A. SHOCK AND VIBRATION TEST=
', Y The L'imitorque Operator size SMB-0 with a 15 foot pound, 3 phase, 60 cycle, 440 volt motor, nameplate order 5338164 was shipped to Lockheed Electronics Company environmental labratory and tested on March 10, 1969.
Test Procedure The. test specimen was secured to a vibration machine and subjected to- five cycles of vibration in both the vertical axis and the horizontal axis. Each cycle consisted of two minutes of vibration at a frequency of thirty-five (35) cps and an acceleration level of three (3) "G's", followed by one minute of no vibration.
Vibration scans were also conducted in both axis of vibration between five to thirty-five cps to determine the presence of any
'I resonances.
Visual inspections for evidence of any external physical damage were conducted throughout the vibration testing. The vibration test was completed with no visual evidence of any external physi-cal damage. No resonances were detected du'ring the vibration scans.
The above is included in Lockheed Electronics Company Test Report
<'r 02268-4618.

Page April 29, 1969 The previous shock and vibration test of a Limitorque Operator was extended to '1 6 and 25 cps. The above test extended the level to 3 G's at 35 cps.
B. 'EST OF GEARED LIMIT SNITCH NITH MATERIAL CHANGE:
On, the previous test of a Limitorque Operator as submitted January 2, 1969, a failure occurred due to the action of the chemical spray on the material of the gear frame of the geared limit, switch. Thi,s caused the premature, fa ilure of the geared limit switch. The gear frame material has been changed as prev-iously recommended and an additional test of this revised geared limit switch ha's been conducted at The Franklin Institute Research Labratories in Philadelphia, Pennsylvania on April 9 through April 16, 1969. The geared limit switch was placed in the same environmental chamber as the previous test and was used in conjunction with starting and stopping an electric motor also in the test chamber. The environment consisted of a seven day test wherein the geared limit switch was exposed to high steam pres'sure, temperature and chemical environment similar to the previous test.
The new geared limit switch successfully completed the test with no sign of wear or deterioration due to the steam pressure,
0' Page 29, 1969 temperature or chemical environment. The test was completely satisfactory in every respect.
CONCLUSION:
The material change of the geared limit switch has been noted and will be included on all Limitorque Operators subjected to this environmental condition when specified.
