The main differences between the new GB4343.1 standard and the GB4343.1:2009 version [Copy link]

GB 4343.1 is a standard for protecting the electromagnetic environment. Its purpose is to establish a unified requirement for the radio disturbance level of household appliances, power tools, electric and electronic toys and similar appliances, determine the disturbance limit, describe the measurement method and standardize the analysis of operating conditions and results. The revised GB4343.1 is equivalent to CISPR 14-1:2011. The main differences between GB4343.1-201X and GB4343.1-2009: - Chapter 1.1, adding appliances and mains-powered and battery-powered dual-power supply equipment realized by the RF generator of the induction cooker; - Adding reference standards GB/T6113.104-2008 Specification for radio disturbance and immunity measuring equipment and measurement methods Part 1-4: Radio disturbance and immunity measuring equipment auxiliary equipment radiated disturbance (CISPR 16-1-4:2007, IDT) in the normative reference documents - GB/T 6113.203-2008 Specification for radio disturbance and immunity measuring equipment and measurement methods Part 2-3: Radio disturbance and immunity measurement methods radiated disturbance measurement (CISPR 16-2-3:2006, IDT) 04 GB/T 6113.402-2006 Specification for radio disturbance and immunity measuring equipment and methods Part 4-2: Uncertainty, statistics and limit modeling Uncertainty of measuring equipment and facilities (CISPR 16-4-2:2003, IDT); - Due to the changes in the standard system and the formulation and revision of the corresponding CISPR16 standard in my country, all CISPR16 standards in this part have been re-referenced; - Chapter 3.24, the definition and description of clock frequency; 07 3.25, the definition and description of battery-powered equipment; - Chapter 3.26, the definition and description of mains-powered equipment; - Delete Table 3 in GB 4343.1-2009, and add Table 2b and 4.1.2.2; - Chapter 4.1.2.3 adds the application of limits for mains-powered equipment and battery-powered equipment; Chapter 6.2.1 adds the layout requirements for the measurement procedure on the power lead; Chapter 7.2.2 adds the operating conditions for battery-powered equipment; Chapter 7.3.1.3 adds the description of the operating conditions for coffee grinders and coffee machines; Chapter 7.3.4.15 adds the description of the operating conditions for rice cookers; Modify 7.3.6.1, add "Class C toys should meet the 30MHz-1000MHz limit requirements" and "4.1.2.2 (radiated disturbance)" Modify 7.3.7, note: the limits in the frequency band of 30MHz to 1000MHz are not applicable to the devices mentioned in 7.3.7.1 to 7.3.7.3, which only cause intermittent disturbance (see 4.2.1); - Add the title of 7.4.1.6 "The limits of radiated emissions apply to the frequency band of 30MHz to 1000MHz"; - Add the assessment method of assessment in 8.3.1; - Modify 8.3.2 and re-describe some methods; - Add "9 Measurement method of radiated emission (30MHz to 1000MHz)" and "10 Measurement uncertainty". - Added Figures 10 and 11; - Added Appendix B Requirements for Induction Cookers; - Added three references.
