TEST FOR DETERMINATION OF THE GROSS HEAT OF COMBUSTION (CALORIFIC VALUE) WITH METHODS ACCORDING TO PN-EN ISO 1716
Principle of the method.
The measurement consists in the total burn of the sample of material in the atmosphere of oxygen under high - pressure inside the bomb calorimeter immersed in the water. Based on the measurement of the increase of the water temperature in the calorimeter a gross heat of combustion is determined.
From a representative amount of a homogeneous product, or a component of a non-homogeneous product, compose a sample from at least five randomly selected parts taken from across the thickness. A minimum mass of 50g shall be taken from a homogeneous product and a substantial component of a non-homogeneous product. A minimum mass of 10g shall be taken for a non-substantial component of a non-homogeneous product.
Applying research methods:
- civil engineering (requirements according to PN-EN 13501 for European Classification System: A1, A1fl, A1L, A2, A1L, A2fl, and A2L),
- shipbuilding (requirements according to IMO 2010 FTP Code part 5).
