Scope of application: This part of GB 13140 is applicable to connecting devices used as independent units for household and similar purposes. The AC rated voltage of these connecting devices should not exceed 1000 V and the frequency should not exceed 1000 Hz; The rated DC voltage should not exceed 1500 V; Electrically, it should be possible to connect two or more hard copper wires (solid or stranded) or soft copper wires with a cross-sectional area of 0.2 mm~35 mm '(including 35 mm') or corresponding AWG wire specifications. These hard or soft copper wires should comply with the requirements of GB/T 3956-2008 or GB/T 18213-2000. Note. For wires with a rated connection capacity less than 0.5 mm, refer to GB/T 18213-2000, and for wires with a rated connection capacity greater than or equal to 0.5 mm, refer to GB/T 3956-2008. Except for twisted connection devices and insulated connectors with piercing, connectors that meet the requirements of this section should not require the use of special tools for connection. This section is a general requirement, It should be used in conjunction with Part 2 Special Requirements (hereinafter referred to as "Part 2"): - Devices with threaded clamping pieces (GB 13140.2) - Devices with unthreaded clamping pieces (GB 13140.3> - Connecting devices with piercing insulation clamping pieces (GB 13140.4) - Devices with twisted connections (GB 13140.5) Test standards: GB/T 2423.8-1995 Environmental testing for electrical and electronic products, Part 2: Test methods, Test Ea: Free fall (IEC 60068-2-32:1990,1DT) GB/T 2423.55-2006 Environmental Testing for Electrical and Electronic Products - Part 2: Test Methods - Test Eh: Hammer Impact Test (IEC 60068-2-75:1997.
