Introduction
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. 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 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.
For the parts marked as "added" in this document, in addition to complying with GB/T 4706.1-2024, the provisions in this document shall prevail.
In addition to the corresponding clauses, the clauses added in the clauses of this document must also be complied with; the part of this document marked "modified" means that in GB/T 4706.1-
The relevant provisions of 2024 will be modified.
Safety of household and similar electrical appliances
Part 18.Particular requirements for battery chargers
1 Scope
This chapter of GB/T 4706.1-2024 is replaced by the following content.
This document specifies the safety requirements for battery chargers for household and similar use.
This document applies to household and
Similar purpose battery charger.
Battery chargers intended to charge batteries in appliances used at home but not within the scope of the GB/T 4706 series of standardization documents
device, also applies to this document.
The requirements for battery chargers used by children aged not less than 8 years without supervision are given in Annex AA.
Battery chargers not intended for general household use but which may nevertheless constitute a source of danger to the public, e.g. intended for use in garages, shops, light industry
and battery chargers for farm use are within the scope of this document.
This document deals with common hazards encountered by all persons in and around the home and presented by appliances. However, in general
The following situations are not considered in this document.
---The following groups (including children).
● has a physical, sensory or mental impairment; or
● Lack of necessary experience and knowledge.
This results in them being unable to use the equipment safely without supervision or instruction.
---Children playing with utensils.
Note 101.Pay attention to the following.
--- For equipment intended for use in vehicles, ships or aircraft, some additional requirements may be required;
--- National management departments may impose additional requirements on equipment.
Note 102.This document does not apply to.
--- Built-in battery chargers, except battery chargers installed in caravans and similar vehicles;
--- The battery charger forms an integral part of the appliance and the battery of the appliance is not accessible to the user;
--- Battery chargers intended for industrial use only;
--- Battery chargers intended for use in special locations, such as locations where corrosive and explosive gases (dust, steam or methane) are present;
--- Battery charger for emergency lighting (GB/T 7000.222);
---Power supply unit for electronic equipment.
