ECIA EIA-364-29B PDF

This standard establishes a test method to impose axial forces on the
connector contacts to determine the ability of the connector to
withstand forces that tend to displace contacts from their proper
location within the connector insert and resist contact pullout.  These
forces may be the result of:

     Loads on wire connected to the contacts.

     Forces required to restrict contact push-through during assembly of
     removable type contacts into connector inserts.

     Forces produced by mating contacts during connector mating.

     Dynamic forces produced by vibration and shock during normal use of
     the connectors.

     Forces relating to bundling strains on the wire.

The object of this test procedure is to detail a standard method to
assess the ability of the contact retaining system to withstand the
axial mechanical stresses likely to be encountered during normal usage.
