标准摘要
[中文适用范围]： 本 SAE 标准规定了通过精确的超声波速度测量来测试和测量摩擦材料弹性常数的方法。还描述了测量作为预载荷函数的面外模量以及测量作为温度函数的工程常数的测量方法。最后，制定方法来产生作为预载和温度函数的所有工程常数。 [外文原描述]： This SAE Standard specifies a method for testing and measuring elastic constants in friction materials by precise ultrasonic velocity measurements. Measurement methods are also described for measurement of the out-of-plane modulus as a function of pre-load as well as the measurement of engineering constants as a function of temperature. Finally, methods are formulated to produce all engineering constants as a function of pre-load and temperature.Cross Reference:
