本欧洲标准规定了金属珠，与纸带结合的金属珠和金属特征轮廓的特性和性能，该特征和金属特征轮廓设计用于根据EN 520的石膏板制成的系统，具有根据EN 15283 1和EN 15283 2的纤维增强材料的石膏板和根据EN 14190的二次加工产品，根据EN 13950的石膏板热隔音复合板和具有根据EN 13915的蜂窝纸板芯的预制石膏板面板，用于建筑施工。金属珠和特征轮廓，根据其材料和类型，可以没有装饰，装饰或完成与接合化合物接收装饰。 它涵盖以下性能特点:根据相应的欧洲测试方法测量的反应和火焰和弯曲强度（弯曲行为）。 它提供产品性能稳定性的评估和验证 本欧洲标准还包括对建筑业对产品的使用和验收以及这些特性的参考试验具有重要意义的其他技术特性

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.
