通告描述：

This Draft Rwanda 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 external chimney masonry.
It defines the performance related to strength, density and dimensional accuracy, measured according to the corresponding test methods contained in separate Standards.
It provides for the assessment and verification of constancy of performance (AVCP) of the product to this Standard. The marking requirement for products covered by this document is also included.
This Standard applies to all calcium silicate masonry units, including those of an overall nonrectangular parallelepiped shape, specially shaped and accessory units.
This Standard does not specify standard sizes for calcium silicate masonry units, nor standard work dimensions and angles of specially shaped and accessory units. It does not cover units with more than 60 % volume of voids, nor products made from shale as a major raw material. It does not cover storey height panels.
It does not apply to units intended for use as a damp-proof course, nor units with an incorporated thermal insulation material bonded to the faces of the unit susceptible to be exposed to fire, nor chimney flue units.
