The specimens shall be mated, locked and
27、unmated so that plug and receptacle are completely separated, which constitutes one cycle. Mating and unmating may be carried out manually or unless otherwise specified with a mechanical device simulating manual operations provided the latter does not induce any excessive stresses. A counter shall r
28、ecord the number of mating and unmating operations. 4.2 Final measurements (if applicable) The specimens shall be subjected to the following test sequence: EN2591-101; EN2591-201 or EN2591-202; EN2591-205; EN2591-206; EN2591-207; EN2591-408; EN2591-312 or EN2591-313 or EN2591-314. 1) Published as AE
