Omfang

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.
