DIN EN 771-6:2011-07

This European Standard specifies the characteristics and performance requirements of masonry units manufactured from natural stone the width of which is equal to or greater than 80 mm and are mainly intended for use as common, facing or exposed masonry units in loadbearing or non-loadbearing building and civil engineering applications. These masonry units are suitable for all forms of coursed or random masonry walling, including single leaf, cavity, partition, retaining and the external masonry to chimneys. They can provide fire protection, thermal insulation, sound insulation and sound absorption. This European Standard also applies to natural stone masonry units of an overall non-rectangular parallelepiped shape, specially shaped and accessory units for internal and external application. It defines requirements for, for instance, strength, petrographic description, density, porosity, dimensional accuracy, thermal conductivity, water absorption, and frost resistance and specifies the evaluation of conformity of the product to this European Standard. The marking requirements for products covered by this European Standard are also included. This European Standard does not apply to storey height panels, natural stone for paving, chimney flue linings or natural stone units intended for use as damp proof course. The Committee responsible for this standard is NA 005-06-02 AA "Koordinierungsausschuss Mauersteine (SpA zu CEN/TC 125/WG 1)" ("Coordinating committee Masonry Units (Mirror Committee of CEN/TC 125/WG 1)") at DIN.
