This standard describes the rating system provided by the electrical equipment enclosure. Although this system is suitable for most types of electrical
Equipment, but not all types of protection are necessarily applied to specific types of electrical equipment. Manufacturers of equipment should be advised to determine the appropriate protection
Protect grades and apply equipment components of this grade.
The application of this grading system will make the narrative method and the corresponding level of test methods provided by the outer shell as uniform as possible. This
The wider range of products that will make the test equipment suitable will also reduce the number of test equipment required.
The second edition of IEC 60529 takes into account the experience of the first edition and clarifies the requirements. When actually preventing people from approaching dangerous parts
Above the level indicated by the first feature number, this standard provides optional extended ranges by appending the letters A, B, C, and D.
This revision only increases the protection level of the second characteristic number 9 and does not modify the degree of protection already specified in GB/T 4208-2008.
Therefore, the existing test methods are not modified.
In general, the shell labeled with an IP code in the previous version will fit the same level as this version.

The identification of the first characteristic digit indicates that both conditions 5.1 and 5.2 can be satisfied.
The first characteristic number means.
The enclosure protects the person by preventing a part of the human body or the human hand object from approaching the dangerous part;
The enclosure protects the device by preventing solid foreign objects from entering the device.
When the enclosure also meets all levels below a certain degree of protection, this level should be identified only by that number.
If the test is clearly applicable to any lower degree of protection, tests below this level do not have to be carried out.
5.1 Protection from Nearly Hazardous Parts
Table 1 gives a short description and the meaning of the degree of protection to near-dangerous parts.
In the table, only the first characteristic number specifies the degree of protection, and the brief description and meaning are not regarded as the protection level.
According to the provisions of the first characteristic figure, sufficient clearance should be maintained between the test tool and the dangerous part.

At any level below this level, tests below this level do not have to be carried out.
See Chapter 15 for tests.
See Appendix A for examples of IP codes.
8 additional letters
In the relevant product standards, supplemental letters can be used to indicate supplementary content. Supplementary letter placed in the second characteristic number or additional letter
after that.
The content of the supplement should be consistent with the requirements of this standard, and the product standards should clearly state the supplementary requirements for performing this level of testing.
The letter and meaning of the supplementary content are as follows.
The meaning of the letter
H High-voltage equipment
M Waterproof test is carried out when the movable part of the device (such as the rotor of a rotating motor) moves
S Waterproof test is performed when the movable part of the device (such as the rotor of a rotating electric machine) is stationary
W Provide additional protection or treatment to suit the specified climatic conditions
Note. GB 4208-1984 stipulates that W is placed in the same meaning between the IP and the feature number as the W specified in this version is placed after the feature number or additional letter.
Other letters can be used in product standards. In order to avoid the repeated use of supplementary letters, the product standard refers to the requirements of the new letter
B.8.
Without the letters S and M, it means that the degree of protection has nothing to do with the operation of the equipment components. It needs to be tested both when the equipment is running and when it is stationary.
However, if the test can obviously pass under another condition, it is usually sufficient to make a conditional test.
