警告——本文件的使用可能涉及危险材料、操作和设备。本文件并不旨在解决与其使用相关的所有安全问题。用户有责任在使用前建立适当的健康和安全实践，并确定任何其他限制的适用性。本文件规定了根据加热条件下线性温度扫描期间测量的动态机械性能确定玻璃化转变温度（Tg）值的方法。 玻璃化转变温度是非晶态聚合物或部分晶态聚合物的非晶态区域从坚硬且相对易碎的玻璃态转变为橡胶状或粘性液体状态的指标。交叉引用:ISO 472ISO 6721-1ISO 11357-2购买时可用的所有现行修订版均包含在本文件的购买中。

WARNING — The use of this document may involve hazardous materials, operations and equipment. The document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user to establish appropriate health and safety practices and to determine the applicability of any other restrictions prior to its use.This document specifies methods for determining a value of the glass transition temperature (Tg) from the dynamic mechanical properties measured during a linear temperature scan under heating conditions. The glass transition temperature is an indicator of the transition from a hard and relatively brittle glassy state to a rubbery or viscous liquid state in an amorphous polymer or in amorphous regions of a partially crystalline polymer.Cross References:ISO 472ISO 6721-1ISO 11357-2All current amendments available at time of purchase are included with the purchase of this document.
