4 Technical requirements
4.1 General
4.1.1 Single phase plugs and socket-outlets for household and similar purposes are divided into two basic types—no earthing at two poles and earthing at two poles.
4.1.2 The types, basic parameters and dimensions of single-phase plugs and socket-outlets for household and similar purposes shall be in accordance with the provisions of Figure 1, Figure 2, Figure 3, and Figure 4.
4.2 Plug
4.2.1 The shape of the plug is not specified, but the distance of the live plugs and pins to the edge shall not be less than 6.5 mm.
Note: The edge of a non-level plug insertion surface is determined as follows: suppose a plane vertical to the axis of the plug pin moves 1 mm from the insertion surface towards the plug body, and the intersecting boundary line of this plan with the exterior surface of the plug body is considered the edge of the plug, as shown in value B of Figure 5.
4.2.2 The live pin of the plug may have an insulating sheath. For the plug of Figure 1, the height of the insulating sheath is (7±0.5) mm; for the plug of Figure 3, the height of the insulating sheath is (9±0.5) mm, see S in Figure 6. The outer dimension of the plug insulating sheath cannot exceed the minimum dimension of the corresponding socket, and the plug shall be able to insert into the socket-outlet smoothly.
Plugs with insulating sheaths shall also meet the requirements of 4.2.1.
Note: A plug with an insulating sheath may involve patent issues.
4.2.3 Class II device may be equipped with a non-earthing plug of the same type, parameters and dimensions as the single phase dipolar plug with earthing contact shown in Figure 3 In Figure 3, the protective door driving device is installed at the position of the earthing pin, the color of the driving device shall be black, it shall not be connected to the earthing conductor nor marked with the earthing symbols, but only taken as the driving device for opening the protective door during insertion with the socket-outlets.

5 Test methods
5.1.1 To check the dimension of single-phase plugs and socket-outlets for household and similar purposes, use the special gauges specified in Figure 8 to Figure 16 and a vernier caliper with a graduation of 0.02 mm. The dimension of the rounded part of the plug pin end should be measured with an appropriate measuring tool. The surface roughness of these gauges shall uniformly be of Rockwell hardness HRC58~HRC62, the parallelism, perpendicularity and symmetry of the gauges shall be in accordance with the tolerance H level specified in GB/T 1184-1996.
5.1.2 The pin of the plug shall be able to pass the gauges shown in Figure 8 and Figure 9. If the plug pin has an insulating sheath, the insulating sheath does not need to pass the gauges shown in Figure 8 and Figure 9.
5.1.3 The socket gauges are used as follows:
——The socket go gauge shall be able to be inserted into the socket on the socket-outlet panel;
——The socket no-go gauge shall not be inserted into the socket of the socket-outlet panel;

When using gauges, if the socket-outlet has a protective door, it shall be disabled to avoid affecting the test.
The insertion force of the gauge shall not be greater than the maximum extraction force in Table 16 of GB/T 2099.1-2021.
