This European Standard specifies the characteristics and performance requirements of manufactured stone
masonry units for which the main intended uses are facing or exposed masonry in load bearing or non-load
bearing building and civil engineering applications. The 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 standard covers concrete masonry units manufactured to resemble natural stone using casting or
pressing techniques with or without textured surfaces produced, by casting, splitting, washing, blasting or
tooling and with or without variable outline effects. It covers homogeneous masonry units and those consisting
of different facing and backing concrete mixes, but excludes those manufactured with an adhesive bonded
decorative face. This standard does not cover masonry units intended to conform to EN 771-3.
It defines the performance related to e.g. strength, density, dimensional accuracy, surface appearance and
provides for the assessment and verification of constancy of performance (AVCP) 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, masonry units used for chimney flues or units
manufactured with an adhesive bonded decorative face. It does not include products intended to be used as a
damp proof course nor does it specify standard sizes for manufactured stone masonry units or work
dimensions and angles of specially shaped units. It does not cover units with an incorporated thermal
insulation material bonded to the faces of the unit susceptible to be exposed to fire.
