GB/T 4706 "Safety of Household and Similar Electrical Appliances" adopts most of IEC 60335.On this basis, GB/T 4706 refers to The structure of IEC 60335 is divided into several parts, consisting of general requirements and special requirements. Part 1 is general requirements, and the other parts are For products covered by special requirements, their safety requirements are general requirements used in combination with the special requirements. The requirements include supplements and modifications to the corresponding clauses in the general requirements to provide complete requirements for each product. This document is the protection requirements for electrical, mechanical, thermal, fire and radiation risks when the appliance is used normally in accordance with the instructions. This document also covers abnormal conditions that may occur during use and considers how electromagnetic interference may affect the safe operation of the equipment. This document has taken into account the requirements specified in GB/T 16895 "Low Voltage Electrical Installations". The appliance is connected to the power supply in accordance with the electrical wiring rules. requirements are coordinated. If multiple functions of an appliance involve other parts of GB/T 4706, the other parts shall apply to the appliance separately as long as it is reasonable. Each function. If applicable, consider the impact of one function on other functions. When no additional requirements are given in other parts for hazards already included in this document, GB/T 4706.1 applies. GB/T 4706 is a standard covering appliance safety and takes precedence over general standards/horizontal standards covering the same subject. This document is used in conjunction with GB/T 4706.1-2024 "Safety of Household and Similar Electrical Appliances Part

1.General Requirements". The part marked "applicable" in the document indicates that GB/T 4706.1-2024 "Safety of Household and Similar Electrical Appliances - Part

1.General Requirements" The corresponding clauses in the "Requirements" shall apply to this document; for the parts marked "replace" in this document, the clauses in this document shall prevail; The "Add" part indicates that in addition to complying with the corresponding clauses in GB/T 4706.1-2024, the additional clauses in this document must also be complied with.

Safety of household and similar electrical appliances Part 113: Particular requirements for wireless power supply equipment

1 Scope

GB/T 4706.113-2024 is Part 113 of the Chinese household appliance safety series and covers wireless power appliances - inductive charging pads, in-furniture chargers and the transmitters built into kitchen surfaces. They raise hazards the general standard did not anticipate: a coin or key left on the pad heats without limit through induced eddy currents, the coupling changes if the receiver is misplaced, and the field itself must be limited for the people around it. The standard follows the clause structure of the general safety standard, setting the particular requirements for marking and instructions, protection against access to live parts, input and current, heating, leakage current and electric strength at operating temperature and after humidity, transient overvoltage, moisture resistance, transformer overload protection, abnormal operation, stability, mechanical strength, construction, internal wiring, components, terminals, earthing, creepage distances and resistance to heat and fire. It takes effect on 1 August 2026.

This chapter of GB/T 4706.1-2024 is replaced by the following. This document covers household and similar appliances with a rated voltage not exceeding 250 V for single-phase appliances and 480 V for other appliances Safety of wireless power devices for various purposes. Appliances not intended for normal household use but which may nevertheless present a danger to the public, e.g. those intended to be used by non-professionals in shops, in light industry or on farms. Appliances used by professionals also fall within the scope of this document. Note
