This European Standard specifies the characteristics and performance requirements for masonry units
manufactured from clay for which the main intended uses are protected or unprotected masonry structure (see
definitions 3.3 and 3.4) (e.g. facing and rendered masonry, loadbearing or non-loadbearing masonry
structures, including internal linings and partitions, for building and civil engineering).

This European Standard includes those clay masonry units of an overall non-rectangular parallelepiped
shape.
It defines the performance related to e.g. dimensional tolerances, strength, density measured according to the
corresponding test methods contained in separate European Standards.
It provides for the assessment and verification of constancy of performance (AVCP) of the product to this
European Standard.
The marking requirement for products covered by this European Standard is included.
This European Standard does not specify standard sizes for clay masonry units, nor does it specify standard
work dimensions, angles and radii of specially shaped clay masonry units. This European Standard does
not include method of measurement of angles and radii characteristics of specially shaped clay masonry
units.
This European Standard does not cover requirements for the following: units for paving, flue liners and storey
height clay masonry units and clay masonry units with an incorporated thermal insulation material bonded to
the faces of the unit susceptible to be exposed to fire. It does, however, include clay masonry units for
external chimney masonry.
