EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 771-3 testing. This European standard specifies the characteristics and performance requirements of aggregate concrete masonry units made of dense and lightweight aggregates or a combination of both.
The units are suitable for all types of walls, including single wing, outer wing to chimney, hollow wall, partitions, retaining and basement. They can provide fire protection, thermal insulation, sound insulation and sound absorption. This European standard covers non-rectangular parallelepiped aggregate concrete masonry units, "special" shaped and accessory units in general.
It defines performance regarding strength, density, dimensional accuracy and enables the evaluation and verification of the product's constancy of performance (AVCP) according to this European Standard. The marking requirement for products covered by this European standard is included.
This European Standard does not specify standard dimensions for aggregate concrete masonry units or standard working dimensions and angles for specially shaped aggregate masonry units. It does not include floor-height panels, chimney flue linings, or units intended to be used as a means of protection from moisture. It does not cover units that contain a thermal insulation material adhered to the fire sensitive surfaces of the unit.
The properties of the materials to be used will be included in the production control documentation. If appropriate European Standards exist, they will be used except where aggregates are not required to comply with rating requirements. If not available, the manufacturer must specify the materials and have data on their suitability.
Where necessary, the surface of the coating units may have a compatibility established based on comparison with any approved sample. Comparison should be made at a distance of 3 m under normal daylight conditions. This conformity must be ensured before the units are used.
