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 33.Particular requirements for commercial electric deep fryers
1 Scope
This chapter of GB/T 4706.1-2024 is replaced by the following.
This document covers commercial electric fryers and deep fryers not intended for household use with a pressure not exceeding 50 kPa and a pressure vessel volume not exceeding.200 L.
For single-phase appliances connected to a phase and neutral line, the rated voltage shall not exceed 250V, and other appliances shall not exceed
Over 480V.

The electrical parts of appliances using other forms of energy are also within the scope of this document.
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 equipment intended for use on vehicles, ships or aircraft, necessary additional requirements are permitted;
--- The relevant national management departments may impose additional requirements on the equipment;
--- The relevant national management departments have stipulated additional requirements for pressure equipment.
