Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
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).
