This part of ISO 5350 specifies a procedure for the estimation of the visible dirt and shives by reflected light using the Equivalent Black Area (EBA) method in pulps. It is, in principle, applicable to all types of dry or wet pulp, manufactured in sheets or rolls, including recycled pulp.NOTE The result of inspection by reflected light represents only the number of specks visible on the surface or near the surface of the pulp sheet. Particles which are embedded in the sheet cannot be detected.
