+AMD1:2003 CSV 火灾危险测试 第11-10部分：测试火焰 50 W 水平和垂直火焰测试方法

[中文适用范围]： 规定了小规模实验室筛选程序，用于比较由塑料和其他非金属材料制成的垂直或水平定向样本暴露于 50 W 标称功率的小火焰点火源的相对燃烧行为。这些测试方法确定线性燃烧速率和余焰/余辉时间，以及样品的损坏长度。适用于表观密度不低于 250 kg/m3（根据 ISO 845 测定）的固体和多孔材料。它们不适用于在不点燃的情况下收缩远离施加火焰的材料； ISO 9773 应用于薄柔性材料。所描述的测试方法提供了可用于质量保证或产品成分材料预选的分类系统。可用于材料的预选，前提是在厚度等于应用中使用的最小厚度时获得积极的结果。根据指南 104，具有基本安全出版物的地位。该合并版本由第一版 (1999 年) 及其修订版 1 (2003 年) 组成。因此，无需对本出版物进行修订。 [外文原描述]： Specifies a small-scale laboratory screening procedure for comparing the relative burning behaviour of vertically or horizontally oriented specimens made from plastic and other non-metallic materials, exposed to a small-flame ignition source of 50 W nominal power. These test methods determine the linear burning rate and the afterflame/afterglow times, as well as the damaged length of specimens. Applicable to solid and cellular materials that have an apparent density of not less than 250 kg/m3, determined in accordance with ISO 845. They do not apply to materials that shrink away from applied flame without igniting; ISO 9773 should be used for thin flexible materials. The test methods described provide classification systems which may be used for quality assurance, or the pre-selection of component materials of products. May be used for the pre-selection of a material, providing positive results are obtained at a thickness equal to the smallest thickness used in the application. Has the status of a basic safety publication in accordance with Guide 104. This consolidated version consists of the first edition (1999) and its amendment 1 (2003). Therefore, no need to order amendment in addition to this publication.
