Dirt quantification for bleached kraft pulp with a web inspection system using transmitted light
This document describes guidelines and recommended practices for the detection and quantification of dirt specks in a moving sheet of bleached kraft pulp using light transmitted through the pulp sheet. Dirt speck results are reported as “physical” size and not as the Equivalent Black Area (EBA) of the laboratory standard method T563, which must be measured with reflected light (Ref. 1)
