This European Standard specifies the characteristics and performance of gypsum blocks with smooth faces
for which the main intended uses are construction of non-load bearing partitions or independent wall linings
and the fire protection of columns, lift shafts, etc. The gypsum blocks are not used to build ceilings.
It 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.
It describes the reference tests for technical specifications.
This European Standard also covers additional technical characteristics that are of importance for the use and
acceptance of the product by the construction industry:
? convenience class for density;
? convenience class for pH;
? surface hardness.
It provides for the evaluation of conformity of the product to this European Standard.
This European Standard does not cover gypsum blocks of thickness less than 50 mm or gypsum storey height
units.
