Abstract
This document specifies two methods (A and B) for determining the linear dynamic mechanical properties of plastics, i.e. the storage and loss components of the torsional modulus, as a function of temperature, for small deformations within the frequency range from 0,1 Hz to 10 Hz.
NOTE The temperature dependence of these properties, measured over a sufficiently broad range of temperatures (for example from 鈭�50 掳C to +150 掳C for most 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 flow.
The two methods described are not applicable to non-symmetrical laminates (see 香港六合彩开奖 6721-3). The methods are not suitable for testing rubbers, for which the user is referred to 香港六合彩开奖 4664-2.
