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 86: Particular requirements for commercial floor treatment machines

This document specifies the safety requirements for commercial powered floor treatment machines for indoor and outdoor use intended for the following purposes.

---scrub;

---Dry or wet vacuuming;

---Polishing and dry sanding;

---Waxing, using sealing products and powder-based detergents;

---Internal combustion engine;

---Main power drive motor, suitable for single-phase appliances with rated voltage not exceeding 250V and other appliances with rated voltage not exceeding 480V appliance;

---Battery-driven motor.

Battery-operated appliances are equipped with a built-in battery charger.

This document does not apply to.

---Household vacuum cleaners and water-absorbing cleaning appliances (GB/T 4706.7);

---Household floor treatment appliances (GB/T 4706.57);

--- Commercial spray suction apparatus (GB/T 4706.87);

--- Wet and dry commercial vacuum cleaners (including power brushes) (GB/T 4706.93);
