introduction

GB/T 20643 "Environmental test methods for special environmental conditions" covers the test methods of products in my country's dry heat, dry hot desert, plateau, damp heat, damp heat Artificial simulation test methods and guidelines for special climates such as ocean and cold. Currently, GB/T 20643 consists of three parts. --- Part 1.General. The purpose is to propose general rules for natural atmosphere exposure tests and artificial simulation tests under special environmental conditions. and gives general guidelines for environmental testing. --- Part 2.Artificial simulation test methods and guidelines for electrical and electronic products (including communication products). The purpose is to propose Artificial simulation test methods and guidelines for products (including communication products) under special environmental conditions. --- Part 3.Artificial simulation test methods and guidelines for polymer materials. The purpose is to propose the test methods and guidelines for polymer materials under special environmental conditions. Artificial simulation test methods and guidelines. "Special environmental conditions test" is to expose the sample to natural or artificial simulated dry heat, dry hot desert, plateau, damp heat, wet The special climate conditions of hot ocean, cold and other regions, thus affecting the storage, transportation and use of the products in actual use. If required by the relevant standards, these test methods can also be used for type testing, batch sampling testing, quality control, etc. Quantity inspection test and other types of tests. Environmental test methods for special environmental conditions Part 2.Artificial simulation test methods and guidelines Electrical and electronic products (including communication products)
