The essential features of the apparatus should ensure that the tensile force can be applied In a truly axial direction and that torque can be applied without changing the tensile force. To minimize the effects of friction of the apparatus, the tensile force should be measured directly between the 22 mm latching socket and the test cone.
F.l.2 Procedure
F.1.2.1 Secure the 22 mm latching socket to be tested in the self-centring holder of the apparatus (ELI). ensuring that the method of securing the 22 mm latching socket does not deform the section or sections that are intended to engage with the test cone.
F.1.2.2 Condition the 22 mm latching socket and the apparatus at a temperature of (35 ± 3) °C and a relative humidity of at least 80 % for 1 h.
II a number of 22 mm latching sockets are to be tested, some can be conditioned at the required temperature and relative humidity without being secured to the apparatus, provided that they are conditioned again for at least 5 mm after being secured to the apparatus.
F.12.3 Engage the 22 mm latching sockets with the test cone in accordance with the manufacturer’s instructions.
F.1.2.4 After 1 mm, attach the force-measuring device and apply an axial separation force at a rate not exceeding 20 N.s-i until a force of (50 ± 5) N is being applied. Maintain this force for 10 s without activating any disengagement mechanism, and observe whether the engaged 22 mm latching socket and test cone become disconnected.
F.1.2.5 Without reducing the tensile load and without activation of any disengagement mechanism. apply a torque of (25 t 5) N/cm or rotate the test cone through an angle of 20, whichever occurs first. Maintain this torque or position for I Os and observe whether the engaged 22 mm latching socket and test cone become disconnected.
