This part of ISO 801 specifies a method for determining the dryness of a lot of pulp baled in slabs and for calculating its saleable mass. This method is applicable to most kinds of pulp, in bales of approximately 200 kg, and made up of four to six slabs or wads, of fairly uniform and similar thickness. It may also be applicable to bales not composed of individual layers, but which are naturally delaminateable. It does not apply to pulp baled in sheet form or to pulp in unitized bales. The method is not applicable if the drilling device becomes appreciably hot because of frictional heat evolved during drilling; this can occur with some strong chemical or semichemical pulps. An example of a full certificate of analysis and related calculations is given in annex A.
