Three sample plugs not subjected to any previous
tests shall be tested as follows:
tests shall be tested as follows:
Pins of assembled plugs shall be tested by
clamping the plug in a rigid holding block and
applying a bending force, as shown in Figure 2.8,
to the pin under test.

The pins shall be straight at the beginning of the
test. If there is any doubt about the straightness of
the pin, it shall be checked by the appropriate plug
gauge shown in Appendices A, B or F.

The direction of the force shall be along a line
parallel to the face of the plug.

starting point. Any earth pin shall be forced but in
one direction only and then back to the starting
