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

<p>This document specifies a bending-vibration method based upon resonance curves for determining the flexural complex modulus <em>E<sup>*</sup></em><span><sub>f</sub></span><span><sub> </sub></span>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.</p>
