Scope 1.1 This section applies to the electromagnetic immunity of household and similar electrical appliances and similar appliances, electric toys, and electric tools. The rated voltage of single-phase appliances connected to the phase and neutral lines shall not exceed 250 V, and for other appliances, it shall not exceed 480 V. The appliance can be equipped with an electric motor, an electric heating element, or both, and can include electrical or electronic circuits. It can be powered by mains power, transformers, batteries, or other power sources. This section also applies to non household appliances with immunity requirements, such as appliances used by non professionals in shops, light industrial sites, and farms, as long as they are within the scope of GB 4343.1. In addition, it is also suitable for: - microwave ovens for household and dining purposes; -- Cooking stoves and ovens heated by radio frequency energy-- (Single or multiple areas) induction cookers; - personal care appliances equipped with radiators from ultraviolet to infrared (including visible light)-- The power supply and battery charger used or intended for use within the scope of this section. 1.2 This section does not apply to: - lighting equipment; - appliances specifically designed for heavy industry; -- Electrical installation components intended to be fixed on buildings (such as fuses, circuit breakers, cables, and switches)—— Instruments intended for use in special electromagnetic locations, such as in the presence of strong electromagnetic fields (such as near broadcasting stations) or in places where strong pulses are generated by the power grid (such as within power stations); - Radio and television receivers, audio and video equipment, and electronic music devices other than toys-- Medical electrical equipment- Personal computers and similar devices other than toys; - Radio transmitters- Specially designed tools for vehicles-- Infant monitoring system. 1.3 Frequency Range Coverage of Immunity Requirements О Hz~~400 GHz. The impact of electromagnetic phenomena related to equipment safety is not included in the scope of this section, but belongs to other standards, such as the GB4706 series. For abnormal operation of instruments (such as simulated circuit failure operation for experimental purposes), this section does not consider it. Note: Appliances used on ships or aircraft may require additional requirements. The purpose of this section is to specify the immunity requirements for appliances within the scope, including continuous and transient, conducted and radiated electromagnetic disturbances, and electrostatic discharge. These regulations reflect the basic requirements for electromagnetic compatibility immunity. Note: In special circumstances, the disturbance level may exceed the test values specified in this section. In this situation, special mitigation measures may need to be taken
