Test Method For Apparatus For Checking The Withdrawal Force:

The switched EV socket-outlet or switched vehicle connector with interlock is fixed to the support of an apparatus as shown in Figure 13 so that the axis of separation is vertical, and the movement of the mating accessory is downwards. With the latching devices holding the Ev plug into the EV socket-outlet, or vehicle connector into the vehicle inlet, in the engaged position, an axial pull is applied to an appropriate EV plug inserted in the switched EV socket-outlet, or vehicle connector inserted into the vehicle inlet, with interlock. The test EV plug orvehicle inlet, in accordance with the relevant standard sheets, shall have finely ground contacts of hardened steel, having a surface roughness not exceeding 0.8 pm over their active lengthand spaced at the nominal distances, with a tolerance of ±0.05 mm.

The EV plug contacts are wiped free from grease before the test.

The test EV plug, or vehicle connector, is inserted into and withdrawn from the EV socket-outletor vehicle inlet, ten times. lt is then inserted again with a mass being attached to it by means of a suitable clamp. The total mass of the mating accessory, the clamp, the carrier, the principal and the supplementary weight shall exert a force according to Table 5 upon the connection point. The supplementary weight shall be such that it exerts a force equal to one-tenth of the withdrawal force. The retaining means, if any, shall be opened.
The principal weight is hung without jolting on the test mating accessory, and the supplementary weight is allowed to fall from a height of 5 cm onto the principal weight.
After this test, the total weight shall be maintained for 60 s.
