This European Standard specifies the characteristics and performance of metal beads@ metal beads combined with paper tape and metal feature profiles designed for use in systems made with gypsum plasterboards according to EN 520@ gypsum boards with fibrous reinforcement according to EN 15283-1 and EN 15283-2 and products from secondary processing according to EN 14190@ gypsum board thermal/acoustic insulation composite panels according to EN 13950 and prefabricated gypsum board panels with a cellular paperboard core according to EN 13915@ intended to be used in building construction works. Metal beads and feature profiles@ depending upon their material and type@ can be featured without decoration@ decorated or finished with jointing compounds to receive decoration. It covers the following performance characteristics: reaction to fire and flexural strength (bending behaviour) to be measured according to the corresponding European test methods. It provides the assessment and verification of constancy of performance of the products This European Standard covers also additional technical characteristics that are of importance for the use and acceptance of the product by the construction industry and the reference tests for these characteristics.
