GB/T 4798.11-2024 "Classification of environmental conditions—Classification of groups of environmental parameters and their severities—Part 11: Drawing of environmental severity distribution maps" is applicable to the drawing of distribution maps for environmental parameters and response characteristics of electrical and electronic products. It specifies the treatment methods for environmental parameters such as temperature, humidity, and salt spray concentration, as well as response characteristics like corrosion and aging. The standard employs a grid method to divide regions and interpolates missing data. By establishing an environment-response correlation model, distribution maps are drawn to provide a basis for environmental service condition analysis in product development, design, and operation and maintenance.
