NOTE
a) Specimens shall be selected at random from current production. Test groups 1 and 2
each require 5 connector pairs terminated to 1.57 mm minimum thick LLCR PCB with
copper/OSP plated thru holes. Test group 3 requires 2 loose piece connector pairs.
Test Group 4 requires 5 connector pairs terminated to LLCR/Continuity PCB. Mated
connectors shall be held together with standoffs and fasteners. Test group 5 requires 5
connector pairs terminated to LLCR PCB. Test group 6 requires 4 connector pairs
terminated to special serial current test PCB. Test group 7 requires 5 connector pairs
terminated to LLCR PCB. Test group 8 requires 10 connector pairs terminated to
LLCR PCB. Numbers indicate sequence in which tests are performed.
b) First half of the total number of specified cycles.
c) Second half of the total number of specified cycles.
d) Ten days unmated.
e) Four days mated.
f) Five days unmated.
g) Five days mated.
