This section specifies the technical requirements for the terminals and heads, structural requirements, mechanical performance, and electrical performance of household and similar appliance sockets. This section only applies to sockets with alternating current, rated voltage not exceeding 250 V, rated current not exceeding 16 A, with or without grounding sockets, embedded or intended to be installed in or fixed to appliances, hereinafter referred to as appliance sockets. For fixed sockets equipped with threaded terminals, the maximum rated current is only 16A. This section does not include the requirements for concealed installation boxes: it only includes the requirements for exposed installation boxes that are necessary for testing sockets. This section also applies to plugs installed in wire assemblies and plugs and mobile sockets installed in wire extension assemblies. This section also applies to plugs and sockets as a component of electrical appliances, unless otherwise specified in relevant electrical standards. This section does not apply to industrial plugs, sockets, and couplers; Appliance coupler; ELV (Extra Low Voltage) uses plugs and fixed or mobile sockets. If it is also intended for fixed devices, the appliance socket should be equipped with a device for fixing to a suitable installation box. The appliance socket is intended to be used in stationary appliances and office equipment, computers, audio-visual camera equipment, range hoods, stoves, and other appliances. If necessary, explain the use of appliance sockets in the standards related to appliances or equipment. The ambient temperature around the appliance socket usually does not exceed 35 ℃, occasionally reaching 40 ℃
