Status: active
Page Count: 17
ICS Code (Plastics in general): 83.080.01
scope:

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.
