inch per minute. Apply force
perpendicular to axis of wire on
samples without cover.
TE Spec 109-21-1, Condition A.
10-55-10 Hz traversed in 1 minute
at 0.06 inch total excursion. 2 hours
in each of 3 mutually perpendicular
planes.
TE Spec 109-27.
Manually mate and unmate
connector assemblies for 25 cycles.
Mount connector in fixture.
TE Spec 109-30.
Pull on contact using special cut-
away housing.
