scope:

This Standard specifies a method for determination of the drainability of a pulp suspension in water in terms of the "Canadian Standard" freeness in millilitres. In principle, this method is applicable to all kinds of pulp in aqueous suspension.

NOTE 1 Treatments which produce a large proportion of fines may induce an anomalous rise in freeness (false freeness), as a rule at values below 100 ml.

NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows :

ISO 5267-2 : 2001 Pulps - Determination of drainability - Part 2 : "Canadian Standard" freeness method (MOD)

The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.
