Pulps -- Laboratory wet disintegration -- Part 2: Disintegration of mechanical pulps at 20 degrees C
In principle, this method is applicable to all kind of mechanical pulps (i.e. mechanical, semi-chemical and chemo-mechanical pulps) that do not exhibit latency, including recovered fibres from mechanical pulps. It is not suitable for mechanical pulps exhibiting latency for which the disintegration procedure described in ISO 5263-3 shall be used.
The procedure specified by ISO 5263-2:2004 should also be used to disintegrate all mechanical pulps to be measured for brightness.
