Characteristics and performance specifications of gypsum-based adhesives for assembling gypsum blocks/units.

This European Standard specifies the characteristics and performance of gypsum based adhesives used for assembling gypsum blocks or other gypsum units. It covers the following performance characteristics related to the essential requirements : - reaction to fire ; - release of dangerous substances ; measured according to the corresponding European test methods. It defines the reference tests for technical specifications. It provides for the evaluation of conformity of the product to this European Standard. This European Standard covers also additional technical characteristics that are of importance for the use and acceptance of the product by the Building Industry : - direct airborne sound insulation ; - bond strength ; - thermal resistance calculated with thermal conductivity values from the Table 1 (see 5.3.2).
