BS EN 12326 is a European standard on slate and stone used for discontinuous roofing and external cladding. The main aim of the BS EN 12326 series is to ensure that the products and materials used for roofing and external cladding offer adequate performance and durability.
BS EN 12326-1 is the first part of the series that specifies requirements for slate and carbonate slate for discontinuous roofing and external cladding, used for assembly into discontinuous roofing and external cladding.
For the purposes of BS EN 12326-1, slates and carbonate slates have been classified.
Note 1: BS EN 12326-1 does not apply to products for roofing or external cladding made from the following:
Note 2: BS EN 12326-1 is not applicable to roofing and cladding slates used internally.
Note 3: BS EN 12326-1 is not applicable to bonded cladding (cladding fixed with adhesives) and cladding fixed with dowels and cramps.
BS EN 12326-1 on slate and carbonate slate is useful for:
Slate roofs and clads are an excellent addition to any building structure because they provide an attractive and timeless appearance while offering adequate protection from extreme environmental conditions.
The petrographic examination and thickness or other dimensions of slates are specified in BS EN 12326-1. BS EN 12326-1 provides the best industry recommendations on product characteristics and includes procedures for testing, evaluation of conformity, marking, labelling and packaging of slate and carbonate slate. BS EN 12326-1 also covers guidance on Assessment and Verification of the Constancy of Performance (AVCP) that ensures your products conform with the requirements.
Thus, if you are a manufacturer of slate and carbonate slate products used for roofing and cladding, complying with BS EN 12326-1 can help demonstrate the performance of your product. You can ensure that your products are free from defects, offer adequate fire-resistance and provide long service-life irrespective of external weather conditions.
