Područje primjene nacrta:
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
