ISO 15319:1999 PDF

Scope: This International Standard specifies a method for the estimation of visible contraries in pulp by instrumental means using reflected light. This International Standard cannot be used for inspection of pulps of low brightness, i.e. for evaluation of light contraries in dark pulp. Spots which look brighter than the surrounding area due to fluorescence will not be detected by the method described in this International Standard. NOTE 1 The evaluation of contraries smaller than 0,04 mm is not covered by this International Standard. See informative annex A. NOTE 2 This International Standard is mainly intended for the assessment of product quality. Modifications may be needed if it is applied to process control.
