The terms and definitions defined in GB/T 2900.70-2008 and GB/T 2099.1-2021, and the following are applicable to this document.

4 Technical Requirements

5 Test Methods

5.1 For the inspection of the dimensions of single-phase plugs and socket-outlets for household and similar purposes, the special-purpose measuring gauges specified in Figure 12 ~ Figure 14, Figure 16 ~ Figure 25, and a vernier caliper with a division value not greater than 0.02 mm shall be used. The dimensions of the rounded part at the end of the plug pin shall be measured with an appropriate measuring instrument. The surface roughness of these measuring gauges is all Ra 0.8, and the hardness is Rockwell hardness HRC58 ~ HRC62. The geometric tolerances of the measuring gauges, such as: parallelism, perpendicularity and symmetry, shall comply with the tolerance level H specified in GB/T 1184-1996. For the plugs of the direct plug-in equipment, in accordance with the manufacturer’s instructions, under the most unfavorable situation, directly insert the direct plug-in equipment into the socket-outlet. After it stabilizes, measure the length of the pin. 5.3 Use 3 new plug samples to conduct the pin bending test in accordance with the following method. a) After the finished plug sample is clamped by a rigid stationary fixture, apply a force to the pin to cause it to bend (as shown in Figure 26). b) Before starting the test, the pin shall be straight. If there is any doubt whether the pin is straight enough, the corresponding measuring gauges in Figure 16, Figure 17 and Figure 18 can be used to check it. e) For phase line pins and neutral line pins, the test force shall be applied toward the center point of the plug, then, return to the initial position. ± 0.3) mm, then, push the pin back to the starting point. Any “bounce” can be ignored. g) From the starting point of the displacement to the end point (7.5 mm ± 0.3 mm), then, back to the starting point is one cycle (that is, one cycle is equal to two separate bending and normalizing movements). i) There shall be at least 10 s interval between each cycle. l) After the test, check the pin with normal or corrected t normal vision. may hold the broken pins together and maintain electrical contact. 5.4 After normally inserting the direct plug-in equipment into the socket-outlet, use the steel probe shown in Figure 10 of GB/T 2099.
