The radiation test program consisted of irradiating the non-operative specimens with Cobalt 60.

The seismic test program consisted of resonant search testing anc biaxial sine beat testing in 'each of two test: orientations. The specimens were instrumented with accelerometcrs, electrically powered, pressurized, and monitored for functional operation during thu seismic test program.

It was demonstrat:cd that t!Iu st)ccimens possessed sufficient int='-rity to wit:hstand, without compromise of st:l.uct:urus or functions, the prescribed simulated seismic environment.

e 1.0 TEST ITEl~)S (continued)

Items numbers 82075 to 82089 are pressure switches with single-pole/double-thro<< snap-action switches; one circuit closes as the .other. circuit opens. The model numbers with the suffix -153 designate units with a single SPDT switch; the model number with the suffix -804 designates a unit with dual SPDT switches, two close, two open.

Those model numbers with the prefix DAt!- designate units with double adjustment set points, one high. pressure set point and one low pressure set point. The dif'ference between the high and low set points is the operating differential between "on-off" switch operation. Those model numbers with the prefix DSH- designate units with single adjustment set points. The single set point sets the pressure where switch operation

, occurs; the operating differential is fixed.

Item Ho. 82090 is a differential pr essure switch which received a high and a low pressure input. Switch action is 0

determined by the difference in pressure between the two inputs:

This unit was not electrically 'monitored for switch action during the testing.

2.0 TEST RE UIREMENTS 2.1 RESONANCE SURYEY TEST RE UIREHENTS

.The purpose of the resonance survey specified in section 3.3 was to monitor the mechanical response of the test items to determine any resonant frequencies in the seismic bandwidth and to determine each test item's ability to withstand the specified vibration without evidence of mechanical damage or deterioration. The pressure switches were not pressurized

. during the resonance survey.

2.2 MULTIPLE.FRE UENCY TEST RE UIREMENTS The purpose of the multiple frequency test specified

.in section 3.4 was to determine the test items'bility to

.withstand such vibration without evidence of mechanical damage, deterioration, false closure of open contacts for longer than 3 milliseconds, or false opening of closed contacts for. longer than 10 milliseconds, or any other interference with proper operation as determined by opera-tional tests performed before and after the multiple frequency vibration.

CNVIRONMENTAL TESTlhKL paga AGTON

2.0 TEST RE UIREMENTS (continued)

The multiple frequency test was conducted in such a manner that the Test Response Spectra (TRS) at which the units were qualified would correspond to the SSE level of the Required Response Spectrum (RRS) or, if a failure occur red at that level, to the maximum level at which the unit would fulfill the above acceptance criteria.

3.0 TEST PROCEDURES 3.1 TEST MOUNTING Each Mercoid pressure switch was mounted on the vertical surface of.a steel plate vibration test fixture in the manner shown in Figures 1 and 2. After eacli Hercoid pressure switch was plumbed and mounted, the test fixture/test item assembly was securely attached to the 45'iaxial table of the AETC seismic test facility. The use of the 45'iaxial. table results in equal horiiontal and vertical input components.

3.2 TFST MONITORING During the multiple frequency vibration testing, test items 82075-82089 were electrically monitored to indicate any spurious opens and closures of the single-pole/double-throw switches. Across each of the open and closed contacts of the SPDT switches,' chatter monitoring circuit was connected. The chatter detector was set to monitor the open contacts for false closures longer than 3 milliseconds and to monitor the closed contacts for false openings longer than 10 milliseconds.

The output from the chatter monitor's gate circuitry was connected to an oscillographic recorder to record when Report No.

During the vibration testing, the tlercoid pressure switches were visually monitored for signs of mechanical damage or deterioration. Item number 82090, the Nercoid differential pressure switch, was monitored visually only, without any additional electrical monitoring.

3.3 RESONANCE SURVEY The resonance survey consisted of a biaxial sinu-soidal input with peak horizontal and vertical accelera-tion components of 0.2 g at frequencies from 1 to 35 Hz.

The resonance survey was performed at a sweep rate of 1 octave/minute. For each group of test items, the input was applied in two (2) horizontally perpendicular biaxial directions of excitation as follows:

Front-to-back and vertical Right-.to-left and vertical 3.4 MULTIPLE FRE UENCY TESI The multiple frequency test consisted of a biaxial pseudo-random excitation.

The outputs from the 14 channels were played back and combined in .a 14-channel mixer which resulted in the pseudo-random multiple frequency test input. .The indivi-dual mixer channels have attenuation controls so that the.

level of each tape channel output passing through the I

mixer could be controlled. In this manner, the Test Response Spectrum was shaped by controlling the level of the individual frequencies. /

The test input was adjusted such that the Test Response" Spectrum from the control accelerometer, computed at /=20, 2 1/2X damping, enveloped the appropriate Required Response Spectrum 'shown in Figure 10. The test inputs were applied seven (7) times in each of four (4) horizontally perpendi-cular biaxial directions of excitation. The test duration for each input was thirty (30) seconds.

The levels of the first five (5) inputs in each biaxial direction were such that the TRS from the control accelero-meter would envelope the OBE RRS shown in Figure 10. The levels of the sixth and seventh inputs in each biaxial o 16013-2 E NVIRONMENTAl.

3.0 TEST PROCEDURES (continued)

Item number 82090, the Hercoid differential pressure switch, was- supplied with a 13 psig pressure input to its high side and a 12.75 psig pressure input to its low side.

These pressures were maintained constant during the multi-pie frequency te't runs.

For those test items which failed to fulfill the qualification acceptance criteria during the SSE levels of multiple'frequency testing (test runs I5'6 8 87),

additional testing was done at lower vibration input levels until a maximum level was'etermined at which the unit would qualify.. The additional multiple frequency testing was conducted using RRS curves of 3/4 SSE, 1/2 SSE, and 1/4 SSE as shown in Figure ll. The additional test runs were each 30 seconds in duration.

3. 5 OPERATIONAL TEST Operational tests were performed on test items 82075-82089 before and after vibration testing as specified in section 3.4, and before and after environmental testing as specified in section 3.6. The operational status of each Mercoid pressure switch was verified by the following operati on test.
