What is BS EN 771-2 - Calcium silicate masonry units about?
BS EN 771 is a series of the European standard on masonry units that is the preformed component intended for use in masonry construction.
BS EN 771-2 is the second part of the BS EN 771 series of documents that 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.
BS EN 771-2 is intended to apply to all calcium silicate masonry units, including those of an overall Non-rectangular parallelepiped shape, specially shaped and accessory units.
BS EN 771-2 defines the performance related to e.g., strength, density and dimensional accuracy, measured according to the corresponding test methods contained in separate European Standards.
Note 1: BS EN 771-2 does not specify standard sizes for calcium silicate masonry units, nor standard work dimensions and angles of specially shaped and accessory units.
Note 2: BS EN 771-2 does not cover units with more than 60 % volume of voids, nor products made from shale as a major raw material and storey height panels.
Note 3: BS EN 771-2 does not cover 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.
Who is BS EN 771-2 - Calcium silicate masonry units for?
BS EN 771-2 on masonry is useful for:
- Builders and architects
- Interior designers
- Manufacturers of masonry products
- Manufacturers and suppliers of calcium silicate
Why should you use BS EN 771-2 - Calcium silicate masonry units?
Calcium silicate masonry is used for several purposes in construction industries such as ornamental works in buildings, masonry works, etc.
The requirements for calcium silicate masonry units are specified in BS EN 771-2 in terms of the test methods and other procedures.
BS EN 771-2 outlines the physical and mechanical properties of calcium silicate masonry units.
Description, designation, designation code and classification of calcium silicate masonry units are all determined in BS EN 771-2.
The marking of units, the packaging, delivery notes or any certificate supplied with the calcium silicate masonry units is set out in BS EN 771-2.
BS EN 771-2 provides the assessment and verification of constancy of performance (AVCP) with the compliance for calcium silicate masonry units with the requirements and performance determination of product with the type testing and factory production control.
Moreover, BS EN 771-2 guides you through the fabrication of calcium silicate masonry units for construction purposes, assuring durability, flexibility, compressive strength, energy efficiency, and low maintenance while giving your buildings an elegant appearance.
Masonry can be used for building structures because of its colour, scale, texture, pattern, and look of permanence, which controls sound, resists fire, and insulates against daily temperature variations.
