这些方法包括定义和规定车辆部件中使用的简单弹性体和简单预制弹性体隔离器动态特性的测试程序。这里简单的定义是在小于或等于25 Hz的频率下测试的固体（非液压）部件。

These methods cover testing procedures for defining and specifying the dynamic characteristics of simple elastomers and simple fabricated elastomeric isolators used in vehicle components. Simple, here, is defined as solid (non-hydraulic) components tested at frequencies less than or equal to 25 Hz.
