Abstract:

This article analyzed the content of the US military standard for Cover material， Vehicle， Coated Tactical and Combat， Heavy?duty， Waterproof （MIL?PRF?32002D） and introduced the requirements for the basic properties， mechanical properties， physical and chemical properties， environmental adaptability and other main technical indexes of the envelop materials and corresponding test methods. Moreover， the paper also compared the PLA military standard for General Specification for Packing Envelope （GJB 2682?1996） with the US military standard， and analyzed the similarities and differences between them. The results indicated that MIL?PRF?32002D has more technical index items （22 items） with higher technical index requirements in general. A revision was suggested for the technical indicators of the PLA military standard （GJB 2682） by referring to the US military standards.
