ASTM E756-98
Historical Standard: ASTM E756-98 Standard Test Method for Measuring Vibration-Damping Properties of Materials
SUPERSEDED (see Active link, below)
ASTM E756
1. Scope
1.1 This test method measures the vibration-damping properties of materials, including loss factor, [eta], Young's modulus, E, and shear modulus, G. Accurate over a frequency range of 50 to 5 kHz and over the useful temperature range of the material, this test method is useful in testing materials that have application in structural vibration, building acoustics, and the control of audible noise. Such materials include metals, enamels, ceramics, rubbers, plastics, reinforced epoxy matrices, and woods that can be formed to the test specimen configurations.
