Reference standard explanation

Standard Description

The content of the GB1002-2008 standard for single-phase plugs and sockets for household and similar purposes, including types, basic parameters, and dimensions, is mandatory.

This standard is a revision of GB 1002-1996. From the date of implementation, this standard replaces and abolishes GB 1002-1996 "Types, Basic Parameters and Dimensions of Single phase Plug and Socket for Household and Similar Purposes".

The main differences between this standard and GB 1002-1996 standard are:

Shice Instrument (SHC) provides organization and supply

——Chapter 5 has added the requirement for the distance between the live pole socket sleeve of a single-phase socket and the mating surface;

——Chapter 5 has added requirements for gauge insertion force;

——Chapter 5 has added provisions for the two pole plug type with a rated current of 16A;

——The effective numerical value of the distance tolerance for single-phase plug and socket opening has been simplified from 3 digits to 2 digits;

——The number of inspection gauges has been increased, and the overall tolerance and size of the gauge design have been modified;

——Added pass gauges and small pass gauges for size inspection of single-phase two pole sockets and single-phase two pole grounded sockets;

——Added non-contact specifications for size inspection of single-phase two pole sockets and single-phase two pole grounded sockets;

——Added a single phase two pole dual socket circular plug stop gauge.

This standard only specifies the types, basic parameters, and dimensions of single-phase plugs and sockets for personal use and similar purposes. Its technical requirements and test methods should comply with GB 2099.1-2009.

This standard was proposed by the China Electrical Appliances Industry Association.

This standard is under the jurisdiction of the National Electrical Accessories Standardization Technical Committee (SAC/TC67).

This standard was drafted by China Academy of Electrical Sciences, Hangzhou Hongyan Electric Co., Ltd., Shenzhen Institute of Metrology and Quality Inspection, Beijing Panasonic Electric Co., Ltd., TCL International Electric (Huizhou) Co., Ltd., Shunde Songben Electric Industrial Co., Ltd., Guangdong Langneng Electric Co., Ltd., Tianji Electric (Shenzhen) Co., Ltd., Legrand (Beijing) Electric Co., Ltd., Beijing ABB Low Voltage Electrical Co., Ltd., Guangzhou Electrical Safety Testing Institute, Qisheng Industry (Huizhou) Co., Ltd., Beijing Breakthrough Electric Co., Ltd., and Cixi Bull Electric Co., Ltd.

The main drafters of this standard are Luo Huaiping, Shan Chaolan, Guan Jie, Zhu Hongbin, Wang Kejian, Zhang Wenjie, Chen Beihuang, Zhu Xinjie, An Guilong, Yi Zhong, Liu Liping, Wen Yongcai, Lin Haiqing, Ruan Liping, Tang Yanlan, Sun, Cai Yingfeng, Zhu Songtao, and Yang Zhenjun.

scope of application

This standard specifies the types, basic parameters, and dimensions of single-phase plugs and sockets for household and similar purposes.

This standard is applicable to single-phase plugs and fixed or mobile sockets with an AC frequency of 50Hz, a rated voltage of 250V, and a rated current not exceeding 16A used in households and similar household environments.

Technical requirements and testing methods

The technical requirements and test methods for single-phase plugs and sockets for household and similar purposes shall comply with the provisions of GB 2099.1.

Type, basic parameters, and dimensions

1. Single phase plugs and sockets for household and similar purposes are divided into two basic types: two pole ungrounded and two pole grounded.

2. The form, basic parameters, and dimensions of single-phase plugs and sockets for household and similar purposes shall comply with the provisions of Figures 1-5 and Tables 1-5.

3. Check the dimensions of single-phase plugs and sockets for household and similar purposes, using the gauges specified in Figures 6-18 and Tables 6-18, and a vernier caliper with a division value of 0.02mm. Measure the size of the rounded part of the plug end with an appropriate measuring tool. The insertion force of the gauge should not exceed the pull-out force specified in GB2099.1. The roughness of these gauges is all 0.8um, and the hardness is HRC58~62. The form and position tolerances of the gauges, such as parallelism, perpendicularity, and symmetry, are in accordance with the tolerance level H specified in GB/T 1184.

4. The shape of the plug is not specified, but the distance between the plug pin and the edge should not be less than 6.5mm.

5. The distance between the socket (excluding the grounding socket) in a single-phase socket and the mating surface should not be less than the safe distance. These dimensions should be inspected using the gauges specified in Figure 12, Table 12, Figure 16, and Table 16 respectively.

6. The type, parameters, and dimensions of a single-phase two pole ungrounded plug with a rated current of 16A should be the same as those of a single-phase two pole grounded plug with a rated current of 16A, but it should be made into a non rewirable plug. The grounding pin is located at the protective door drive plate, black in color, does not connect wires, and is not marked with a grounding symbol. It is only used as a driving device to open the protective door when plugged into the socket.
