3.14.8.2 Withdrawal force test
: r3 s$ V, y, v9 t. UThis test is applicable only to socket-outlets rated at up to and including 10 A, and intended for use with plugs of the type shown in Figure 2.1(a1). The test shall be applied to all the socket-outlets subjected to the test of Clause 3.14.8.1.
6 { P8 J2 L$ |1 XPlugs rated at 10 A and complying with Figure 2.1(a1) of this Standard and which have not been subjected to any previous tests shall be used. A separate plug shall be used for testing each socket-outlet.. @$ f% D& g/ K
Manually insert the plug fully into and withdraw it from the socket-outlet 10 times.

Manually align the plug in the socket-outlet to minimize the effects of misalignment between mating components and any other friction-increasing factors, to attain the best practical position for minimum resistance to withdrawal.( `( t% a. |6 q2 f2 P
NOTE: When testing in other than the horizontal plane, the mass of the plug and socket-outlet is to be considered in all measurements.
