists Wire used for testing was per MIL-W-5086 with tin plated copper strands. TEST SCHEDULE Terminals were subjected to the following test in the sequence specified. Test Groue and Sequence Test Groue 1 Grouc 2 Grout 1 2 tare Droo 1-1 1-4 1-1 1 V Vibration 2 2 2 TEST METHODS Voltare Droo. Each terminal was measured for voltage crop by energi::ing with 55 amperes with DC current and probing at the intersection of the tongue and wire barrel and a point on the wire 6" back from the terminal probe point. Vibration. Terminals were rigidly mounted to and not more than 1 inch above the vibrating platform by their normal mounting means. The test terminals were so mounted that the junction of the other end of the test sample was secured to a stable support 12 inches external to the vibrating table with all slack or tension removed from the wire. The specimens were vibrated in accordance with method 201 of MIL-STD-202 for 18 hours on each of two axes mutually perpendicular to each other and to the axis of the wire. 1-

- Sample broke after 9 0 hours in the first plane of Vibration.
The sample was bent 600 and broke in the transition area between the tongue and wire barrel. All other samples displayed no signs of physical damage. APPENDIX A The sample which broke off after 9 0 hours in the first plane of vibration apparently was mounted improperly as all of the remaining samples of group 1 and the other two groups went the full 18 hours of both planes without displaying any signs of physical damage. Based on the information acquired from this test, we can say that any static appl.Leation, with little or no vibration present, should see no detrimental results through bending of the togue on a one time basis to 600 or 900 The same csn be said of the twisted tongue to 450 Even if the terminals were to l face moderate vibration such as that set up by heavy equipment running, we i feel that the testing proves that the terminations will withstand such a condition without any detrimental affects. \\g0%\\ Y COOT e M M

W. I. Vogelsang discussed the AMP memo dated September 2,1981*in which Mr. B. Eister had indicated a 60* bend without reannealing was acceptable. It was discussed that with some suppliers at CPSES (GE Co in particular) that it was necessary to bend terminals for internal wiring up to 120*. It was pointed out that for these cases, the application was for short jumpers (normally under 18 inches), and as such, the full me,chanical strength of the connector was not required. Floyd Renshaw responded that the current AMP position was that the subject teiminals could be bent one time to a 90* bend or two times to a 45* bend. Howmer, this does not pr.eclude bending the terminals up to 120*. In this case, an Engineering evaluation for the specific type of application could be done by the product user. Items that should be taken into account are as follows: a) length of wire to be supported by the terminal b) the susceptibility to vibrations c) once installed if it is contemplated rebending these tenninals, they should be discarded and replaced by a new terminal. Floyd Renshaw also advised that while a terminal bent more that 90* to 120' would not retain its full mechanical strength it would mainatin its electrical characteristics., Ny.a,. cc: ARMS % rS* 1..M.

SUMMARY
OF DISCUSSION. DECISIONS AND CDMMnMINTL W. I. Vogelsang discussed the AMP memo dated September 2,1981*in which Mr. B. Eister had indicated a 60* bend without reannealing was acceptable. It was discussed that with some suppliers at CPSES (GE Co in particular) that it was necessary to bend tenninals for internal wiring up to 120. It was pointed out that for these cases, the application was for short jumpers (normally under 18 inches), and as such, the full mechanical strength of the connector was not required. Floyd Renshaw responded that the current AMP position was that the subject teiminals could be bent one time to a 90* bend or two times to a 45 bend. However, this does not pr.eclude bending the terminals up to 120*. In this case, an Engineering evaluation for the specific type of application could be done by the product user. Items that should be taken into account are as follows: a) length of wire to be supported by the terminal b) the susceptibility to vibrations c) once installed if it is contemplated rebending these tenninals, they should be discarded and replaced by a new tenninal. Floyd Renshaw also advised that while a terminal bent more that 90 to 120 would not retain its full mechanical strength it would mainatin its electrical characteristics. y.dw - I cc: ARMS s M L.M.

