注2︰万一遮蔽片失效，可用手动操作的办法对带遮蔽片的插座重复进行试验。
Socket-outlets are tested using a test plug with brass pins provided, if applicable, with insulating sleeves,
and having the maximum specified dimensions, with a tolerance of+0/-0.06 mm, and spaced at the nominal
distance, with a tolerance of+0.05/0 mm. As far as the extremities of the sleeves are concerned, it is sufficient that their dimensions are within the tolerances given in the relevant standard sheet.
插座使用具有黄铜插销的试验插头做试验。可行的话，使用带有插销防护套且最大规定尺寸及公差+0/-0.06 mm 以及标称插销间距公差+0.05/0 mm的插头。插销防护套的尺寸必须在相关尺寸规范公差以内。
NOTE 3 The shapes of the extremities of the insulating sleeves are not considered of importance for the purpose of the test,
provided that they are according to the relevant standard sheet.
注3︰插头防护套兩端的形狀对本试验來說可以忽略不计，但必须符合有关的标准。
NOTE 4 The material of the brass pins of the test plug  should be as specified in ISO  1639, Type CuZn39Pb2-M, and their
micro-composition should be homogeneous.
注4︰黄铜插销的材料必须为ISO1639规定的CuZn39Pb2-M，且必须为均质材料。
The ends of round pins are rounded.
圆插销的端部应磨圆。
Plugs are tested using a fixed socket-outlet complying with this standard and having as near-to-average
characteristics as can be selected.
插头使用一种符合本标准且性能尽量接近平均表现的固定式插座做试验。
NOTE 5 Care should be taken that the pins of the test plug are in good condition before the test is started.
注5︰在开始试验之前注意使试验插头的插销处于良好的狀态。
For accessories with a rated voltage lower than or equal to 250 V and a rated current lower than or equal
to 16 A, the length of the stroke of test apparatus is between 50 mm and 60 mm.
对于额定电压小于等于 250V 及额定电流小于等于 16A 的插接装置，试验装置的冲程为 50mm～
60mm。
NOTE 6 The length of the stroke for accessories with other ratings is under consideration.
注6︰其它额定值的插接装置，冲程距離正在制定中。
The plug is inserted and withdrawn from the socket-outlet 50 times (100 strokes) at a rate of 
将插头插入和拔出插座 50 次（100 个行程） ，插拔的速率为︰
−  30 strokes per minute for accessories having a rated current up to and including 16 A and a rated
voltage up to and including 250 V;
额定电流小于等于 16A、额定电压小于等于 250V 的插接装置，每分钟 30 个行程；
−  15 strokes per minute for other accessories.
其它插接装置，每分钟 15 个行程。
NOTE 7 A stroke is an insertion or a withdrawal of the plug.
注7︰一个行程为插头插入一次或拔出一次。
The test voltage shall be 1,1 times the rated voltage and the test current shall be 1,25 times the rated
current.
试验电压必须等于额定电压的 1.1 倍，试验电流必须等于额定电流的 1.25 倍，
The periods during which the test current is passed from the insertion of the plug until subsequent
withdrawal are as follows:
从插头开始插接至随后拔出之间试验电流流过的时间如下︰
−  for accessories with rated current ≤16 A: 1,5+0.5/0秒
16A 及以下的插接装置：（1.5 +0.5/0）秒
−  for accessories with rated current >16 A: 3+0.5/0秒
16A以上的插接装置：（3+0.5/0）秒
Accessories are tested using an alternating current with cosφ= 0,6±0,05.
插接装置应使用 cosφ=0.6±0.05 的交流电流做试验。
No current is passed through the earthing circuit, if any.
电流不流过接地回路。
The test is made with the connections shown in figure 17. Two-pole accessories with neutral contact (2P
+ N and 2P + N+〒) are connected to two phases and the neutral of a threephase system.
