标准摘要
[中文适用范围]： 本文件规定了两种方法（A 和 B），用于确定塑料的线性动态机械性能，即扭转模量的存储和损耗分量，作为温度的函数，对于频率范围从 0.1 Hz 到 0.1 Hz 的小变形。 10赫兹。 注：这些特性的温度依赖性是在足够宽的温度范围内测量的（例如，大多数市售塑料从−50°C 到+150°C），提供了有关转变区域的信息（例如玻璃化转变和玻璃化转变）。 聚合物的熔融转变。 它还提供有关塑性流动开始的信息。 上述两种方法不适用于非对称层压板（参见 ISO 6721-3）。 该方法不适用于测试橡胶，用户可参考 ISO 4664-2。 [外文原描述]： 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 −50 °C to +150 °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 ISO 6721-3). The methods are not suitable for testing rubbers, for which the user is referred to ISO 4664-2.
