This document is Part 1 of GB/T 21437 “Road vehicles - Test method of electrical disturbances from conduction and coupling”. GB/T 21437 has issued the following parts. - Part 1.Definitions and general considerations; - Part 2.Electrical transient conduction along supply lines only; - Part 3.Electrical transient transmission by capacitive and inductive coupling via lines other than supply lines. This document replaces GB/T 21437.1-2008 “Road vehicles - Electrical disturbances from conduction and coupling -Part 1.Definitions and general considerations”. Compared with GB/T 21437.1-2008, in addition to structural adjustments and editorial modifications, the main technical changes in this document are as follows. - Added GB/T 29259 as a reference; Deleted the duplicate terms and definitions with GB/T 29259 (see Chapter 3); - Added general test conditions (see Chapter 5); - Added functional characteristic state classification (FPSC) (see Annex A). The modification of this document adopts ISO 7637-1.2015 “Road vehicles - Electrical disturbances from conduction and coupling - Part 1.Definitions and general considerations”. The technical differences between this document and ISO 7637-1.2015 and the reasons are as follows. - To maintain the unity of the expression and understanding of the functional characteristic status classification (FPSC) among the electromagnetic immunity series standards, it is changed to refer to Annex A of GB/T 33014.1-2016; - Change the normative reference "IEC 60050-151" in Chapter 3 of ISO 7637-1.2015 to "GB/T29259", so as to avoid repetition; Deleted the terms and definitions in ISO 7637-1.2015 that are repeated with GB/T 29259. Attention is drawn to the possibility that some of the elements of this Standard may be the subject of patent rights. The issuing authority shall not be held responsible for identifying any or all such patent rights.
