标准摘要
[中文适用范围]： 本部分规定了格拉夫“C”染色剂的制备、使用和显色反应。 它应与 ISO 9184-1 结合使用，如有必要，还应与 ISO 9184-2 中定义的其他染色测试结合使用。 格拉夫“C”染色剂可以识别几乎所有常见的造纸纤维。 然而，这需要大量的培训和经验。 因此，主要应用有：化学浆、半化学浆和机械浆的区分，阔叶木浆中牛皮纸浆和亚硫酸盐的区分，针叶木浆和阔叶木浆（溶解级浆除外）的区分，针叶木浆中漂白草浆和浓缩浆的区分。 [外文原描述]： This part specifies the preparation, use and colour reactions of Graff "C" stain. It should be used in conjunction with ISO 9184-1 and, if necessary, with other staining tests defined in ISO 9184-2. Graff "C" stain allows the identification of almost all the common papermaking fibres. However, this calls for a great deal of training and experience. Thus, main applications are: differentiation of chemical, semi-chemical and mechanical pulps, differentiation of kraft and sulfite in hardwood pulps, differentiation of softwood and hardwood pulps (except dissolving grade pulps), differentiation of bleached straw and esparto pulps in softwood pulps.
