國家標準化管理委員會發(fā)布2014年第11號公告，批準發(fā)布推薦性國家標準GB/T 30735-2014《屋頂及屋頂覆蓋制品外部對火反應(yīng)試驗方法》。該標準為首次發(fā)布，將于2014年10月1日起實施。
國家標準化管理委員會發(fā)布2014年第11號公告，批準發(fā)布推薦性國家標準GB/T 30735-2014《屋頂及屋頂覆蓋制品外部對火反應(yīng)試驗方法》。該標準為首次發(fā)布，將于2014年10月1日起實施。
標準規(guī)定了建薇屋頂或屋頂覆蓋制品在外部火源作用條件下的對火反應(yīng)試驗方法，該方法在編制時對比了國際現(xiàn)有的試驗方法特點，在技術(shù)內(nèi)容上主要參照ISO和EN標準，結(jié)合我國建筑屋頂及屋頂系統(tǒng)制品的應(yīng)用現(xiàn)狀，考慮來自于上部建筑或鄰近建筑的燃燒碎片、飛火和熱輻射等作用，模擬其對火反應(yīng)條件，通過大量的試驗驗證，對屋頂外部對火反應(yīng)試驗方法進行了詳細規(guī)定。
該標準由公安部四川消防研究所負責起草，全國消防標準化技術(shù)委員會防火材料分技術(shù)委員會（SAC/TC 113/SC7）歸口。該標準的頒布實施，為建筑材料燃燒性能分級標準及建筑防火設(shè)計規(guī)范的制修訂提供了證據(jù)，為建筑屋頂制品燃燒性能研究和測試提供了評價手段，對推動屋頂產(chǎn)品技術(shù)的發(fā)展，指導(dǎo)工程實際應(yīng)用具有積極意義。
