25、gle 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 of30mm. 5 Method 5.1 Initial measurements (if applicable) Specimens shall

26、 be subjected to the following test sequence: EN2591-408, mating force; EN2591-201 or EN2591-202; EN2591-207. 5.2 Procedure The specimens shall be tested to EN2591-313 (without initial nor final measurements) and then immediately to EN2591-310 at a temperature of(55 2)C for1h. Then, within2min, the

27、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. The unmating force shall be applied after the lanyard has first been made taut wit
