35、3:2015-11EN 771-3:2011+A1:2015 (E) 5 1 Scope This European Standard specifies the characteristics and performance requirements of aggregate concrete masonry units made from dense and lightweight aggregates or a combination of both for which the main intended uses are common, facing or exposed masonr
36、y in load bearing or non-load bearing building and civil engineering applications. The units are suitable for all forms of walling, including single leaf, external leaf to chimneys, cavity wall, partitions, retaining, and basement. They can provide fire protection, thermal insulation, sound insulati
37、on and sound absorption. This European Standard includes aggregate concrete masonry units of an overall non-rectangular parallelepiped shape, !specially“ shaped and accessory units. !It defines the performance related to e.g. strength, density, dimensional accuracy, and provides for the assessment a
38、nd 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 aggregate concrete masonry units, nor standard work dimensions
39、and angles of specially shaped aggregate concrete masonry units. It does not cover storey height panels, chimney flue linings nor units intended for use as a damp proof course. It does not cover units with an incorporated thermal insulation material bonded to the faces of the unit susceptible to be
40、exposed to fire. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
