GB/T 20643 This part specifies various environmental tests under special environmental conditions - natural atmospheric exposure tests, artificial simulation tests, and the processing of test data, etc. This part is applicable to various environmental test methods under special environmental conditions. "Environmental tests under special environmental conditions" refer to exposing samples to natural or artificially simulated environmental conditions with special climatic characteristics of plateaus, arid deserts, and other regions, in order to evaluate their performance under the storage, transportation, and use conditions that they may encounter in actual use. If required by relevant standards, these test methods can also be used for type testing, batch sampling testing, quality inspection testing, and other types of testing.
