标准范围

ISO 11357规定了几种用于聚合物和聚合物共混物热分析的差示扫描量热法(DSC)方法，例如热塑性塑料（聚合物、模制化合物和其他模制材料，有或没有填料、纤维或增强材料）；热固性材料（未固化或固化材料，有或没有填料、纤维或增强材料）；弹性体（有或没有填料、纤维或增强材料）。ISO 11357旨在观察和测量上述材料的各种性质，例如物理转变(玻璃化转变、相转变如熔化和结晶、多晶型转变等)；化学反应（弹性体和热固性材料的聚合、交联和固化等）；氧化稳定性；热容量。ISO 11357-1:20 09规定了差示扫描量热法的许多一般方面，例如原理和设备、取样、校准以及所有以下部分共有的程序和测试报告的一般方面。ISO 11357的后续部分给出了执行特定方法的详细信息。

ISO 11357 specifies several differential scanning calorimetry (DSC) methods for the thermal analysis of polymers and polymer blends, such as

• thermoplastics (polymers, moulding compounds and other moulding materials, with or without fillers, fibres or reinforcements);
• thermosets (uncured or cured materials, with or without fillers, fibres or reinforcements);
• elastomers (with or without fillers, fibres or reinforcements).

ISO 11357 is intended for the observation and measurement of various properties of the above-mentioned materials, such as

• physical transitions (glass transition, phase transitions such as melting and crystallization, polymorphic transitions, etc.);
• chemical reactions (polymerization, crosslinking and curing of elastomers and thermosets, etc.);
• the stability to oxidation;
• the heat capacity.

ISO 11357-1:2009 specifies a number of general aspects of differential scanning calorimetry, such as the principle and the apparatus, sampling, calibration and general aspects of the procedure and test report common to all following parts.Details on performing specific methods are given in subsequent parts of ISO 11357.
