规定了一种小规模实验室筛选程序，用于比较塑料和其他非金属材料制成的试样的相对燃烧行为，以及它们在暴露于500 W标称功率的火焰点火源时的耐烧穿性。根据ISO 845测定时，该方法适用于表观密度为250 kg/m3或以上的固体材料和多孔塑料材料。它不适用于在不点火的情况下远离火焰收缩的薄材料，应使用ISO 9773。所述试验方法旨在表征材料性能，例如用于质量控制目的，而不是评估建筑材料或家具的防火性能。它可以用于预处理- 选择一种材料，前提是在厚度等于应用中使用的最小厚度时获得积极结果。所获得的结果提供了有关塑料材料在使用中的行为的一些信息，但其本身无法确保在使用中的安全性能。本试验方法提供了一个分类系统，可用于质量保证或产品组成材料的预选。 具有指南104规定的基本安全出版物的状态。

Specifies a small-scale laboratory screening procedure for comparing the relative burning behaviour of specimens made from plastics and other non-metallic materials, as well as their resistance to burn-through when exposed to a flame ignition source of 500 W nominal power. This method is applicable to both solid materials and cellular plastic materials having an apparent density of 250 kg/m3 or greater when determined in accordance with ISO 845. It does not apply to thin materials that shrink away from the applied flame without igniting, for which ISO 9773 should be used. The test method described is intended to characterize material performance, for example for quality-control purposes, and is not intended to assess the behaviour to fire of building materials or furnishings. It may be used for the pre-selection of a material, provided that positive results are obtained at a thickness which equals the smallest thickness used in the application. The results obtained provide some information about the behaviour of plastic materials in service, but can never by themselves assure safe performance in service. This test method provides a classification system which may be used for quality assurance or the pre-selection of component materials of products. Has the status of a basic safety publication in accordance with Guide 104.
