BS EN 1794-3:2016旨在提供有关 降噪装置中使用的材料对火灾、烟雾密度和有毒烟雾的反应。灌木丛火灾试验、烟雾密度试验和有毒烟雾试验的组合给出了一般性结论 足够的安全信息。本欧洲标准还提供了更严格的信息 要求更高安全级别的情况。对于降噪装置，本欧洲标准给出了处理大量噪声的方法 非专利产品的组成部分- 同质产品（定义见EN 13501-1和ISO/DIS 5659-2:2016）和 如何处理非同质产品，在哪些情况下非同质产品的影响很大 分类总结果中的成分可能会被忽略。将考虑以下影响:可燃性、燃烧液滴、烟雾增长率、， 烟雾密度，有毒烟雾。欧盟委员会第96/603/EC号决定确定了属于A类产品的清单 “对火灾的贡献”。本附录中列出的材料和由其制成的产品 鉴于其燃烧性水平较低，且符合本协议中规定的条件，将做出决定 附件应按照本附件表1和表2的规定分类为A1类和A1FL类 第2000/147/EC号决定。就本分类而言，对这些材料的燃烧试验无反应 需要使用由其制成的材料和产品。这些产品被认为对经济没有贡献 本标准不包括火灾。交叉引用:EN 1363-1:2012EN 13501-1:2007+A1:2009EN 13823EN ISO 11925-2ISO 11925-2ISO/DIS 5659- 2:2016EN 1793-1EN 1793-2EN 1793-6EN 13501EN 14389-1EN ISO 291ISO 291EN ISO 1182ISO 1182EN ISO 1716ISO 171696/82/EC96/603/EC2000/147/E购买本文件时提供的所有现行修订均包含在购买本文件中。

BS EN 1794-3:2016 is to give authorities, designers and specifiers information with respect to reaction to fire, smoke density and toxic fumes of materials used in noise reducing devices.The combination of brushwood fire test, smoke density test and test for toxic fumes give in general enough safety information. This European Standard gives also information if more stringent requirements are requested for situations with a higher level of safety.For noise reducing devices, this European Standard gives a method how to handle substantial components of non-homogeneous products (as defined in EN 13501-1 and ISO/DIS 5659-2:2016) and how to handle non-homogeneous products and in which cases the influence of non-substantial components on the total result of the classification may be neglected.The following effects will be taken into account: ignitability, burning droplets, smoke growth rate, smoke density, toxic fumes.The European Commission Decision 96/603/EC establish the list of products belonging to Classes A 'No contribution to fire'. The materials, and products made from them, that are listed in the Annex to this Decision, will, on account of their low level of combustibility and subject to the conditions also set out in the Annex, be classified in Classes A1 and Class A1FL as provided for in Tables 1 and 2 of the Annex to Decision 2000/147/EC. For the purpose of this classification, no reaction-to-fire testing of those materials and products made from them is required. The products considered having no contribution to fire are excluded from this standard.Cross References:EN 1363-1:2012EN 13501-1:2007+A1:2009EN 13823EN ISO 11925-2ISO 11925-2ISO/DIS 5659-2:2016EN 1793-1EN 1793-2EN 1793-6EN 13501EN 14389-1EN ISO 291ISO 291EN ISO 1182ISO 1182EN ISO 1716ISO 171696/82/EC96/603/EC2000/147/ECAll current amendments available at time of purchase are included with the purchase of this document.
