本文件规定了一种试验方法，用垂直定向试样，在零外加辐照度下，通过直接小火焰冲击测定产品的可燃性。 附录A（资料性附录）中给出了试验方法的精度信息。 附录B（规范性附录）中给出了非基本平端用途产品的测试信息。 附录C（规范性附录）中给出了穿孔终端产品的测试信息。

This document specifies a method of test for determining the ignitability of products by direct small flame impingement under zero impressed irradiance using vertically oriented test specimens. Information on the precision of the test method is given in Annex A (informative). Information on testing not essentially flat end-use products is given in Annex B (normative). Information on testing perforated end-use products is given in Annex C (normative).
