该方法用于测定高锰酸钾值低于35的化学浆（l）的相对“硬度”或可漂白性。这种有用的方法在一个过程中包括两种变化。一种方法是用于高锰酸钾值小于20的低木质素含量纸浆；第二个步骤是用于高锰酸盐值在20到35之间的高木质素含量纸浆。对于高锰酸盐值大于35的纸浆，使用TAPPI T 236“纸浆卡伯值”

This method provides for the determination of the relative "hardness" or bleachability of chemical pulps (l) having a permanganate number below 35.This Useful Method covers two variations in a single procedure. One procedure is for low lignin content pulps having a permanganate number less than 20; and a second procedure is for higher lignin conent pulps having permanganate numbers between 20 and 35. For pulps above permanganate number of 35, use TAPPI T 236 "Kappa Number of Pulp."
