EN2825煙霧密度測定
EN2824-EN 2825-EN2826煙密度和煙氣成分分析 - 標(biāo)準(zhǔn)簡介
EN2824定義了測試設(shè)備,裝置和介質(zhì),根據(jù)EN2825測定煙霧密度和根據(jù)EN 2826測定煙霧中氣體成分濃度,由于在輻射熱影響下或同時(shí)使用火焰時(shí),厚度高達(dá)25 mm的固體材料和復(fù)合材料會(huì)發(fā)生熱解分解。
Definesthe test e, apparatus and media required for determination of the smokedensity according to EN 2825 and the concentration of the gas components in thesmoke according to EN 2826 due to pyrolitic decomposition of solid materialsand composite materials of up to 25 mm in thickness under the influence ofradiant heat only or with simultaneous flame application.
