纸浆、纸和纸板 纤维组成分析 第7部分:权重因数测定

[中文适用范围]： 规定了两种用于确定纸张、纸板和纸浆的纤维配料分析中使用的纤维重量系数的方法：通过与参考纸浆进行比较（任何仅包含一种类型明确纤维的纸浆 - 机械纸浆和打浆纸浆是不合适的） ，且其权重因子已知）或通过纤维粗度计算。 这些方法适用于来自未混合木种的各种纸浆纤维，这些纤维含有不超过 5% 的重量因子本质上不同的其他纤维。 [外文原描述]： Specifies two methods for determining the weight factor of fibres used in the fibre furnish analysis of paper, board and pulp: by comparison with a reference pulp (any pulp that contains only one type of well-defined fibre - mechanical pulps and beaten pulps are unsuitable, and whose weight factor is known) or by calculating from the fibre coarseness. The methods are applicable to all kinds of fibres of pulp from unmixed wood species which do not contain more than 5% of other fibres with an essentially different weight factor.
