DIN EN ISO 1716:2010-11

This standard specifies a test method for the determination of the gross heat of combustion (PCS) of products at constant volume in a bomb calorimeter. Annex A contains an appropriate calculation method for the determination of the net heat of combustion (PCI) when required. Information on the precision of the test method is given in Annex B. In the test, a test specimen of specified mass is burned under standardized conditions, at constant volume, in an atmosphere of oxygen, in a bomb calorimeter calibrated by combustion of certified benzoic acid. The gross heat of combustion determined under these conditions is calculated on the basis of the observed temperature rise, taking account of heat loss and the latent heat of vaporization of water. This is a test method for determining an absolute value of the gross heat of combustion of a product and it does not take not into account any adherent variability of the product. The European Standard has been prepared by ISO/TC 92/SC 1 "Fire initiation and growth" (under ISO-lead mode of collaboration as defined in the Vienna Agreement) and CEN/TC 127 "Fire safety in buildings", the secretariats of which are held by BSI (United Kingdom). At DIN the national Mirror Committee is Working Committee NA 005-52-01 AA "Brandverhalten von Baustoffen und Bauteilen - Baustoffe" ("Fire behaviour of building materials and building components - Building materials") of NABau.
