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.

Part 89.High-pressure cleaners and
Particular requirements for steam cleaners
1 Scope
This chapter of GB/T 4706.1-2024 is replaced by the following.
This document specifies the safety requirements for high pressure cleaners. This document applies to high pressure cleaners with a rated pressure of not less than 2.5 MPa and not more than 35 MPa
Appliances without traction drive for domestic and commercial indoor or outdoor use.

If the pressure exceeds 2.5 MPa, the product of capacity and rated pressure shall not exceed 5 MPa·L.
They are not equipped with traction drives. The power system of the high-pressure pump drive consists of the following.
--- The rated voltage of the motor for single-phase appliances shall not exceed 250V, and the rated voltage of other appliances shall not exceed 480V;
---Battery-driven motors;
---internal combustion engine;
---Hydraulic or pneumatic motor.
This document does not apply to the following situations.
--- High-pressure water jetting machines with a rated pressure exceeding 35 MPa;
NOTE 101 In Europe, these appliances are covered by EN 1829-1.
---Household steam cleaners (IEC 60335-2-54);
--- Hand-held and mobile electric tools [IEC 60745 (all parts), IEC 61029 (all parts), IEC 62841 (all parts)
point)];
--- Medical devices [IEC 60601 (all parts)];
