Product Standards & Certification
No current British or European standard exists for single ply roofing systems. In the absence of a standard, the Building Regulations require independent certification of a product, currently by either The British Board of Agrement (BBA) or BRE Certification.
Both bodies certificate single ply material and systems, based upon test methods that have a commonality throughout the EEC. Their investigations focus on the confirmation of a manufacturer’s own test data, with limited testing conducted independently. On the basis of this, independent test data and the as-built history of the product, certification bodies will provide a statement of the anticipated durability of the product provided it is installed in accordance with the manufacturer’s instructions.
The SPRA is actively involved with the British Standards Institute (BSI), the European Committee for Standardisation (CEN) and the British Board of Agrément (BBA), to ensure that authorised minimum standards exist throughout Europe for single ply roofing materials. The harmonised European Standard EN13956 is due for implementation in 2005. This standard will set rules for the declaration of product characteristics against a list of pan-European Standard test methods. This will facilitate the comparison between products of different national origin. However, this Standard will set requirements only in respect of fire performance (a full system test - see 3.12 above) and watertightness.
The designer should consult manufacturers and SPRA for advice on the relevance of different product characteristics to a particular project.
