ASTM E756-05- Standard Test Method for Measuring Vibration-Damping Properties of Materials
Standard test method for measuring the vibration damping properties of materials (e.g. loss factor) as a basis for designing measures to reduce vibration and structure-borne noise.
ASTM E3397-23- Standard Practice for Resonance Testing Using the Impulse Excitation Method
Describes a method for non-destructive resonance testing using impulse excitation (IEM), in which the resonance behavior of components is recorded and compared with reference data in order to detect defects and material deviations.
