Plastics — Determination of dynamic mechanical properties — Part 3: Flexural vibration — Resonance-curve method

Standard Details

This document specifies a bending-vibration method based upon resonance curves for determining the flexural complex modulus E*f of homogeneous plastics and the damping properties of laminated plastics intended for acoustic insulation, for example systems consisting of a metal sheet coated with a damping plastic layer, or sandwich systems consisting of two sheet-metal layers with an intermediate plastic layer. For many purposes, it is useful to determine these properties as a function of temperature and frequency.
