BS ISO 19821:2017规定了确定天然纤维增强塑料跨度额定值的程序 复合（NFC）桥面板和用作楼梯踏板的桥面板，前提是楼梯踏板 采用与甲板板相同的材料和加工工艺生产。本文件涵盖 性能试验方法、验收标准和跨度额定值的确定。其目的是 建立外部应用中使用的甲板的代码识别基础 允许施工。交叉引用:ISO 16616:2015EN 15534-1:2014ISO 4892-2:2013ASTM D7032-17ISO 291No I.C.C.-E.S.174ISO 15270No I.C.C.-E.S.109购买本文件时可提供的所有现行修订均包含在购买本文件中。

BS ISO 19821:2017 specifies the procedures to establish a span rating for natural fibre-reinforced plastic composite (NFC) deck boards and deck boards used as stair treads, provided that the stair treads are produced from the same materials and processing techniques as the deck boards. This document covers test methods of performance, acceptance criteria and determination of span rating. It is intended to establish the basis for code recognition of deck boards used in exterior applications where combustible construction is allowed.Cross References:ISO 16616:2015EN 15534-1:2014ISO 4892-2:2013ASTM D7032-17ISO 291No I.C.C.-E.S. 174ISO 15270No I.C.C.-E.S. 109All current amendments available at time of purchase are included with the purchase of this document.
