GB/T 30038-2013Road vehicles -- Degrees of electrical equipment protection (IP-Code) (English PDF)

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).

Road vehicles - Degrees of

electrical equipment protection (IP-Code)

1 Scope

This Standard specifies degrees of protection (IP-Code) provided by

enclosures of the electrical equipment of road vehicles, and requirements and

tests for each degree of protection.

2 Normative references

The following referenced documents are indispensable for the application of

this document. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any

amendments) applies.

GB/T 2423.37 Environmental testing for electric and electronic products -

Part 2.Test methods - Test L. Dust and sand (GB/T 2423.37-2006, IEC

60068-2-68.1994, IDT)

3 Terms and definitions

For the purposes of this document, the following terms and definitions apply.

Protection provided by an enclosure against access, foreign objects and water

and verified by standardized test methods.

4 Structure and significance of IP-code

Where no characteristic numeral is required, the letter "X" shall be substituted

(or "XX", if none of the two code elements have been indicated). Additional,

supplementary letters may be omitted without substitute.

The following examples explain the use and arrangements of letters in the IP-

Code.

5 Degrees of protection against foreign objects and against access

Tables 2 and 3 give brief descriptions of the degrees of protection against

foreign objects and against access with the relevant requirements.

6 Degrees of protection against water

Table 4 gives brief descriptions of the degrees of protection against water with

the relevant requirements.

7 Designation examples

The designation IP2X is the degree of protection for the complete enclosure,

and IP5KX is the degree of protection for the cover of a part inside the complete

enclosure.

8 Requirements and testing

Probes for determining the degrees of protection against foreign objects and

access are shown in Table 5.When carrying out the tests with the ball, it shall

avoid the influence of probe handle and guard on the tests.

9 Notes on the assignment of degrees of protection

The decisive criterion of degrees of protection is the type of design of the

enclosure and the impact of foreign bodies to be expected during operation of

the relevant vehicle at the mounting or attachment position.
