MIL-R-5757J
Four pole relays shall be tested as follows:
Samples 1 through 4 (pole 1): 0.1 ampere resistive at 28 ±1 V dc.
(pole 2): 0.3 ampere inductive load (220 mH at 28 ±1 V dc. (pole 3): 0.5 ampere resistive at 28 ±1 V dc.
(pole 4): rated resistive load at 28 ±1 V dc.
Six pole relays shall be tested as follows:
Samples 1 through 4 (pole 1): 0.1 ampere resistive at 28 ±1 V dc.
(pole 2): 0.3 ampere inductive load (220 mH) at 28 ±1 V dc. (pole 3): 0.5 ampere resistive at 28 ±1 V dc.
(pole 4): rated resistive load at 28 ±1 V dc. (pole 5): 0.1 ampere resistive at 28 ±1 V dc. (pole 6): rated resistive load at 28 ±1 V dc.
4.6.23 Mechanical life (see 3.25). Relays shall be cycled one million cycles at room ambient temperature. The cycling rate shall be as specified in 4.6.20.4. Each contact load shall be 10 µA to 50 µA at 10 mV to 50 mV (dc or peak ac). The coil shall be energized at rated voltage (or current) during 50 percent ±10 percent of each cycle.
4.6.24 Resistance to solvents (see 3.26). Relays shall be tested in accordance with method 215 of MIL-STD-202. The following details and exceptions shall apply:
a. Portion to be brushed: All marking.
b. Specimens to be tested: One sample shall be tested with each solvent solution. For qualification inspection, samples in excess of the available number of solvents shall be exempt from test. For group C testing, two additional samples shall be selected. The additional samples may be electrical rejects from group A2.
c. Examination: Specimens shall be examined for legibility of marking.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Point's packaging activities within the Military Service or Defense Agency, or within the military service's system commands. Packaging data retrieval is available from the managing Military Department's or Defense Agency's automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)
6.1 Intended use. Relays conforming to this specification are intended for use in electronic and communication equipment. Their principal areas of application are for aircraft, missiles, spacecraft and ground-support electronic and communication equipment. This does not preclude the use of these relays in other military applications. The relays covered by this specification will be able to operate satisfactorily in systems under the following demanding conditions: vibration up to 15 g's shock of 100 g's, and temperature ranges of -65°C to +125°C
CAUTION: The use of any coil voltage (or current) less than the rated coil voltage (or current) will compromise the operation of the relay.
