DESCRIPTION

BS ISO 21436:2020


This standard BS ISO 21436:2020 Pulps. Determination of lignin content. Acid hydrolysis method is classified in these ICS categories:
  • 85.040 Pulps

The method is applicable to unbleached, bleached and semi-bleached wood pulp with a lignin content above 1 %. It is not generally intended for fully bleached chemical pulp, because the lignin content in these pulps is too low to be determined accurately.
