Pulps. Determination of lignin content. Acid hydrolysis method

PUBLISH DATE 2020
PAGES 22
BSI BS ISO 21436:2020

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.
