This Standard replaces GB/T 19951-2005.The main differences between this Standard and GB/T 19951-2005 are as follows. - Adjust the terms (see Clause 3; Clause 3 of the 2005 edition); - ADD test conditions, test location, and discharge modes (see Clauses 4, 5, and 7); - There are major modifications to the provisions on test apparatus and instrumentation (output voltage, discharge resistance, and reduction of apparatus variety specified) (see Clause 6; Clause 4 of the 2005 edition); - MAKE major adjustments to the test methods, including component powered-up test method and vehicle test method (see Clauses 8 and 10; Clauses 5 and 6 of the 2005 edition); - Adjust the requirements for evaluation of test results and test report (see Clauses 8, 9, and 11; Clauses 5~7 of the 2005 edition); - ADD “Guidelines for current target design”, “Selection guidance for test method of component discharge”, and “Optional test set-up and procedure for components (powered-up test)”, to specify the calibration, test methods, and test procedure of the device (see Annexes B, D, and E); - CHANGE the function performance status classification to an informative annex (see Annex C; Annex B of the 2005 edition). This Standard uses the redraft law to modify and adopt ISO 10605.2008 “Road vehicles - Test methods for electrical disturbances from electrostatic discharge”. The structural adjustment of this Standard compared with ISO 10605.2008 is as follows. - No subclauses under 6.3; - No subclauses under 9.3.3; - ADD 9.3.7; - Delete C.3 and C.4; - The content of Annex F of the source text is adjusted to Annex E. There are technical differences between this Standard and ISO 10605.2008. The clauses involved in these differences have been marked by a vertical single line (|) at the blank of the outer margin. The technical differences between this Standard and ISO 10605.2008 and their reasons are as follows. - About normative references, this Standard has made adjustments with technical differences, to adapt to the technical conditions of China. The adjustments are reflected in Clause 2 “Normative references”, as follows. Delete ISO 7637-1 and ISO 11452-1; ADD a reference to GB/T 29259-2012. - GB/T 29259-2012 has included the terms of electrostatic discharge, human ESD model, reference plane, and electrostatic discharge simulator (generator), so delete the 3.5, 3.6, 3.7, and 3.10 contents of the source text. - In order to clearly describe the contact discharge current waveform, and to facilitate understanding of the meanings of t1 and t2 in Table 2, with reference to the relevant standard, below Table 2, ADD Figure 3 “Schematic diagram for contact discharge mode waveform parameters”. The subsequent figure numbers change in order. - ADD the functional requirements after component test, as post-test result judgement, see 9.3.7. - The 6.3.2 content of the source text is unnecessary statement, and is easy to cause misunderstanding, so it is deleted. This Standard makes the following editorial changes. - Modify the standard name; - INCORPORATE the amendments of ISO 10605.2008/Amd 1.2014 and ISO 10605.2008/Cor. 1.2010.The clauses involved in these amendments have been marked by a vertical double line (ǁ) at the blank of the outer margin; - For ease of understanding, GIVE a note to the current/test voltage (A/kV) in Table 2; - The description of test voltage in 8.4.5 of the source text is the same as that in 8.3.6.This Standard does not repeat the description but refers to 8.3.6 instead. 9.3.3, 9.3.4, 9.3.5, 9.3.6, 10.3.3 are all treated in this way; - Delete the comment for “1” in Figure B.1c) “Cut side view” in Annex B of the source text and change “1” to “M3 screw hole”; - In order to maintain the unification of expression and understanding of function performance status classification (FPSC) between several standards of electromagnetic immunity series, the content of function performance status classification (FPSC) of Annex C is directly referred to GB/T 33014.1; - The source text’s Annex E “Rationale for air discharge generator verification” is not directly related to the technical requirements and test methods of the standard, and the drafting is extremely non-standard and so deleted. This Standard was proposed by Ministry of Industry and Information Technology of the PRC. This Standard shall be under the jurisdiction of National Technical Committee of Auto Standardization (SAC/TC 114). Responsible drafting organizations of this Standard.

For the dated references, only the editions with the dates indicated are applicable to this document. For the undated references, the latest edition (including all the amendments) are applicable to this document. GB/T 29259-2012 Road vehicle - Electromagnetic compatibility terminology3 Terms and definitionsThe terms and definitions defined in GB/T 29259-2012 and the following apply to this document. 3.1 Device under test; DUT Single component or combination of components as defined to be tested. 3.2 Air discharge Test method characterized by bringing the test generator charging electrode close to the device under test (DUT); the discharge is by arcing on the DUT.4 Test conditionsThe environmental conditions during the test are as follows. When other test conditions are used, they shall be recorded in the test report.5 Test locationIt shall be carried out in a laboratory which meets environmental conditions. Special locations, such as a shielded room or an anechoic chamber, may be used.6 Test apparatus and instrumentationThe ESD generator should be able to generate a repetition rate of at least 10 discharges per second. The electrode for air discharge is shown in Figure 2.For air discharge at test voltages higher than 15 kV, larger electrode tip can be used to avoid pre-discharge.7 Discharge modesDuring the test, discharges can be applied by two discharge modes. contact and air. See Annex D for guidance on air versus contact discharge modes. In contact discharge mode, before applying the discharge, the tip of the ESD generator’s discharge electrode is brought in contact with the DUT.8 Component test methodThe ESD generator shall be configured with the 330 pF or 150 pF capacitor, depending on the DUT location in the vehicle, and the 330 Ω resistor. Before applying any discharges to the DUT, according to Annex A, it shall periodically verify the ESD generator.9 Component test methodThe test shall subject the DUT to simulated direct discharges from humans during the assembly process or in the service case. The test shall be performed by contact discharge on all pins and contacts, and/or air discharge mode on all surfaces and points that can be touched during the assembly process or in the service case.10 Vehicle test methodChoose a generator capacitance of 330 pF for areas that can easily be accessed only from the inside of the vehicle and resistance of 330 Ω or 2 kΩ. Conductive surfaces shall be tested using contact mode discharges. For contact discharge, use the contact discharge tip. Air discharge may also be applied to conductive surfaces, if required in the test plan. Non-conductive surfaces shall be tested using air mode discharges. For air discharge, use the air discharge tip.11 Test reportThe test report shall include detailing information regarding the test equipment, test levels, test area, systems tested, discharge points, environmental conditions, grounding conditions, DUT operating mode, DUT monitoring conditions, system interactions and any other relevant information regarding the test. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
