This European Standard specifies the characteristics and performance requirements of calcium silicate masonry units for which the main intended uses are inner walls, outer walls, cellars, foundations and chimneys, including those of an overall non-rectangular parallelepiped shape, specially shaped and accessory units.
This European Standard is intended to apply to all calcium silicate masonry units.
This European Standard does not cover units with more than 60 % volume of voids.
This European Standard does not cover products made from shale as a major raw material.
This European Standard does not cover storey height panels.
This European Standard does not cover units intended for use as a damp proof course.
This European Standard does not specify standard sizes for calcium silicate masonry units, nor standard work dimensions.
This European Standard does not cover units with an incorporated thermal insulating material placed on a face susceptible to be exposed to fire. It defines the performance related to strength, density, dimensional accuracy, geometry and
freeze/thaw resistance, measured according to the corresponding test methods contained in separate European Standards.
It provides for the evaluation of conformity of the product to this European Standard. The marking requirement for products covered by this European Standard is also included.
