Plastics - Determination of dynamic mechanical properties - Part 2: Torsion-pendulum method

DS/EN ISO 6721-2-2008 发布历史

This part of ISO 6721 specifies two methods (A and B) for determining the linear dynamic mechanicalproperties of plastics, i.e. the storage and loss components of the torsional modulus, as a function oftemperature, for small deformations within the frequency range from 0,1 Hz to 10 Hz.The temperature dependence of these properties, measured over a sufficiently broad range of temperatures (for example from -50 °C to +150 °C for the majority of commercially available plastics), gives information on the transition regions (for example the glass transition and the melting transition) of the polymer. It also provides information concerning the onset of plastic f
