DESCRIPTION

BS EN ISO 6721-3:2021 - TC


This standard BS EN ISO 6721-3:2021 - TC Tracked Changes. Plastics. Determination of dynamic mechanical properties is classified in these ICS categories:
  • 83.080.01 Plastics in general

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