MIL-DTL-62548C(AT)
4.2.4.5 Nuclear hardening. To determine conformance to 3.3.5, verify that the ignition
lead meets nuclear environment requirements as specified in LS199000006173, shall be
determined by the acquisition activity on the basis of circuit analysis and laboratory testing or
through nuclear test of a complete vehicle.
4.2.5 Interface requirements verification.
4.2.5.1 Electromagnetic interference (EMI). To determine conformance to 3.4.1, the
ignition lead shall be tested in accordance with MIL-STD-461 or equivalent.
4.2.6 Support and ownership requirements verification.
4.2.6.1 Identification marking. To determine conformance to 3.5.1, verify the presence
of the required markings on the lead ignition. After performing all environmental tests in 4.2.7,
re-inspect the lead ignition markings for readability.
4.2.6.2 Interchangeability. To determine conformance to 3.5.2, the interchangeability
between different parts, subassemblies, and assemblies having the same military part number
shall be verified using one or more of the methods described in 4.2.
4.2.6.3 Safety. To determine conformance to 3.5.3, the lead ignition shall be inspected
to assure that the mechanical components are free of hazardous burrs, nicks, sharp edges, foreign
materials, or other imperfections posing physical danger to the operators, and that the lead
ignition electrical components are free of exposed, frayed, unsecured, or otherwise improperly
protected circuits posing electrical danger to the operators.
4.2.7 Operating environment requirements verification.
4.2.7.1 High temperature test. To determine conformance to the high temperature
portion of 3.6.1 and following test 4.2.4.4, the ignition lead shall be subjected to a high
temperature of 212F (100C) for a period of 100 hours. Upon completion, the lead shall be
subjected to and pass the tests of 4.2.4.2 and 4.2.4.3.
4.2.7.2 Room temperature test. To determine conformance to the room temperature
portion of 3.6.1 and following test 4.2.7.1, the ignition lead shall be subjected to room a
temperature of 77F (25C) for a period of 8 hours. Upon completion, the lead shall be subjected
to and pass the tests of 4.2.4.2 and 4.2.4.3.
4.2.7.3 Low temperature test. To determine conformance to 3.6.1 and following test
4.2.7.2, the ignition lead shall be subjected to low temperature of 65F (54C) for a period of
30 hours. Upon completion, the lead shall be subjected to and pass the tests of 4.2.4.2 and
4.2.4.3.
4.2.7.4 Operational altitude range test. To determine conformance to 3.6.2, ignition lead
shall be subjected to a maximum atmospheric pressure of 31.19 inches of mercury (1300 feet
