ISO 19628:2017描述了两种测定连续增强陶瓷基复合材料(1D、2D、3D)比热容的方法。单向(1D)、双向(2D)和三向(XD),带2<;x≤ 3).这两种方法是:-方法A:滴量热法;-方法B:差示扫描量热法。其适用范围从环境温度到最高温度,具体取决于方法:方法a最多可使用2 250 K,而方法B最多可使用1 900 K。注:方法A仅限于确定给定温度范围内比热容的平均值,并可给出更大范围的结果。

ISO 19628:2017 describes two methods for the determination of the specific heat capacity of ceramic matrix composites with continuous reinforcements (1D, 2D, 3D).Unidirectional (1D), bi-directional (2D) and tridirectional (XD, with 2 < x ≤ 3).The two methods are:- method A: drop calorimetry;- method B: differential scanning calorimetry.They are applicable from ambient temperature up to a maximum temperature, depending on the method: method A can be used up to 2 250 K, while method B is limited to 1 900 K.NOTE Method A is limited to the determination of an average value of the specific heat capacity over a given temperature range and can give a larger spread of results.
