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 GB/T 4706.1-2024 "Safety of Household and Similar Electrical Appliances - Part 1: General Requirements" the corresponding clauses in the "Requirements" shall apply to this document; for the parts marked "replace" in this document, the clauses in this document shall prevail;

The "Add" part indicates that in addition to complying with the corresponding clauses in GB/T 4706.1-2024, the additional clauses in this document must also be complied with.

Clause; The part marked "modified" in this document indicates that the corresponding clauses of GB/T 4706.1-2024 are modified.

Safety of household and similar electrical appliances Part 95: Particular requirements for commercial electric range hoods

1 Scope

This chapter of GB/T 4706.1-2024 is replaced by the following.

This document specifies the installation of commercial cooking appliances such as stoves, single and double-sided griddles and deep fryers, not intended for household use.

Safety requirements for electric range hoods.

This document is applicable to single-phase range hoods connected to one phase line and one neutral line, with a rated voltage not exceeding 250V.

The rated voltage shall not exceed 480V.

This document also applies to stand-alone complete units and cooker hoods assembled into a whole from separate components (including a fan).

The following systems are also included.

---Rear ventilation system;

--- Downdraft ventilation system;

---Smoke exhaust module.

NOTE 101 Scope hoods are used in kitchens such as restaurants, food shops, hospitals and in commercial enterprises such as bakeries and butchers.

The range hood can be used above one or more different or the same types of appliances.

As far as is practical, this document deals with the common hazards arising from this type of apparatus.

Note 102.Pay attention to the following.

--- For range hoods intended for use on vehicles, ships or aircraft, there are necessary additional requirements;

--- In many countries, relevant health care departments, labor protection departments, water supply management departments and similar departments have regulations on the safe use of appliances.

Additional requirements were set;

--- For cooker hoods equipped with a filter system with an ionized air device, IEC 60335-2-65 is also applicable.

Note 103.This document does not apply to.

--- Household range hoods (IEC 60335-2-31);

--- Special purpose range hoods, this document is used as a guide (range hoods constructed on site in the factory or specially constructed and not mass-produced);

--- Range hoods without fans;

--- Range hoods designed for industrial use;

--- Range hoods used in places with special conditions such as corrosive or explosive air (dust, steam or combustible gas).

NOTE 104 Requirements for range hoods with externally mounted fans are under consideration.
