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.
