MIL-R-83407C
3.20 Moisture resistance (when specified) (see 3.1). When relays are tested as specified in 4.5.17, there shall be no evidence of breaking, cracking, chipping, or flaking of the finish or loosening of the terminals. Immediately after step 6 of the final cycle, the insulation resistance shall be 100 M or more. After the 24 hour drying period, the dielectric withstanding voltage, insulation resistance, contact resistance, and pickup and dropout voltages shall be as specified in 3.6, 3.7, 3.11, and 3.9, respectively.
3.21 Magnetic interference. When relays are tested as specified in 4.5.18, the pickup and dropout values shall be within the limits specified (see 3.1).
3.22 Resistance to soldering heat. When relays are tested as specified in 4.5.19, the insulation resistance, contact resistance, pickup and dropout voltage, and dc coil resistance shall be as specified in 3.7, 3.11, 3.9, and 3.8, respectively.
3.23 Salt spray (corrosion). When relays are tested as specified in 4.5.20, there shall be no evidence of breaking, cracking, chipping, or flaking of the finish, or exposure of the base metal due to corrosion, which would adversely affect the performance of the relay.
3.24 Terminal strength. When relays are tested as specified in 4.5.21, terminals shall be as specified (see 3.1) and there shall be no evidence of loosening or breaking of the terminals or other damage that could adversely affect the normal operation of the relays. Bending of printed circuit terminals shall not be construed as damage, provided they can be satisfactorily reformed to their original configuration.
3.25 Life. When relays are tested as specified in 4.5.22, they shall remain electrically operative and no mechanical damage shall exist. During and following this test, the relays shall meet the following requirements:
DC coil resistance - - - - - - - - - - - - - - - - - As specified in 3.8. Contact resistance - - - - - - - - - - - - - - - - As specified in 3.11. Pickup and dropout voltage - - - - - - - - - - As specified in 3.9. Operate and release time - - - - - - - - - - - As specified in 3.12. Dielectric withstanding voltage- - - - - - - - As specified in 3.6. Insulation resistance - - - - - - - - - - - - - - As specified in 3.7.
3.26 Marking. Relays shall be marked in accordance with MIL-STD-1285 with the following information, as a minimum:
a. Military Part or Identifying Number (PIN). b. Circuit diagram (see 3.1).
c. CAGE (FSCM) and date codes. d. Position direction arrow t.
e. Rated coil voltage.
3.27 Soldering. Electrical connections shall be mechanically secure and electrically continuous before and after soldering.
3.28 Screening (when specified) (see 3.1).
3.28.1 Temperature cycling. Each relay shall be tested as specified in 4.5.23.1.
