标准摘要
[中文适用范围]： 本文件规定了厚度不超过 20 毫米（含 20 毫米）的软质聚氨酯泡沫的最低要求，旨在与合适的基材（如无纺布、机织布或针织物）组合形成层压板。 软质聚氨酯泡沫塑料的三种类型规定如下： ——类型 1：聚醚； ——类型 2：最小断裂伸长率为 200% 的聚酯； ——类型 3：最小断裂伸长率为 300% 的聚酯。 [外文原描述]： This document specifies the minimum requirements for flexible polyurethane foams up to and including 20 mm thick intended for combination with suitable substrates such as non-woven, woven or knitted fabrics, to form a laminate. Three types of flexible polyurethane foam are specified as follows: — type 1: polyether; — type 2: polyester with minimum elongation at break of 200 %; — type 3: polyester with minimum elongation at break of 300 %.
