DESCRIPTION
BS 7463-3:1991
This standard BS 7463-3:1991 Fibre furnish analysis of paper, board and pulps is classified in these ICS categories:
- 85.040 Pulps
- 85.060 Paper and board
This part of ISO 9184 specifies the preparation, use and colour reactions of Herzberg stain in fibre furnish analysis. 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.
