文章分两部分就GJB 150.3A《军用装备实验室环境试验方法 第3部分:高温试验》中的高温日循环贮存和日循环工作,高温恒温贮存和恒温工作试验的环境、适用对象及其特点进行详细分析。第一部分着重介绍GJB 150.3A的各试验程序及其与GJB 150.3和MIL-STD-810C中各试验程序的关系;第二部分对GJB 150.3A提供的自然和诱发的温度日循环数据作为贮存或工作试验条件可应用于哪类设备作了说明,并对目前GJB 150.3A在型号工程应用中存在的一些疑问、误解和问题进行分析和说明,提出了指导性建议。此为第二部分。

Analysis of high temperature test procedures in GJB 150.3A: (Part II) Selection of high temperature diurnal cycle data and application of GJB 150.3A

Since the GJB 150.3A “Military Materiel Laboratory Environmental Test Methods: (Part 3) High Temperature Test” was enacted in 2009, in the applications of its high temperature diurnal cycle storage and operation, the constant temperature storage and operation test procedures, many questions remain to be cleared. This paper (in two parts) makes a detailed analysis of the simulated environment of these procedures, the applicable range and the characteristics. The first part is focused on the test procedures and their relationships with GJB 150.3 and MIL-STD-810C. The second part discusses the applicable range of storage and operation test procedure conditions based on the natural and induced temperature diurnal cycle data in GJB 150.3A. Some other questions, misunderstandings and problems in the engineering applications are also discussed in the second part with some guidance and advice. The following text is the second part.
