10、 for ResaleNo reproduction or networking permitted without license from IHS-,-,-MS25917H 4 Environmental requirements: Temperature range: -65C to +120C. Shock (specified pulse): Applicable, MIL-STD-202, method 213, test condition A, 25 gs, 6-9 milliseconds. Contact chatted shall no exceed 10 microse
11、conds maximum opening for closed contacts and 1 microsecond maximum closure for open contacts. Vibration (sinusoidal): Applicable, MIL-STD-202, method 204, test condition A, 10 gs or .036 DA whichever is less, from 5 to 500 Hz. Contact chatter shall not exceed 10 microseconds maximum opening for clo
12、sed contacts and 1 microsecond maximum closure for open contacts. Hermetically-sealed (potted) relay: Relays shall be tested as follows: a. Prior to installing a gasket on the relay header (if a gasket is used), the relay shall be totally immersed in a container of “tap” water. (The “tap” water as u
13、sed here means ordinary drinking water that has not been altered in any way, such as by the addition of any other substance or distilling). The part of the relay closest to the surface of the water shall be a minimum of 1 inch (25.4 mm) below this surface. b. The container and water-covered relay sh
14、all then be placed in a vacuum chamber. The chamber shall be sealed. The chamber pressure shall be reduced from room ambient to 0.82 inch (80,000 feet) +0.0 inch- 0.2 inch of mercury within 5 minutes, and shall be maintained at this level for 30 minutes minimum. The chamber pressure shall be increas
15、ed to room ambient within 1 minute, and shall be maintained at room ambient pressure for 30 minutes, minimum. The foregoing shall constitute one cycle. The relay shall remain fully immersed in the water during the cycle. c. Within a maximum of one-half hour after the cycle, each relay shall be remov
16、ed from the water and dried by shaking, wiping, or blowing with contaminant-free air or gas, but not by any form of heating or baking. d. Within a maximum of one-half hour after drying, each relay shall be subjected to the DWV and IR tests. Life test requirements 50,000 cycles minimum. Qualification
17、 by similarity: If the relay case, frame, or enclosure contains integral sealed electromagnetic relays (mounting means excepted) currently listed on the qualified products list of MIL-PRF-83536/5, reduced testing shall consist of subjecting four sample units to the shock and vibration requirements o
18、f this specification sheet. Post tests shall include insulation resistance, dielectric withstanding voltage and electrical characteristics, and seal. One unsealed unspotted unit shall be submitted to the qualifying activity. VERIFICATION: Group A: a. Group A1: Run-in. This subgroup may be waived by
19、the qualifying activity if fully tested sealed MIL-PRF-83536/5 relays are used internally. b. Group A2: 100 percent. c. Dielectric withstanding voltage: (1) Tests to be conducted at sea level rating only. (2) Duration of application: 5-10 seconds at a 10 percent increase in the dielectric strength v
20、oltage. Group A acceptance reports shall be submitted to the qualifying activity on a yearly basis in order to retain qualification for this detail specification sheet.
