This Part is Part 2 of GB/T 4343. This Part was drafted as per the rules of GB/T 1.1-2009. This Part replaced GB/T 4343.2-2009 Electromagnetic Compatibility - Requirements for Household Appliances, Electric Tools and Similar Apparatus - Part 2.Immunity. Compared with GB/T 4343.2-2009, the major technical changes of this Part are as follows. --- 5.1.For electrostatic testing on connecting plugs and sockets ("4kV contact discharge shall be applied to conductive and accessible parts. For example, metal contacts in battery compartments or sockets are excluded."), it indicates that there is no need to test the contact. GB/T 17626.2-2018 includes detailed instructions on how to handle electrostatic discharge (ESD) on contacts and other surfaces. At the same time, the basic standard GB/T 17626.2-2018 requires discharge on the horizontal coupling plate (HCP) and vertical coupling plate (VCP). --- 5.3 and 5.4.According to GB/T 17626.6-2017, the DC power port test table is aligned with the general standard, and it is the same for 5.3 and 5.4. --- 5.3 and 5.4.For EUTs that use single-wire cables and no other cables, use the test setup shown in Figure 2.The settings described in Annex F of GB/T 17626.6- 2017 shall not be used. --- 5.5.GB/T 17626.22-2017 works as an alternative method of radiated immunity test. --- 5.6.Line-to-ground surge is not applicable to products that are not grounded. This Part uses the translation method to equivalently adopt CISPR 14-2.2015 Electromagnetic Compatibility – Requirements for Household Appliances, Electric Tools and Similar Apparatus – Part 2.Immunity – Product Family Standard. The Chinese documents that have a consistent correspondence with the international documents cited in this Part are as follows. --- GB/T 4365-2003 Electrotechnical Terminology - Electromagnetic Compatibility [IEC 60050(161).1990, IDT] This Part made the following editorial modifications. --- Change the standard name into Electromagnetic Compatibility Requirements for Household Appliances, Electric Tools and Similar Apparatus – Part 2.Immunity. --- Add the “Bibliography”. This Part was proposed by and under the jurisdiction of National Technical Committee on Radio Interference of Standardization Administration of China (SAC/TC 79). Drafting organizations of this Part.
