Introduction
GB/T 4706, "Safety of Household and Similar Electrical Appliances," largely adopts IEC 60335.Based on this, GB/T 4706 references...
The structure of IEC 60335 is divided into several parts, consisting of general requirements and special requirements. Part 1 contains the general requirements, and the other parts...
For special requirements. For products covered by special requirements, the safety requirements are the general requirements combined with these special requirements, and the specific requirements are applied in conjunction with the general requirements.
The requirements include supplements and modifications to the corresponding clauses in the general requirements to provide complete requirements for each product.
This document outlines the protective measures required for appliances when used normally according to the instructions, addressing risks related to electrical, mechanical, thermal, fire, and radiation.
This document also includes information on abnormal situations that may occur during use, and considers the impact of electromagnetic interference on the safe operation of the equipment.
This document takes into account the requirements specified in GB/T 16895 "Low-voltage electrical installations", and the appliances shall comply with electrical wiring rules when connected to the power supply.
The requirements are consistent and coordinated.
This document provides safety requirements for DC household appliances. If multiple functions of an appliance involve other parts of GB/T 4706, then...
As long as it is reasonable, the other parts can be applied to each function of the appliance. If applicable, the impact of one function on other functions must be considered.
Note. For example, when the appliance is a DC household air conditioner, this document is consistent with GB/T 4706.1-2024 "Safety of household and similar electrical appliances - Part 1.Communication".
Requirements for use in household and similar electrical appliances - Part 32.Particular requirements for heat pumps, air conditioners and dehumidifiers
Used in conjunction with other products.
GB/T 4706.1 applies when no additional requirements are given in other parts for hazards already included in this document.
GB/T 4706 (all parts) is a standard relating to appliance safety and takes precedence over general/horizontal standards that cover the same topic.
This document is used in conjunction with GB/T 4706.1-2024.The parts in this document that specify "Applicable" indicate that GB/T 4706.1-2024 applies.

The part marked "modified" indicates that modifications have been made to the corresponding clauses of GB/T 4706.1-2024.
Safety of household and similar electrical appliances
Part 129.Special Requirements for DC Household Appliances
1 Scope
The relevant chapter in GB/T 4706.1-2024 is replaced by the following content.
This document specifies the safety requirements for DC household appliances (hereinafter referred to as "appliances").
This document applies to appliances powered by DC and with a rated voltage not exceeding 750V DC.
Note 101.The DC power supply involved in this document falls into the following categories.
---Directly powered by the DC mains, for example, by DC 375V or DC 48V;
---Powered by DC output from external batteries, photovoltaic systems, etc.
This document also applies to appliances that are not intended for general household use but may still pose a danger to the public, such as those intended for use in shops or light industrial settings.
Equipment used by non-professionals in industry and farms.
Note 102.Examples of such appliances include. commercial catering equipment and cleaning appliances, as well as appliances used in barbershops.
The reasonably foreseeable dangers posed by the various appliances discussed in this document are those that everyone would encounter. However, in general, this document...
The item was not considered.
---The following groups (including children).
● Due to physical, sensory, or mental impairments, or
● Due to a lack of experience and knowledge,
This results in situations where the user is unable to use the equipment safely when unattended or without guidance;
