This standard specifies the corresponding climatic and environmental conditions at different altitudes in the design, production, installation and use of electrical products. This standard applies to electrical products designed, produced, installed and used at an altitude of 5 km or less. It can also be used as a reference for electrical products in transportation and storage. This standard provides a basis for the formulation of environmental conditions severity levels for relevant product standards.
