GJB 150A与GJB 150内容对比和分析（一）

GJB 150经过近十年左右的修订，其新版GJB 150A于2009年8月1日开始实施。GJB 150A是完全等效采用美国军用标准MIL-STD-810F《环境工程指南和实验室环境试验》中有关部分编制而成的。作为等效标准，GJB 150A与810F基本相同，因而在编写格式、技术内容和标准的性质等方面与GJB 150（参照MIL-STD-810C）差别较大。GJB 150是我国军工产品研制生产中最为重要、应用最为广泛的试验标准，因而GJB 150A颁布后深受使用方和研制方各类人员的密切关注。文章力图对GJB 150A与GJB 150的区别作一简单介绍。由于篇幅较大，分为两部分:第一部分简单介绍GJB 150实施近25年来，对确保我国军工产品环境适应性、促进环境试验行业发展和装备环境适应性与环境工程技术概念的提出和完善，均发挥了重大作用；简单介绍了GJB 150A与GJB 150两个标准的性质、各试验方法编写格式、标准的总则或通用要求之间的差别；第二部分则是在对GJB 150/150A两个标准中各个试验方法对比分析的基础上，介绍了试验方法增删情况，两个标准均包括的试验方法中试验程序和内容的差别；最后概述了GJB 150A的基本特点。

A comparative study of GJB 150A and GJB 150 (Part I)

GJB 150A,the revised version of GJB 150 after about ten year’s deliberation,was put into effect on August 1st,2009.The new version completely adopts MIL-STD-810F "Environmental Engineering Considerations and Laboratory Tests".As one equivalent standard,GJB 150A is the same as 810F,with some clear differences from its predecessor GJB 150(810C) in terms of compiling format,technical content and standard property.Since GJB 150 has been the most important and widely applied test standard in our country’s military product development and manufacturing,GJB 150A has received much concern from product users and manufacturers since its issuance.This paper analyzes the differences between GJB 150 and GJB 150A in two parts.The first part briefly summarizes the implementation of GJB 150 in 25 years,and the important role it had played,such as guaranteeing the environmental adaptability of domestic military products,promoting the development of environmental test industry,and proposing and improving the concepts of environmental adaptability and environmental engineering techniques.The second part discusses the differences between GJB 150A and GJB 150,including the standard property,compiling format and content of various test methods,and general requirements.
