CE標準解讀：EN ISO 11357-1《塑料 - 差示掃描量熱法 (DSC) - 第 1 部分：一般原則》

ISO 11357-1:2016 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), and - elastomers (with 

or without fillers, fibres or reinforcements). ISO 11357-1:2016 is intended for the observation and measurement of various properties of, and phenomena associated with, 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, and - the heat capacity. ISO 11357-1:2016 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 (see Foreword).

ISO 11357-1:2016 規定了幾種用于聚合物和聚合物共混物熱分析的差示掃描量熱法 (DSC) 方法，例如 - 熱塑性塑料（聚合物、模塑料和其他模塑料，有或沒有填料、纖維或增強材料）， - 熱固性材料（未固化或固化材料，有或沒有填料、纖維或增強材料），以及 - 彈性體（有或沒有填料、纖維或增強材料）。 ISO 11357-1:2016 旨在觀察和測量上述材料的各種特性以及與之相關的現象，例如 - 物理轉變（玻璃化轉變、熔化和結晶等相變、多晶型轉變等） .), - 化學反應（彈性體和熱固性材料的聚合、交聯和固化等）， - 氧化穩定性，以及 - 熱容量。 ISO 11357-1:2016 規定了差示掃描量熱法的許多一般方面，例如原理和設備、采樣、校準以及以下所有部分共有的程序和測試報告的一般方面。 ISO 11357 的后續部分給出了執行特定方法的詳細信息（參見前言）。
