DIN Standards Committee Heating and Cooking Equipment

Overview

This European Standard specifies the characteristics and performance of gypsum blocks with smooth faces for which are mainly used for construction of non-load bearing partitions, independent wall linings and the fire protection of columns, lift shafts, shafts for services, etcetera. Gypsum blocks are not used to build ceilings. This standard covers the following performance characteristics related to the essential requirements: - reaction to fire; - resistance to fire; - direct airborne sound insulation; - release of dangerous substances to be measured according to the corresponding European test methods, as well as - thermal resistance to be calculated from the thermal conductivity values given in 4.3.2 of the standard. Reference tests for technical specifications are defined in this standard. This standard also covers additional technical characteristics that are of importance for the use and acceptance of the product by the construction industry: - convenience classes for density; - convenience classes for pH-value. It provides for the evaluation of conformity of products. This European Standard does not cover gypsum blocks of thickness less than 50 mm or gypsum storey height units. The responsible German committee is Working Committee NA 005-09-10 AA "Gips und Gipsprodukte (Sp CEN/TC 241)" ("Gypsum and gypsum based products (Mirror Committee of CEN/TC 241")) at the German Civil Engineering Standards Committee (NABau) at DIN, the German Institute for Standardization.
