QUALIFICATION: Connectors shall meet the qualification requirements of MIL-DTL-38999 with the
exceptions and additions specified below. Group C periodic requalification testing, including the selection
of Group C test samples, shall be in accordance with testing specified in this specification sheet and
MIL-DTL-38999 Group C, 24 month testing.
Durability:
Wired connectors shall meet the durability requirements of MIL-DTL-38999, with the following
exception: Total number of cycles of normal mating and unmating shall be 250 (200 cycles of normal
mating and unmating followed by 50 cycles of normal mating with pull-separation unmating).
Pull-separation at temperature:
In addition to mating and unmating by normal coupling ring rotation, the connector shall be capable of
lanyard-pull separation at any angle within 15° of the normal axis after exposure for 1 hour minimum at
the following temperatures as shown in table II: Room ambient temperature, -65°C (+ 0°C / -5 °C),
and at the maximum temperature of the specified class. Each connector shall have one straight (0°)
pull and one pull at 15° from straight, with a pull rate not exceeding 13 cm/second. Each pull test will
be conducted within three (3) minutes after removal from the temperature chamber without forced
heating or cooling. Maximum separation forces shall be as specified in table III.
