3General
A tensile load is smoothly applied to a mated connector set or connector and devicecombination in a direction that will separate the components. The load is normally appliedbetween the connector plug and the adapter or between the connector plug and the devicebeing tested.
4Apparatus
4.1General
The test apparatus shall be capable of applying an axial load between a connector plug orcoupling mechanism and an adapter or device.An example of a test apparatus is shown inFigure 1.Some or all of the following apparatus components will be required.
4.2Force generator
The force generator may be any device or apparatus capable of smoothly applying thespecified force at the specified rate.
4.3Force gauge
A force gauge of specified accuracy shall be used to measure the axial force applied to thedevice under test (DuT).
4.4Clamping device
A suitable clamping device shall be used to couple the force generator to the connectorplug or coupling mechanism. Care shall be taken in the design and use of the clampingdevice to ensure that it does not apply compressive forces which might influence theperformance of the connector plug or coupling mechanism.
4.5specimen 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 Procedure
5.1 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.
5.2 Pre-conditioning
Unless otherwise specified, pre-condition each prepared specimen for 2 h at the standard test conditions specified in IEC 61 300-1 .
5.3 Initial examinations and measurements
Complete initial examinations and measurements on the specimen shall be made as required by the relevant specification. Visual examination shall be done according to IEC 61 300-3-1 .
