Method for Specifying the Characteristics of Auxiliary Analog Equipment for Shock and Vibration Measurements
This Standard defines a method for measuring the dynamic mechanical properties of viscoelastic materials using longitudinal resonance in a bar-shaped test sample. The dynamic mechanical properties are expressed in terms of the frequency dependence of Young’s modulus and loss factor at a given reference temperature. The Standard provides information for constructing such equipment and analyzing the results obtained.