INTRODUCTION This report cbntains results of tests conducted on PIDG PVF2 radiation resistant terminals. Testing was conducted to evaluate the products 0 and 900 and a performance when subjected to bending of terminal tongues of 60 twist of the tongue approximately 45 These variations were subjected to Millivolt drop followed by vibration and a final millivolt drop measurement per MIL-T-79286. Testing was conducted in AMP Laborat"-irr tarin: "r renth of March, 1985 h TEST SPECIMEN DESCRIPTION I.QN d' The following Terminals and quantities were tested. )P]\\/ Quantities ner u vuu Terminal Part No. Wire size Groue 1 Group 2 Groue 3 53425-1 10 AWG 4 @ 600 Bends 4 @ 900 Bends 4 @ 450 Twists Wire used for testi,ng was per MIL-W-5086 with tin plated copper strands. TEST SCHEDULE Terminals were subjected to the following test in the sequence specified. Test Group and Sequence Test Groun 1 Groue 2 Groun 1 Voltaae Droe 1-3 1-3 1-; Vibration 2 2 2 TEST METHODS Voltare Dron. Each terminal was measured for voltage crop by energizing with 55 amperes with DC current s.nd probing at the intersection of the tongue and wire barrel and a point on the wire 6" back from the terminal probe point. Vibration. Terminals were rigidly mounted to and not more *.han 1 inch above the vibrating platform by their normal mounting means. The test terminals were so mounted *. hat the Junction of the other end of the test sample was secured to a stable support 12 inches external to the vibrating table with all slack or tension removed from the wire. The specimens were vibrated in accordance with method 201 of MIL-STD-202 for 18 hours on each of two axes mutually perpendicular to each other and to the axis of the wire. TEST DATA

- Sample broke after 9 0 hours in the first plane of Vibration.
The sample was bent 600 and broke in the transition area between the tongue and wire barrel. All other samples displayed no signs of physical damage. APPEN, DIX A The sample which broke off after 9 0 hours in the first plane of vibration apparently was mounted improperly as all of the remaining samples of group 1 and the other two groups went the full 18 hours of both planes without displaying any signs of physical damage. Based on the information acquired from this test, we can say that any static application, with little or no vibration present, should see no detrimental results through bending of the togue on a one time basis to 600 or 900 The same can be said of the twisted tongue to 450 Even if the terminals were to face moderate vibration such as that set up by heavy equipment running, we feel that the testing proves that the terminations will withstand such a condition without any detrimental affects.

r. 1 INTRODUCTION i This report cbntains results of tests conducted on PIDG PVF2 radiation resistant terminals. Testing was conducted to evaluate the products performance when subjected to bending of terminal tongues of 600 and 900 and a twist of the tongue approximately 45 These variations were subjected to Millivolt drop followed by vibration and a final millivolt drop measurement per MIL-T-79286. Testing was conducted in AMP Laboratories during the month of March, 1985 TEST SPECIMEN DESCRIPTION A The following Terminals and quantities were tested.

Each terminal was measured for voltage drop by energizing with 55 amperes with DC current and probing at the intersection of the tongue and wire barrel and a point on the wire 6" back from the terminal probe point. Vibration. Terminals were rigidly mounted to and not more than 1 inch above the vibrating platform by their normal mounting means. The test terminals were so mounted that the junction of the other end of the test sample was secured to a stable support 12 inches external to the vibratin6 table with all slack or tension removed from the wire. The specimens were vibrated in accordance with method 201 of MIL-STD-202 for 18 hours on each of two axes mutually perpendicular to each other and to the axis of the wire. 1-

- Sample broke after 9 0 hours in the first plane of Vibration.
The sample was bent 600 and broke in the transition area between the tongue and wire barrel. All other samples displayed no signs of physical da 7ma '- APPENDIX A The sample which broke off after 9 0 hours in the first plane of vibration apparently was mounted improperly as all of the remaining samples of group 1 and the other two groups went the full 18 hours of both planes without displaying any signs of physical damage. Based on the information acquired from this test, we can say that any static application, with little or no vibration present, should see no detrimental results through bending of the togue on a one time basis to 600 or 900 The same can be said of the twisted tongue to 450 Even if the terminals were to face moderate vibration such as that set up by heavy equipment running, we feel that the testing proves that the terminations will withstand such a condition without any detrimental affects.

W. I. Vogelsang discussed the AMP memo dated September 2,1981*in which Mr. B. Eister. had indicated a 60* bend without reannealing was acceptable. It was discussed that with some suppliers at CPSES (GE Co in particular) that it was necessary to bend terminals for internal wiring up to 120. It was 'd., pointed out th'at for these cases, the application was for short jumpers 'd (normally under 18 inches), and as such, the full mechanical strength of the connector was not required. Floyd Renshaw responded that the current AMP position was that the subject teiminals could be bent one time to a 90* bend or two times to a 45* bend. However, this does not preclude. bending the terminals up to 120*. In this case, an Engineering evaluation for the specific type of application could be done by the product user. Items that should be taken into account are as follows: a) length of wire to be supported by the terminal b) the susceptibility to vibrations c) once installed if it is contemplated rebending these tenninals, they should be discarded and replaced by a new terminal. Floyd Renshaw also advised that while a terminal bent more that 90* to 120* would not retain its full' mechanical strength it would mainatin its electrical characteristics., V:dw' cc: ARMS % W L.M.
