What is BS EN 771-6 - Natural stone 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 771-6 is the sixth part of the BS EN 771 series of documents that specifies the characteristics and performance requirements of masonry units manufactured from natural stone the width of which is equal to or greater than 80 mm, for which the main intended uses are common, facing or exposed masonry units in the loadbearing or non-loadbearing building and civil engineering applications These units are suitable for all forms of coursed or random masonry walling, including single leaf, cavity, partition, retaining and the external masonry to chimneys. They can provide fire protection, thermal insulation, sound insulation and sound absorption.
BS EN 771-6 includes natural stone masonry units of an overall non-rectangular parallelepiped shape, specially shaped and accessory units for internal and external application.
BS EN 771-6 defines the performance related to e.g., strength, petrographic description, density, porosity, dimensional accuracy, thermal conductivity, water absorption, and frost resistance.
Note: BS EN 771-6 does not cover storey height panels, natural stone for paving, chimney flue linings nor units intended for use as the damp proof course.
Who is BS EN 771-6 - Natural stone masonry units for?
BS EN 771-6 on masonry is useful for:
- Builders and architects
- Interior designers
- Manufacturers of masonry products
- Natural stone specialists
Why should you use BS EN 771-6 - Natural stone masonry units?
Natural stone is a natural product obtained by mining or by quarrying and made into masonry units by a manufacturing process.
The requirements for natural stone masonry units are specified in BS EN 771-6 in terms of the test methods and other procedures.
BS EN 771-6 outlines the physical and mechanical properties of natural stone masonry units.
Description, designation, designation code and classification of natural stone masonry units are all determined in BS EN 771-6.
The marking of units, the packaging, delivery notes or any certificate supplied with the natural stone masonry units is set out in BS EN 771-6.
BS EN 771-6 provides the assessment and verification of constancy of performance (AVCP) with the compliance for natural stone masonry units with the requirements and performance determination of product with the type testing and factory production control.
Moreover, BS EN 771-6 assist you in the production of natural stone masonry ensuring durability, strength and ability to weather stone that lasts for a long time 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.
