MIL-PRF-24236/15J
Terminal strength: Method 211 of MIL-STD-202. Test conditions A and E, with 25 inch-pounds for condition E.
Moisture resistance: Measurements shall be taken upon completion of tests and again after switches have dried.
Insulation resistance shall be not less than 2 mega ohms.
Flame response: Applicable. Flame tests shall be conducted using the burner and method of flame temperature
measurement specified in MIL-F-7872. The flame shall completely envelop the sensing element of the switch.
Starting ambient for flame response shall be a minimum of 200F below switch operating temperature, or room
ambient, whichever is greater. The switch shall be cooled to this ambient following each exposure. No other test
shall be performed on a sample unit after Flame response.
Vibration: Monitor for contact closure or opening, as applicable, during resonance search. There shall be no
loosening of terminal hardware. Calibration check after testing, shall be within ±25F of pretest temperature
setting.
Shock: Applicable. Testing to be conducted at room ambient and without electrical load and thermal conditions.
No measurements to be taken during testing. Calibration test at conclusion shall be within ±25F of pretest
temperature setting.
Endurance: 2,000 cycles. Final setting to within ±30F of pretest of temperature setting.
Sand and dust: Not applicable.
Test sampling: Fifteen sample units shall be subject to qualification testing. They shall be set, 5 each, to 215F,
600F, and 900F, prior to the start of testing. For quality conformance inspection every fifth sample unit
undergoing the inspection shall be set to 250F, tested, reset to 900F, and tested. The applicable terminal
hardware shall be installed on each sample unit prior to testing, and shall be kept on throughout the tests.
Part or Identifying Number (PIN): M24236/15- (dash number from table I).
