GJB 150A的应用和剪裁

Application and tailoring of GJB 150A

文章阐述了GJB 150A作为新修订标准的应用原则,强调了应用GJB 150A这一剪裁标准最大的困难是如何剪裁,指出了GJB 150A剪裁的主要内容包括试验方法的剪裁、试验程序(试验项目)的剪裁、试验程序(试验项目)实施顺序的剪裁、试验条件的剪裁和试验实施步骤的剪裁,并基于实验室环境试验类型分别详细描述这5种剪裁的依据、考虑因素、剪裁的具体方法、剪裁时机以及剪裁由谁来进行和认可,强调了实验室环境试验剪裁的依据是产品研制总要求和成品协议(合同)中的环境适应性要求,指出了研制生产过程中不同阶段的环境试验应以环境适应性要求指标为基线对其试验项目和试验条件等进行剪裁。

This paper discusses the application principle of the GJB 150A and shows how to tailor it to deal with its restrictions, and the tailoring includes the tailoring of the test methods, the tailoring of the test procedures, the tailoring of the test sequences, the tailoring of the test conditions and the tailoring of the test steps. Four important tailoring factors on the basis of laboratory environmental test types are the tailoring foundation, the tailoring methods, the tailoring time and the persons to do the tailoring and to take the responsibility. Finally, it is pointed out that tailoring is determined by the general development requirements and the environmental worthiness requirements of the products. In different development phases, the test procedures and the test conditions in the environmental test should be tailored by indexes of the environmental worthiness requirement.
