ISO 5350-2:2006 specifies a method for the estimation by transmitted light of the visible dirt and shives in pulp manufactured in sheets. It does not apply to unbleached kraft pulps or to any other sheeted pulps that are too opaque to allow for the estimation of the minimum size or for minimum contrast specks to be counted, in accordance with ISO 5350-2:2006. The maximum grammage for most pulp sheets is in the range 800 g/m2 to 1 000 g/m2. If the sheets of the mill sheeted pulp have high grammage or are very opaque for other reasons, ISO 5350-1:2006 should be applied.ISO 5350-2:2006 is not intended for recycled pulp.
