Paper, board and pulps -- Fibre furnish analysis -- Part 7: Determination of weight factor
This standard was last reviewed and confirmed in 2017. Therefore this version remains current.
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.
