Scope

This standard specifies the determination method of pulp a cellulose. This standard is only applicable to the determination of bleached pulp or delignified pulp. For unbleached pulp and semi-bleached pulp, the lignin must be removed before the test. The method of delignification can refer to the method of GB2677.10 "Determination of cellulose content in papermaking raw materials".
