FIGURE 5. Angular test set-up.
4.5.8 Endurance. Failure to meet the requirements of 3.10.8 after either of the following two tests shall be
cause for rejection.
4.5.8.1 Wet. The wet endurance test shall consist of connecting and disconnecting the male and female halves
of the semi-dry-break, quick-disconnect coupling assembly in the normal manner 2000 times. The assembly shall
be pressurized to 60 PSI with test fluid (see 3.3.2) each time after the connection is made. The operating force test
(see 4.5.2) shall be conducted after each 200 connect-disconnect cycles. At the completion of this test, the leakage
test (see 4.5.3) shall be conducted.
4.5.8.2 Dry. The dry endurance test shall be conducted in a manner similar to the wet endurance test, except
that the duration of the test shall be 500 cycles, the male and female halves of the semi-dry-break, quick-disconnect
coupling assembly shall remain dry throughout the test, and no pressure shall be applied to the connected
components. The operating force test (see 4.5.2) shall be conducted at the completion of the dry endurance test
followed by the leakage test (see 4.5.3).
4.5.9 Electrical resistance. This test is applicable to all semi-dry-break, quick-disconnect coupling assemblies.
The electrical resistance shall be measured from an aluminum plate bolted to the flange of the male half of the semi-
dry-break, quick-disconnect coupling assembly through the male and female halves of the coupling to an adapter
threaded onto the inlet of the female half. The test setup shall be similar to Figure 6. The electrical resistance shall
meet the requirements of 3.10.9. Failure to meet these requirements shall be cause for rejection.
