scope:

This European Standard deals with the requirements and the basic performance criteria for blocks made in lightweight materials used as formwork during the construction of the floor system. The blocks are used in conjunction with precast concrete beams in compliance with EN 15037-1, with or without cast-in-situ concrete for the construction of beam-and-block floor systems. This standard doesn't deals with blocks made in polystyrene, with or without tong, or combined with different materials where polystyrene contribute to more than 50 % of the mechanical resistance of the block. These blocks are covered by EN 15037-4, Beam-and-block floor systems - Part 4: Polystyrene blocks. Examples of typology of floor systems are given in Annex B of EN 15037-1.
