Pulps — Determination of lignin content — Acid hydrolysis method
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.
Material declaration for products of and for the electrotechnical industry
IEC 62474:2018+A1:2020 specifies the procedure, content, and form relating to material declarations for products of companies operating in and supplying the electrotechnical industry.
