ASTM D4986多孔聚合材料水平燃燒 – 適用范圍
本防火試驗(yàn)響應(yīng)標(biāo)準(zhǔn)包含一種小型實(shí)驗(yàn)室程序的試驗(yàn)方法，用于測(cè)定密度小于250 kg/m3的水平定向多孔聚合材料的相對(duì)燃燒速率、燃燒程度和燃燒時(shí)間。

結(jié)果旨在作為一個(gè)初步的跡象，表明它們?cè)谔囟☉?yīng)用中的可育性方面的可接受性。材料的最終驗(yàn)收取決于其在最終產(chǎn)品中的使用，并符合適用于此類最終產(chǎn)品的標(biāo)準(zhǔn)。

附錄XI中描述的分類系統(tǒng)用于質(zhì)量保證和產(chǎn)品組件材料的預(yù)選。

本標(biāo)準(zhǔn)測(cè)量并描述了材料、產(chǎn)品或組件在受控條件下對(duì)熱量和火焰的響應(yīng)，但其本身并未包含實(shí)際火災(zāi)條件下材料、產(chǎn)品或組件火災(zāi)危險(xiǎn)性評(píng)估所需的所有因素。

This fire-test-response standard contains a test method for small-scale laboratory procedures to be used to determine the relative rate of burning and the extent and time of burning of horizontally oriented cellular polymeric materials having a density less than 250 kg/m3.

The results are intended to serve as a preliminary indication of their acceptability with respect to flammability for a particular application. The final acceptance of the material is dependent upon its use in the end-product that conforms with the standards applicable to such end-product.

The classification system described in the Appendix XI is intended for quality assurance and the preselection of component materials for products.
