Pulp properties measured in wet state Freeness and pH The freeness level of fluff pulps is usually 650–700 CSF. Freeness measurement uses the Canadian Standard freeness method according to the ISO 5267-2. Before the freeness measurement, the pulp undergoes disintegration by a hot or cold technique, ISO 5263-3 or -1 respectively. The pH of the
