BS EN 12059 is a European Standard that covers natural stone testing methods used for both internal and external surfaces of constructions. The main aim of BS EN 12059 is to offer manufacturers the best industry practices for demonstrating the effectiveness of natural stones for structures, not only for enhancing aesthetics but also for thermal insulation and protection against extreme weather conditions.
BS EN 12059 specifies requirements for the following stone units:
Note 1: BS EN 12059 does not include stone masonry units, as defined in EN 771-6, the stone which is a ‘caston’ finish to pre-cast concrete or agglomerated stones.
Note 2: Moreover, BS EN 12059 does not cover commemorative or funeral stones and sculptures, when they do not show the above-mentioned characteristics.
BS EN 12059 on natural stone products is useful for:
Dimensional stonework is the stone element worked to any specific dimensions for inside or outside application in the building sector. It includes flat stone elements and curved stones or three-dimensional shaped stone elements. The dimension stone industry provides quality products that meet the design and construction requirements of the buildings. The dimensional work of natural stone is an important factor to consider when selecting products and materials for your construction that needs specific sizes or shapes, colour, texture and pattern, and surface finish.
In this regard, BS EN 12059 provides the best industry recommendations on the product’s geometric characteristics and requirements of natural stone for dimensional work.
BS EN 12059 also covers guidance on the marking, packaging, evaluation of conformity and factory production control of the natural stone.
As a result, complying with BS EN 12059 can help demonstrate the performance and durability of natural stones, thus determining whether or not they are fit for purpose in a specific environment.
