Abstract

Abstract: Pressurization, depressurization and repressruization test is primarily applied to investigate the adaptability of electronic equipment stand-alone products to the depressurization and repressruization environment under the condition of above normal atmospheric pressure. Combining with the characteristics of pressurization, depressurization and repressruization test, we develop a set of pressurization, depressurization and repressruization test equipment. It solves the difficult problems such as gas temperature decrease during depressurization test, condensation on the inner surface of specimens and containers, precise control of rate during depressurization and repressruization, etc. The results prove that all of the test equipment technical indicators meet the technical requirement, which can ensure the smooth process of pressurization, depressurization and repressruization test.

Key words: electronic equipment stand-alone products, pressurization, depressurization and repressruization, test method, test equipment
