MIL-DTL-83729C
3.9 Insulation resistance (IR) (see 4.6.5). Unless otherwise specified (see 3.1), the IR between mutually insulated
terminals and between terminals and case which do not normally form a conductive circuit, shall be at least 1,000 MΩ
or greater.
3.10 Thermal shock and high and low temperature operation (when specified) (see 3.1) (see 4.6.6). The
waveform characteristics, contact resistance (dynamic), starting voltage, IR, and DWV shall be as specified in 3.7.7,
3.11 Salt spray (corrosion) (see 4.6.7). There shall be no corrosion of base material, nor shall oxidation of the
plating be such that it would interfere with normal operation of the chopper. The contact resistance, dc coil
resistance, and waveform characteristics (with nominal drive only) (see 6.5) shall be as specified in 3.7.1, 3.7.2, and
3.7.7, respectively.
3.12 Sand and dust (when specified) (see 3.1, 4.6.8, and 6.2.2). There shall be no evidence of mechanical or
electrical damage. At the end of the test, the dielectric withstanding voltage, and waveform characteristics (with
3.13 Vibration (see 4.6.9). There shall be no evidence of mechanical or electrical malfunction during or after the
test. Following the test, the IR, DWV, contact resistance (dynamic), seal, coil impedance, noise level, starting
voltage, and waveform characteristics (with nominal drive only) shall meet the requirements of 3.9, 3.8, 3.7.1, 3.6,
3.14 Acceleration (when specified) (see 3.1, 4.6.10, and 6.2.2). The waveform characteristics (with nominal drive
only) shall be as specified in 3.7.7.
3.15 Terminal strength (see 4.6.11). There shall be no evidence of loosening or breaking of the terminals,
damage to the insulating base of the choppers, or detrimental effect on the seal. Bending of terminals shall not be
construed as damage provided that sealing is not effected in the process and that plug-in terminals can be reformed
in a manner to permit proper mating with the applicable socket. There shall be no damage which would adversely
affect the normal operation of the choppers.
3.16 Moisture resistance (see 4.6.12). There shall be no evidence of excessive peeling, flaking, chipping,
cracking, or grazing of the protective coating. Marking shall be legible at the completion of the test. Following the
moisture resistance test and after the 24-hour drying period, contact resistance, IR, DWV, dc coil resistance, coil
impedance, and waveform characteristics (with nominal drive only) shall be as specified in 3.7.1, 3.9, 3.8, 3.7.2,
3.17 Barometric pressure (reduced) (when specified) (see 3.1, 6.2.2, and 4.6.13). The waveform characteristics
(with nominal drive only) shall be as specified in 3.7.7.
3.18 Shock (see 4.6.14). There shall be no evidence of mechanical or electrical damage, nor shall the test impair
the normal operation or cause any malfunction after the test. During the test, a transient increase in dissymmetry
may occur. Following this test, waveform characteristics (with nominal drive only), starting voltage and DWV shall be
3.19 Life. Unless otherwise specified (see 3.1 and 6.2.2), choppers shall be tested in accordance with 4.6.15.
Before, during, and after life test, the IR, DWV, static and dynamic contact resistance, waveform characteristics and
3.20 Marking. Unless otherwise specified (see 3.1 and 6.2), choppers shall be marked in accordance with
method I of MIL-STD-1285 and shall include as a minimum the following information:
(a)
(b)
Date code.
(c)
Source code.
(d)
Lot symbol.
(e)
Coil rating (voltage, and frequency).
3.21 Interchangeability. All parts having the same PIN shall be directly and completely interchangeable with each
other with respect to installation and performance to the extent specified in the associated specification sheet (see
3.1).
