Foreword
This Standard was drafted in accordance with the rules given GB/T 1.1-2009.
This Standard uses the redrafting method to modify and use ISO 20653.2006
“Road vehicle - Degree of protection (IP-Code) - Protection of electrical
equipment against foreign objects, water and access”.
Technical differences between this Standard and ISO 20653.2006 and the
reasons are as follows.
- IEC 60529 (identical to GB 4208), which is referenced in ISO 20653.2006,
is deleted in this Standard, because it is not used in the text, but only
indicates the source of the definition in the term.
- The header of Table 2, Table 3, Table 4 is adjusted;
- In 8.4.1 of ISO 20653.2006, Figures 3-7 is the error of the original text,
which is modified to Figures 3-6 in this Standard [Translator note. this
standard still uses Figures 3-7 in 8.4.1].
- In 9.3 of ISO 20653.2006, Figure 7 is the error of the original text, which is
modified to Figure 7 and Figure 8 in this Standard; the three items in the
original text and the note of Figure 7 are repeated and not exactly the same,
so the three items are deleted in this Standard to facilitate understanding.
- In the “9K” column of Table 7 of ISO 20653.2006, Figure 8 is the error of
the original text, which is modified to Figure 9 in this Standard [Translator
note. this standard still uses Figure 8].
- There are several errors in Table 5 and Table 6 of ISO 20653.2006, which
are corrected in this standard basing on the context and the understanding
of the standard.
- In the “4K” column of Table 7 of ISO 20653.2006, 0.4 mm is the error of the
original text, which is modified to 0.8 mm in this Standard [Translator note.
this standard still uses 0.4mm], to be consistent with Figure 4.
- It does not give a note for “a” in Figure 4 of ISO 20653.2006, so a note “a -
maximum 200” is added in this Standard with reference to GB 4208.
The editorial modifications are as follows. This Standard is used in conjunction
with GB/T 28046 series of standards, so the “electrical equipment” in the
original heading and scope is modified to “electrical and electronic equipment”,
to correspond to the text.
This Standard is proposed by Ministry of Industry and Information Technology
of the People's Republic of China.
This Standard shall be under the jurisdiction of N National Technical Committee
of Auto Standardization (SAC/TC 114).
Drafting organizations of this Standard. China Automotive Technology
Research Center, Shanghai Institute of Quality Inspection and Technical
Research, Shaanxi Heavy Duty Automobile Co., Ltd., Shenzhen Hangsheng
Electronics Co., Ltd., Dongfeng Trucks Technology Center, Changsha
Automobile Electric Institute, Jinan Power Co., Ltd. of China National Heavy-
