The Kappa number describes the lignin content or bleachability of pulp. With this test, the kappa number is determined as per the ISO 302 standard, which applies to all kinds of chemical and semi-chemical pulps within a Kappa number range from 1 to 100.

For pulps with higher Kappa numbers, the ISO 3260 procedure is recommended.
