Apparatus for Checking the Withdrawal Force meets the standard of EN/IEC 60320-1, Clause 16.2, Figure 3.
Apparatus for Checking the Withdrawal Force Test Procedure:
The appliance inlet/plug connector is fixed to the mounting plate A of an apparatus as shown in Figure 3,
so that the axes of the appliance inlet/plug connector pins are vertical and the free ends of the pins are downwards.
The total mass consists of the principal mass, the supplementary mass, the clamp and the carrier.
The connector/appliance outlet is inserted to the full depth into, and withdrawn from, the appropriate appliance inlet/plug connector 10 times.
It is then again inserted, a carrier E for a principal mass F and a supplementary mass G being attached to it by means of a suitable clamp D.
The supplementary mass is such that it exerts a force equal to one tenth of the maximum
withdrawal force specified in Table 5 and it shall be made in one piece.
The principal mass is hung on the connector/appliance outlet without jolting
and the supplementary mass is allowed to fall from a height of 5 cm on to the principal mass.
The connector/appliance outlet shall not remain in the appliance inlet/plug connector.
