The previous versions of this document and the documents it replaces are as follows. ---First issued in.1999 as GB 4706.43-1999, first revised in.2005; ---This is the second revision.IntroductionGB/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. GB/T 4706 consists of several parts. The first part is general requirements, and the other parts are special requirements. For products covered by special requirements, their safety requirements are the same as general requirements. The special requirements are used in conjunction with the general requirements, which include supplements and modifications to the corresponding clauses in the general requirements to provide Complete product requirements. This document is the protection requirements for electrical, mechanical, thermal, fire and radiation risks that the appliance should have when used normally in accordance with the instructions for use. 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 respective functions as long as it is reasonable. For each function of the appliance, if applicable, the effect of one function on other functions shall be considered. 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 revises GB/T 4706.43-2005 and adopts the structure of IEC 60335.It is consistent with GB/T 4706.1-2024 "Household and similar appliances" "Safety of electrical appliances for similar purposes Part 1.General requirements" is used in conjunction with this document. The parts marked "applicable" in this document indicate The corresponding clauses in GB/T 4706.1-2024 "Safety of Household and Similar Electrical Appliances Part 1.General Requirements" apply to this document; For the part of this document marked as "replacement", the terms in this document shall prevail; for the part of this document marked as "addition", it means that in addition to complying with In addition to the corresponding clauses in GB/T 4706.1-2024, the additional clauses in this document must also be complied with; the parts of this document marked as "modified" It means that the corresponding clauses of GB/T 4706.1-2024 are modified.
