Research output: Book/ReportReport


The feasibility of oxygen consumption calorimetry to testing of non-combustibility of building materials is studied. The reasons for the ambiguities of the traditional test method are qualitatively discussed. The construction of the gas collecting system added to the conventional test apparatus is described and the necessary formulae for calculating the oxygen consumption are derived. The results of a test series on 11 different materials are given. The oxygen consumption and the simultaneously measured conventional test variables are compared. The results clearly suggest that oxygen consumption calorimetry is a consistent and powerful method for determining the non-combustibility of building materials.
