This European Standard specifies the equipment and procedures for determining the organic content of thermal insulating materials.The method is aimed at determining the organic content for products which are inorganic, i.e. products containing a low percentage of organic compounds, either unfaced products or the insulating material of a faced product.NOTE 1It can be used to verify that a thermal insulating product complies with the requirements in prEN 13501-1 Fire classification of construction products and building elements - Part 1: Classification using test data from reaction to fire test to be in Euroclass A1 without testing.NOTE 2The standard is not intended for the determination of organic content in the presence of water of hydration and/or combined carbonate, sulphate etc.NOTE 3The standard is not intended for the determination of organic content of adhesives, facings and/or coatings.
