Paper is used for many and varying applications, each with a different set of requirements. Tissue needs to be soft and flexible, whereas cardboard needs to be stiff and have high compressive strength. Fibre furnish analysis is the determination of the fibre components of paper, board and pulp samples as regards the species of fibres and the method of processing.
BS 7463-1 is identical to ISO 9184-1. The BS 7463 series focuses on Fibre furnish analysis of paper, board and pulps. BS 7463-1 specifies the general performance of the test for fibre furnish analysis of paper, board and pulps.
BS 7463-1 is applicable to all kinds of pulps and to most papers and boards, including those containing more than one kind of fibre, taking into account different pulping processes. Fibre analysis of paper and paperboard is less suitable for heavily impregnated or highly coloured papers and boards, which cannot be dispersed or decoloured without affecting the structure or the staining reactions of the fibres.
BS 7463-1 on paper fibre analysis is useful for:
Fibre furnish analysis provides a procedure for the identification of the kinds of fibres present in a sample of paper or paperboard and their quantitative estimation. The main purpose of doing fibre and pulp analysis is to identify the fibre and pulp types.
Fibre furnish analysis depends on the type of pulp, the colour differences obtained, the accuracy of the weight factors used, and the judgement of the analyst. The fibre furnish analysis is carried out under the microscope on a small quantity of stained fibres. BS 7463-1 provides you with quantitatively and qualitatively methods for the analysis of fibre furnish of paper, board and pulps.
Overall, BS 7463-1 helps you for the identification of the kinds of fibres present in a sample of paper or paperboard with guidance on fibre analysis of paper and board.
