Paper, board and pulps -- Fibre furnish analysis -- Part 3: Herzberg staining test
This standard was last reviewed and confirmed in 2016. Therefore this version remains current.
This part specifies the preparation, use and colour reactions of Herzberg stain. It should be used in conjunction with ISO 9184-1 and, if necessary, with other staining tests defined in ISO 9184-2. The Herzberg staining test is applicable to the qualitative and quantitative differentiation between chemical, mechanical and rag pulps. The stain also permits the qualitative identification of semi-chemical pulp as well as the differentiation between regenerated cellulose fibres (viscose, etc.) and synthetic fibres.
