Preparation of specimens 3.1 Elements of connection shall be fitted with wired contacts. The bundle of wires shall be maintained by the
9、 accessory specified by the technical specification. 3.2 Unless indicated in the technical specification, the following details shall be specified : - type of elements of connection, - type of cable and cross-section, - test is to be carried out manually, - test is to be carried out inechanically, w
10、ith rate of operation, - number of operations, - rate, - method and requirement for final measurements. 4 Method 4.1 Procedure The specimens shall be submitted without electrical load, to the number of mating- unmating operations and at the rate specified by the technical specification. The specimen
11、 shall be mated, locked and 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 by the technical specification with a mechanical device simulating manual operations provided the latte
12、r does not induce any excessive stresses. A counter shall record the number of mating-unmating operations. The specimen shall be operated at the rate specified and for the number of cycles specified by the technical specification. 4.2 Final measurements (if applicable) - EN 2591-A1 - Visual examinat
