GB/T4208-2008 enclosure protection class (IP code) describes the classification system for the degree of protection provided by the electrical equipment enclosure. Although this system is suitable for most types of electrical equipment, it is not necessary to apply all levels of protection for a particular type of electrical equipment. The manufacturer of the equipment should be advised to determine the applicable degree of protection and the equipment components to which it is applied. Below we will briefly introduce which terms and definitions apply to the GB/T4208-2008 standard.
1. Enclosure: A component of a device that protects the device from certain external influences and prevents direct contact in all directions. Note: This definition is derived from the current International Electrotechnical Vocabulary (IEV) and is interpreted as follows within the scope of this standard:
(1) The outer casing provides protection for the human or animal from accessing dangerous parts inside the casing.
(2) Parts that prevent or restrict the entry of the test piece specified in this standard, or the formation of holes or other openings, whether on the outer casing or in the covering equipment, are considered as part of the outer casing and can be moved without using a key or a tool. Except for the parts except.
Second, direct contact: contact between people or animals and live parts. Note: This IEV definition gives information that “direct contact†in this standard is replaced by “close to hazardous partsâ€.
Third, the degree of protection: according to the standard inspection method, the degree of protection provided by the outer casing to the dangerous parts, to prevent the entry of fixed foreign objects or water.
