The quick release mechanism shall not fracture nor disengage when a tensile force of 2.0 kN ± 50 N is progressively applied to the retention system in the direction in which the mechanism is designed to bear load. Following the application and removal of the force the quick release mechanism shall still be capable of operation.
Subject the quick release mechanism to the following procedures in the order given:-
Using apparatus appropriate to the particular design of mechanism carry out the following procedure. Close and lock the mechanism . Apply a loading force of 20 N in the direction in which the mechanism is designed to bear load, then unlock and disengage the mechanism under load. Complete this cycle in not less than 2s . Repeat for a total of 5000 CYCLE.
