Scope
This standard is applicable to the protection classification of electrical equipment shells with a rated voltage not exceeding 72.5kV against external mechanical collisions This standard is only applicable to enclosures with specific requirements for the classification of external mechanical collision protection The purpose of this standard is to specify:
a) the definition of the degree of protection provided by the enclosure of electrical equipment to protect internal equipment from harmful effects caused by mechanical collisions B) Identification of protection level C) Requirements for each type of marking D) The tests that should be conducted to confirm whether the shell meets the requirements of this standard Each technical committee still has the right to decide on the extent and manner of adopting this classification method in their standards, and to define the "shell" of the equipment under their jurisdiction. However, for any designated grading, the test shall not differ from the provisions of this standard. If necessary, supplementary requirements can be added to the corresponding product standards For certain specific types of equipment, the product technical committee may specify different requirements while ensuring the same level of safety protection This standard only specifies enclosures that meet the requirements of the corresponding product standard in any other way for their intended use, and from the perspective of materials and processes, under normal usage conditions, the enclosure should ensure the indicated level of protection This standard also applies to empty enclosures, as long as the surface of the enclosure meets the requirements of routine testing and the selected protection level is suitable for this type of equipment
