MIL-STD-202H建立了测试电子和电气部件的统一方法，包括基本环境测试，以确定对军事行动周围自然元素和条件的有害影响的耐受性，以及物理和电气测试。在本标准中，术语“零部件”包括电容器、电阻器、开关、继电器、变压器、电感器等。本标准仅适用于重量不超过300磅或均方根试验电压不超过50000伏的小型零部件，除非另有特别规定。

MIL-STD-202H establishes uniform methods for testing electronic and electrical component parts, including basic environmental tests to determine resistance to deleterious effects of natural elements and conditions surrounding military operations, and physical and electrical tests. For the purpose of this standard, the term "component parts" includes such items as capacitors, resistors, switches, relays, transformers, inductors, and others. This standard is intended to apply only to small component parts, weighing up to 300 pounds or having a root mean square test voltage up to 50,000 volts unless otherwise specifically invoked.
