A tensile load is smoothly applied to a mated connector set or connector and device combination in a direction that will separate the components. The load is normally applied between the connector plug and the adapter or between the connector plug and the dev ice being tested.
The test apparatus shall be capable of applying an axial load between a connector plug or coupling mechanism and an adapter or dev ice. An example of a test apparatus is shown in Figure 1 . Some or all of the following apparatus components will be required.
4.2 Force generator
The force generator may be any device or apparatus capable of smoothly applying the specified force at the specified rate.
4.3 Force gauge
A force gauge of specified accuracy shall be used to measure the axial force applied to the device under test (DUT).
4.4 Clamping device
A suitable clamping dev ice shall be used to couple the force generator to the connector plug or coupling mechanism. Care shall be taken in the design and use of the clamping device to ensure that it does not apply compressive forces which might influence the performance of the connector plug or coupling mechanism.
4.5 Specimen mount
Mount the specimen according to normal mounting procedures.
4.6 Torque wrench
A torque wrench may be required to assemble screw type connectors in accordance with the manufacturer’s instructions.
5 5.1 Procedure
Prepare specimens Mate the specimens according to the manufacturer’s instructions. For screw type couplings, use a torque wrench to ensure that the couplings are tightened to the proper value.
Unless otherwise specified, pre-condition each prepared specimen for 2 h at the standard test conditions specified in IEC 61 300-1 .
