DIN EN 771-2:2015-11 EN 771-2:2011+A1:2015 (E) 5 1 Scope This European Standard specifies t

34、he 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. This European Standard is intended to apply to all calcium silicate masonry units, including those of an

35、 overall nonrectangular parallelepiped shape, specially shaped and accessory units. It defines the performance related to e.g. strength, density and dimensional accuracy, measured according to the corresponding test methods contained in separate European Standards. It provides for the !assessment an

36、d verification of constancy of performance (AVCP)“ of the product to this European Standard. The marking requirement for products covered by this document is also included. This European Standard does not specify standard sizes for calcium silicate masonry units, nor standard work dimensions and ang

37、les 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 cover units intended for use as a damp proof course, nor units with an incorporated ther

38、mal insulation material bonded to the faces of the unit susceptible to be exposed to fire, nor chimney flue units. 2 Normative references The following referenced documents are indispensable for the application of this document.
