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 the corresponding clauses in GB/T 4706.1-2024 are applicable to this document; the part marked "replaces" in this document indicates that the corresponding clauses in GB/T 4706.1-2024 are applicable to this document.
