标准摘要
[中文适用范围]： ISO 5350 的这一部分规定了一种通过透射光评估片材纸浆中可见污垢和碎片的方法。 它不适用于未漂白的牛皮纸浆或任何其他太不透明而无法根据 ISO 5350 的本部分估计最小尺寸或计算最小对比斑点的纸浆。 纸浆片材的重量范围为 800 g/m2 至 1 000 g/m2。 如果工厂片状纸浆的纸张克重较高或由于其他原因非常不透明，则应采用 ISO 5350-1。 注：对于具有高度纹理表面和/或密度变化的厚纸张，润湿纸张会导致光学变化，称为透镜畸变，这会扭曲污点的感知尺寸，从而降低尺寸估计的精度。 或者，使用 ISO 5350-1 分解纸张并准备实验室纸张以进行尺寸估计。 ISO 5350 的这一部分不适用于再生纸浆。 [外文原描述]： ISO 5350-2:2006 specifies a method for the estimation by transmitted light of the visible dirt and shives in pulp manufactured in sheets. It does not apply to unbleached kraft pulps or to any other sheeted pulps that are too opaque to allow for the estimation of the minimum size or for minimum contrast specks to be counted, in accordance with ISO 5350-2:2006. The maximum grammage for most pulp sheets is in the range 800 g/m 2 to 1 000 g/m 2 . If the sheets of the mill sheeted pulp have high grammage or are very opaque for other reasons, ISO 5350-1:2006 should be applied. ISO 5350-2:2006 is not intended for recycled pulp.
