3 Foreword All the technical contents of this Part are mandatory. GB 4343 Electromagnetic compatibility requirements for household appliances, electric tools and similar apparatus consists of two parts: - Part 1: Emission; - Part 2: Immunity (GB/T ). This Part is Part 1 of GB This Part is drafted in accordance with the rules given in GB/T This Part replaces GB Electromagnetic compatibility - Requirements for household appliances, electric tools and similar apparatus - Part 1: Emission. Compared with GB , the main technical content changes of this Part are as follows: - In the scope, ADD appliances whose main functions are performed by RF generators used in induction cooking appliances, and it is clear that both mains-operated appliances and battery-operated appliances are included in the scope of use of this Part (see 1.1); - MODIFY the definition of 3.13 battery box, and ADD the definitions of 3.24 clock frequency, 3.25 battery-operated appliance, 3.26 mains-operated appliance (see Clause 3); - ADD Table 2b -- Margin when performing disturbance power measurement in the frequency range 30 MHz to 300 MHz, and MODIFY Table 3 -- Radiated disturbance limits and testing methods for the frequency range 30 MHz to MHz; - MODIFY , giving the application of the limits of mains-operated appliances and battery-operated appliances; - MODIFY 6.2.1, re-descripting the measurement procedure on the mains lead; - MODIFY 7.2.2, re-descripting the operating conditions of battery-operated appliances; - MODIFY , adding the detailed operating conditions of coffee grinders and coffee makers; Buy True-PDF Auto-delivery.

4 - ADD , specifying the operating conditions of rice cookers; - ADD , indicating that the radiated emission limits apply throughout the frequency range from 30 MHz to MHz; - ADD 8.3.1, introducing the statistical method for tests based on a general margin to the limit; - MODIFY 8.3.2, changing the statistical method for tests based on the noncentral t-distribution; - ADD Clause 9 -- Methods of measurement of radiated emission (30 MHz to MHz) and Clause Measurement uncertainty; - ADD Figure 10 and Figure 11; - ADD Annex B -- Requirements for induction cooking appliances. This Part uses the translation method to identically adopt CISPR 14-1:2011 Electromagnetic compatibility - Requirements for household appliances, electric tools and similar apparatus - Part 1: Emission. The Chinese documents that have a consistent correspondence with the international documents normatively referenced in this Part are as follows: - GB Safety of household and similar electrical appliances - Particular requirements for electric fence energizers (IEC :2006, IDT); - GB/T Specification for radio disturbance and immunity measuring apparatus and methods - Part 1-1: Radio disturbance and immunity measuring apparatus - Measuring apparatus (CISPR :2010, IDT); - GB/T Specification for radio disturbance and immunity measuring apparatus and methods - Part 1-2: Radio disturbance and immunity measuring apparatus - Ancillary equipment - Conducted disturbances (CISPR :2006, IDT); - GB/T Specification for radio disturbance and immunity measuring apparatus and methods - Part 1-4: Radio disturbance and immunity measuring apparatus - Antennas and test sites for radiated disturbance measurements (CISPR :2012, IDT); - GB/T Specification for radio disturbance and immunity measuring apparatus and methods - Part 2-1: Methods of measurement of disturbances and immunity - Conducted disturbance measurements Buy True-PDF Auto-delivery.

6 Electromagnetic compatibility requirements for household appliances, electric tools and similar apparatus - Part 1: Emission 1 Scope 1.1 This Part applies to the conduction and radiation of radio-frequency disturbances from appliances whose main functions are performed by motors, switching or regulating devices, or by RF generators used in induction cooking appliances. It includes such equipment as: household electrical appliances, electric tools, regulating controls using semiconductor devices, motor-driven electro-medical apparatus, electric/ electronic toys, automatic dispensing machines as well as cine or slide projectors. Both mains-operated appliances and battery-operated appliances are included. Also included in the scope of this Part are: - separate parts of the above-mentioned equipment such as motors, switching devices e.g. (power or protective) relays, however no emission requirements apply unless formulated in this Part. Excluded from the scope of this Part are: - apparatus for which all emission requirements in the radio frequency range are explicitly formulated in other national standards; NOTE 1: Examples are: - luminaires, including portable luminaires for children, discharge lamps and other lighting devices: CISPR 15; - audio and video equipment and electronic music instruments, other than toys: CISPR 13 and CISPR 20 (see also ); - mains communication devices, as well as baby surveillance systems: IEC ; - equipment for generation and use of radio frequency energy for heating (other than induction cooking) and therapeutic purposes: CISPR 11; Buy True-PDF Auto-delivery.
