GJB 150.1-1986 "Methods for environmental testing of military equipment, General Provisions" stipulates the general principles and methods for environmental testing of military equipment, including the scope of application, general requirements and test sequence. This standard is used as the basis for a series of test methods and applies to all stages of development, production and delivery of military equipment. Now replaced by GJB 150.1a-2009, it is recommended to use the latest version to ensure that the test methods comply with the latest standards.
