- Scope
- This standard specifies a method for determining the drainage capacity of pulp suspensions, expressed by the Schober-Rigler (sR) value. I This standard is applicable to various pulp suspensions, but for some pulps with extremely short fibers (such as heavy-beating hardwood pulp), because most of the fibers will pass through the filter screen, the SR value will decrease irregularly , so this method is not recommended. The vast majority of reliable measurement results should be in l10SR~90SR Note: The Canadian standard freeness method is described in detail in "Canadian Standard" Freeness Method for Determination of Pulp Drainage Performance.
