Plastics — Determination of dynamic mechanical properties — Part 1: General principles

active, Most Current
Organization: ISO
Publication Date: 1 April 2019
Status: active
Page Count: 30
ICS Code (Plastics in general): 83.080.01
scope:

The various parts of ISO 6721 specify methods for the determination of the dynamic mechanical properties of rigid plastics within the region of linear viscoelastic behaviour. This document specifies the definitions and describes the general principles including all aspects that are common to the individual test methods described in the subsequent parts.

Different deformation modes can produce results that are not directly comparable. For example, tensile vibration results in a stress which is uniform across the whole thickness of the specimen, whereas flexural measurements are influenced preferentially by the properties of the surface regions of the specimen.

Values derived from flexural-test data will be comparable to those derived from tensile-test data only at strain levels where the stress-strain relationship is linear and for specimens which have a homogeneous structure.
