ISO 15025:2016规定了两种程序（表面点火和底边点火），用于测定单组分或多组分织物（涂层、绗缝、多层、夹层结构和类似组合）形式的垂直定向柔性材料在受到小火焰时的火焰传播特性。本试验标准不适用于空气供应受限或暴露于大热源的情况，其他试验方法更适用于这些情况。 本试验方法不适用于表现出广泛熔化或收缩的材料。

ISO 15025:2016 specifies two procedures (surface ignition and bottom-edge ignition) for determining flame spread properties of vertically oriented flexible materials in the form of single or multicomponent fabrics (coated, quilted, multilayered, sandwich constructions and similar combinations), when subjected to a small defined flame. This test standard does not apply to situations where there is restricted air supply or exposure to large sources of intense heat, for which other test methods are more appropriate. This test method is not appropriate for materials that demonstrate extensive melting or shrinkage.
