Compared with GB 4706.58-2010, in addition to structural adjustments and editorial changes, the main technical changes are as follows.
--- Added the content that the equipment should be marked with (see 7.1);
--- Increased temperature rise requirements under abnormal working conditions (see 19.101);
--- Increased the number of working cycles of voltage-maintained non-self-resetting thermal circuit breakers (see 24.1.4).
This document is modified to adopt IEC 60335-2-66.2012 "Safety of Household and Similar Electrical Appliances Part 2-66.Waterbed Heaters
Special Requirements.
The technical differences between this document and IEC 60335-2-66.2012 and their reasons are as follows.
--- Changed the category of electric shock protection from "the rated voltage of Class III appliances shall not exceed 24V" to "In terms of electric shock protection, the device
The rated voltage of Class III appliances should not exceed 24V to suit my country's national conditions (see 6.1,
IEC 60335-2-66.2012, 6.1);
--- Deleted "22.102 Class I appliances with grounded metal mesh shall use additional insulation between the metal mesh and the accessible surface".
The Class I appliances described in this article are not applicable to my country (see 22.102 of IEC 60335-2-66.2012).

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. 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.
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 58.Particular requirements for waterbed heaters
1 Scope
This chapter of GB/T 4706.1-2024 is replaced by the following.
This document specifies the safety requirements for waterbed heaters.
This document applies to waterbed heaters and their associated control components for household and similar purposes with a rated voltage not exceeding 250V.
Appliances that are not intended for general household use but may still cause danger to the public, such as appliances intended for use in hotels, also belong to this document
range.
This document deals with appliances that present common hazards that are encountered by all people in the home and its surroundings.
However, in general, this document does not cover.
---People (including children) due to.
● physical, sensory or mental impairment, or
● Lack of experience and knowledge,
Hazards when using appliances safely without supervision or instruction;
--- Condition of children's play equipment.
Note 101.Pay attention to the following.
--- For equipment intended for use in vehicles, ships or aircraft, some additional requirements may be required;
--- National authorities may impose additional requirements on equipment.
Note 102.This section does not apply to.
--- Medical devices [see IEC 60601 (all parts)];
---Utensils used for immersion in water.
