标准摘要
[中文适用范围]： IEC 60068 的这一部分提供了适用于由玻璃或烧结材料制成的表面安装器件 (SMD) 的测试方法，例如包含铁氧体的电容器、电阻器和电感器。存在两种测试方法：本体强度和冲击震动。两项测试的目的都是评估安装期间和之后施加到 SMD 上的机械应力；这些测试着眼于不同的机械应力。相关部件规范应规定适用的测试方法。 [外文原描述]： Provides test methods applicable to surface mounting devices made of glass or sintered materials such as capacitors, resistors and inductors incorporating ferrites. Two test methods exist: body strength and impact shock. The object of both tests is to evaluate the mechanical stresses applied to SMDs during and after mounting; these tests look at different mechanical stresses.
