标准摘要
[中文适用范围]： 与两种类型的片材相关：开孔材料和闭孔材料。 它们根据硬度指数分级。 对于类型 1 片材，指定了单一硬度级别，但对于类型 2 片材，指定了一个范围。 对于最大约 100 毫米的片材，规定了材料压痕硬度指数。 对于2型，其厚度大多小于50mm，需要使用由多层组成的试件，因此规定了产品压痕硬度指标。 关于有机材料染色的附件。 [外文原描述]： Related to two types of sheetings: open cell material and closed cell material. They are graded according to hardness index. For type 1 sheeting a single hardness level is specified, but for type 2 sheeting a range. For sheeting up to approximately 100 mm the material indentation hardness index is specified. For type 2, mostly available in thicknesses much less than 50 mm, it is necessary to use a test piece consisting of a number of plies, therefore the product indentation hardness index is specified. An annex about organic materials staining.
