26、 of specimens 3.1 Specimens shall be prepared according to the technical specification. 3.2 Unless specified in the technical specification, the following details shall be stated: method of mounting, type of cable and definition of specimen wiring; initial measurements (if applicable); mating and un
27、mating forces; contact resistance; value of the pull-out force; angle of application of the pull-out force; number of tests per direction; value of the test voltage; final measurements (if applicable). 4 Apparatus The test equipment shall provide a pulling speed of (5,5 0,5) m/s after a travel of 30
28、 mm. 5 Method 5.1 Initial measurements (if applicable) Specimens shall be subjected to the following test sequence: EN 2591-408, mating force; EN 2591-201 or EN 2591-202; EN 2591-207. 5.2 Procedure The specimens shall be tested to EN 2591-313 (without initial nor final measurements) and then immedia
29、tely to EN 2591-310 at a temperature of ( 55 2) C for 1 h. Then, within 2 min, the specimens shall be mounted on the test equipment and disengaged by applying a force in the four directions to the lanyard as shown in Figure 1. The angle of application of the pull-out force (!) shall be as specified.
30、 The unmating force shall be applied after the lanyard has first been made taut without stress. 5.3 Final measurements (if applicable) The specimens shall be subjected to the following test sequence: EN 2591-101; EN 2591-408, for the mating force; EN 2591-201 or EN 2591-202; EN 2591-207, method A. 1
