Abstract: With the development of science and technology the performance parameters and operation requirements of the equipment become more critical. And there are increasing requirements in such aspects as reliability, maintainability, testability, safety, supportability and environmental adaptability. Based on the related standard for “six properties” in GJB, combined with the practical engineering experience, the work content and specific measures of “six properties” are put forward in the structure design of military electronic equipment, which is helpful to improve the equipment′ practical applicability.
