These classifications also take into account the degree of restrictions on the use of the product, from Strict restrictions (such as in a temperature-controlled room) to unrestricted conditions. GB/T 4798 is intended to consist of 10 parts. --Part 1.Storage. The purpose is to provide a classification of environmental parameters and their severity during storage of the product. --Part 2.Transportation and handling. The purpose is to provide the environmental parameters and their severity that the product is subjected to during transportation and handling. Coolness rating. --Part 3.Fixed use in weather-protected locations. The purpose is to provide the product's ability to withstand fixed use in weather-protected locations. Environmental parameter groups and their severity classification. --Part 4.Stationary use in places without weather protection. The purpose is to give the product's ability to withstand stationary use in places without weather protection. Environmental parameter groups and their severity classification. -- Part 5.Use in ground vehicles. The purpose is to provide environmental parameters to which products installed in vehicles but not constituting the vehicle are subjected Groups and their severity ratings. -- Part 6.Marine. The purpose is to provide the environmental parameter groups and severity classifications to which products installed on ships are subjected. --Part 7.Portable and non-stationary use. The purpose is to provide a set of environmental parameters that products that are used in a portable and non-stationary manner are subject to. and its severity classification. --Part 9.Microclimate inside the product. The purpose is to provide the environmental parameter group and its severity level to which the internal components of the product are subjected. Degree classification. -- Part 10.Introduction. The purpose is to provide guidance for the use of GB/T 4798. --Part 11.Drawing of environmental severity distribution map. The purpose is to provide the drawing of product service environment severity distribution map method. The formulation of this document can provide effective guidance for the research and development, design, manufacturing, and operation and maintenance of products serving in complex environmental conditions, and improve the Environmental durability in different types of environments ensures long-term safe and reliable operation and high-quality development of the product. Classification of environmental conditions Classification of environmental parameter groups and their severity Severity scale Part 11.Environmental severity Distribution Mapping1 ScopeThis document provides the basic environmental data and environmental severity level required for drawing the distribution map of environmental severity of electrical and electronic products. Methods for drawing classification and distribution maps. This document is applicable to the drawing of environmental parameter distribution diagrams and environmental response characteristic distribution diagrams of electrical and electronic products. Environmental parameters include temperature, phase Environmental response characteristics include corrosion, wind speed, condensation, solar radiation, salt spray concentration, hydrogen sulfide concentration, ground lightning density, ice thickness, etc. Aging, corrosion, etc. This document is applicable to electrical and electronic products used in places without climate protection and places with climate protection, such as new energy power generation equipment, Power grid equipment, energy storage equipment, communication equipment and rail transit equipment, etc.2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document.
