- Scope
- This standard applies to the protection classification of electrical equipment with a rated voltage not exceeding 72.5 kV and protected by enclosures. The purpose of this standard is as follows: a) Specify the enclosure protection level for the following contents of electrical equipment: 1) Prevent the human body from approaching the dangerous parts in the enclosure; 2) Prevent solid foreign objects from entering the enclosure; 3) Prevent damage to the equipment due to water entering the enclosure. harmful effects. b) Identification of the degree of protection. c) Requirements for each protection level. d) Carry out verification tests on the enclosure according to the requirements of this standard. The degree and method of quoting the enclosure protection level for various products, as well as the type of enclosure to be used, are left to the product standards. The tests adopted for the specific protection level shall comply with the provisions of this standard. If necessary, supplementary Require. See Appendix B for detailed rules that can be specified in relevant product standards. For special types of equipment, product standards may specify different requirements, but at least the same level of safety must be guaranteed. This standard only considers the enclosures that meet the requirements of the relevant product standards in all aspects. Under normal use conditions, the materials and workmanship of the enclosure should ensure that the required protection level is achieved. If a certain type of equipment meets the general requirements of the test and the selected degree of protection is suitable for this type of equipment, this standard also applies to empty enclosures of this type of equipment. Damage to the enclosure and the equipment inside the enclosure by external influences such as mechanical damage, rust, aggressive solvents (e.g. cutting fluids), mold, insect damage, solar radiation, icing, humidity (e.g. caused by condensation), explosive gases, or environmental conditions Protective measures and protection against contact with hazardous moving parts outside the enclosure (eg fans) are specified by the relevant product standard.
