Papier, carton et pâtes — Détermination de la composition fibreuse — Partie 6: Détermination de la masse linéique des fibres

Specifies a method for determining fibre coarseness (which is a fibre property characterizing pulp): distribution of a known mass of fibres evenly over a known area, counting the number of fibre crossings along a line of known length on a microscope slide. The weight factor can be calculated from the fibre coarseness. The method is applicable to pulps with relatively intact fibres, such as chemical and semichemical pulps. Does not apply to mechanical and semimechanical pulps or highly beaten chemical or semichemical pulps.
