Scope

This document specifies a bending-vibration method based upon resonance curves for determining the
flexural complex modulus Ef
* 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.
