GB 45833-2025 General safety technical requirements of electricity use for gas-burning appliance
1 Scope
This document specifies the classification of electricity use safety, electrical construction and materials, electrical performance, electromagnetic compatibility safety, remote operation, electrical-related information, and test methods in connection with gas-burning appliances (hereinafter referred to as "gas appliances").
This document is applicable to gas appliances as specified in GB 16914, with a rated voltage not exceeding 250 V.
This document is not applicable to gas appliances that operate solely on batteries, or the integrated parts of integrated gas appliances that rely solely on electrical energy to perform their functions (such as the electric oven in an integration cooking appliance, and the induction cooker in a gas-electric combined stove); nor to gas appliances designed specifically for industrial use or those used in special environments (e.g. environments with corrosive gas).

3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 4706.1 apply.
3.1
program
sequence of operation of a gas appliance
Note 1: The sequence of operation varies depending on the types of gas appliances and may include low power mode, start-up, supervision control and power off, safety shutdown, and lockout.
Note 2: Low power modes include off mode, standby mode, and network mode.

3.2
functional safety
safety assurance capability achieved during correct operation of the safety control device or controller on the gas-burning appliance
[Source: GB/T 30597-2014, 3.22, modified]
3.3
defined state
state in which a gas-burning appliance has the following safety characteristics:
a) The gas-burning appliance passively enters a state in which the gas is cut off, and when the cause of entering this safety state no longer exists, it can only be restarted according to specific requirements;
b) The gas-burning appliance actively performs protective actions within the specified time, executing a safety shutdown or entering a lockout state; and
c) The gas-burning appliance operates normally.

3.4
fault
abnormal condition that may cause a reduction or loss of the capability of a functional unit to perform its required function
[Source: GB/T 20438.4-2017, 3.6.1, modified]
3.5
class I gas-burning appliance
gas-burning appliance that uses basic insulation and additional safety measures for protection against electric shock
Note 1: This protective measure involves connecting accessible conductive parts to the earthing protection conductor in the fixed wiring of the installation to prevent accessible conductive parts from becoming live in the event of failure of the basic insulation.
Note 2: This protective measure includes the protective earthing conductor in the power cord.
3.6
class II gas-burning appliance
gas-burning appliance that uses double insulation or reinforced insulation for protection against electric shock
Note 1: This type of gas-burning appliance has no protective earthing measures or measures depending on installation conditions.
Note 2: Such an appliance may be of one of the following types:
——Gas-burning appliance having a durable and substantially continuous enclosure of insulating material which envelops all metal parts, with the exception of parts, such as nameplates, screws and rivets, which are isolated from live parts by insulation at least equivalent to reinforced insulation. Such a gas-burning appliance is referred to as an insulation-encased class II gas-burning appliance.
——Gas-burning appliance having a substantially continuous, in which double insulation or reinforced insulation is used throughout. This type of gas-burning appliance is referred to as a metal-encased class II gas-burning appliance.
——Gas-burning appliance which is a combination of an insulation-encased class II gas-burning appliance and a metal-encased class II gas-burning appliance.
Note 3: The enclosure of an insulation-encased class II gas-burning appliance may form a part or the whole of the supplementary insulation or of the reinforced insulation.
3.7
class II construction
part of an appliance for which protection against electric shock relies upon double insulation or reinforced insulation
3.8
class III gas-burning appliance
Gas-burning appliance in which protection against electric shock relies on supply at safety extra-low voltage and in which voltages higher than those of safety extra-low voltage are not generated
3.9
battery-operated gas-burning appliance
gas-burning appliance that can operate on both supply mains and battery power
3.10
stationary gas-burning appliance
gas-burning appliance that is not intended for movement in daily work and that is used in a fixed location
[Source: GB/T 38522-2020, 3.4, modified]
3.11
movable gas-burning appliance
gas-burning appliance which is not a stationary gas-burning appliance
3.12
type Y attachment
method of attachment of the power cord such that any replacement is intended to be made by the manufacturer, its service agent or similar qualified person
