插头插座量规Gauges for plugs and sockets：
IEC60884|GB2099|VDE0620 测试设备Testing equipments：
Accessories shall be so constructed that they comply with the following temperature-rise test.
Non-rewirable accessories are tested as delivered.
Rewirable accessories are fitted with polyvinyl chloride insulated conductors having a nominal
cross-sectional area as shown in table 15.
可拆线插接装置应接上表 15 所示标称截面积的聚氯乙烯 PVC 绝缘线。
The terminal screws or nuts are tightened with a torque equal to two-thirds of that specified in 12.2.8.
端子螺丝或螺帽必须用 12.2.8 规定扭矩的 2/3 拧紧。
NOTE 1 To ensure normal cooling of the terminals, the conductors connected to them should have a length of at least 1 m.
Flush-mounted accessories are mounted in flush-mounted boxes. The box is placed in a block of
pinewood filled around the box with plaster, so that the front edge of the box does not protrude and is not
more than 5 mm below the front surface of the pinewood block.
NOTE 2 The test assembly should be allowed to dry for at least seven days when first made.
The size of the pinewood block, which may be fabricated from more than one piece, shall be such that
there is at least 25 mm of wood surrounding the plaster, the plaster having a thickness between 10 mm
and 15 mm around the maximum dimensions of the sides and rear of the box.
NOTE 3 The sides of the cavity in the pinewood block may have a cylindrical shape.
The cable(s) connected to the socket-outlet shall enter through the top of the box, the point(s) of entry
being sealed to prevent the circulation of air. The length of each conductor within the box shall be (80 ±
Surface-type socket-outlets shall be mounted centrally on the surface of a wooden block, which shall be
at least 20 mm thick, 500 mm wide and 500 mm high.
明装插座必须固定在硬木块表面的中心，该木块至少厚 20mm、宽 500mm和高 500mm。
Other types of socket-outlets shall be mounted according to the manufacturer's instruction or, in the
absence of such an instruction, in the position of normal use considered to give the most onerous
The test assembly shall be placed in a draught-free environment for the test.
Socket-outlets are tested using a test plug with brass pins having the minimum specified dimensions. For
this test, the temperature rise is measured on the terminals. (2006-05 amended)
The plug shall be tested in a draught-free environment at the centre of a plane wooden sheet which shall
be at least 20 mm thick, 500 mm wide and 500 mm high. (2006-05 amended)
插头必须在一个不通风环境，放在至少厚 20mm、宽 500mm和高 500mm的平面厚木块中央测试。
Plugs are tested as follows. (2006-05 amended)
Clamping units having the dimensions specified in Figure 44 are fitted on each live pin and earthing pin, if
any, of the plug together with the thermocouple. The screw is then placed approximately in the middle of
the bare part of the pin and tightened with a torque of 0,8 Nm. (2006-05 amended)
如图 44设定尺寸的夹紧单元将热电耦固定在带电插销及地线插销上。螺丝以 0.8Nm扭距大约固
An alternating current as specified in Table 20 is then passed for 1 h. (2006-05 amended)
施加表 20 规定的交流电 1 小时。(2006-05 修订)
Plugs having lateral earthing contacts and resilient earthing contacts are tested using a fixed
socket-outlet complying with this standard and having as near to-average characteristics as can be
selected, but with minimum size of the earthing pin, if any. (2006-05 amended)
The plug is inserted into the socket-outlet, and an alternating current as specified in Table 20 is passed
for 1 h. (2006-05 amended)
将插头插入插座中，施加表 20 规定的交流电 1 小时。(2006-05 修订)
NOTE 4 Adequate measures should be taken to avoid electric shocks during the test. (2006-05 amended)
For accessories having three poles or more, the current during the test shall be passed through the phase
contacts, where applicable. In addition, separate tests shall be made passing the current through the
neutral contact, if any, and the adjacent phase contact and through the earthing contact, if any, and the
nearest phase contact. For the purpose of this test, earthing contacts, irrespective of their number, are
considered as one pole.
In the case of multiple socket-outlets, the test is carried out on one socket-outlet of each type and current
The temperature is determined by means of thermocouples. (2006-05 amended)
The temperature rises indicated by the thermocouples shall not exceed 45 K. (2006-05 amended)
透过热电耦显示的温升不得超过 45K。(2006-05 修订)
NOTE 5 For the purpose of the test of 25.3, the temperature rise of external parts of insulating material not necessary to retain
current-carrying parts and parts of the earthing circuit in position, even though they are in contact with them, is also
NOTE 6 In the case of accessories incorporating dimmers, fuses, switches, energy regulators, etc., these other elements are
short-circuited for the purpose of this test.
