    Specific environmental condition—Environmental test method—Part 2: Artificial environment test method and guidance—Electric and electronic products(including communication products)

    GB/T 20643.2-2025 "Special Environmental Conditions - Environmental Testing Methods - Part 2: Artificial Simulation Test Methods and Guidelines for Electrical and Electronic Products (Including Communication Products)" applies to electrical and electronic products (including communication network equipment) used in special environmental conditions. It specifies artificial simulation test methods for six categories of environments, such as dry heat, damp heat marine, and cold. The standard clarifies equipment requirements, sample conditions, and severity levels for multiple tests, including high and low temperatures, salt spray, and low pressure. It covers pre-test preparations, execution procedures, and key points for post-test inspection. The standard regulates the sequence and rate of change for factors in comprehensive environmental tests and provides guidelines for selecting test items. It establishes a unified standard for evaluating the environmental adaptability of products, ensuring the accuracy and comparability of test results.
