Paper and board - Automated off-line testing of physical properties for CD (cross direction) profiles

ISO 18522:2016 specifies the procedures for determining the cross direction profiles of physical properties of paper and board using automated off-line testers. Where available for a given measurement, the relevant International Standard is referred to. It is applicable to most kinds of paper and board, but is not relevant for tissue and corrugated board. In ISO 18522:2016, it is left to the paper and board producer and the customer to agree upon which properties are relevant. The results are reported as mean values or as profiles across the machine. Some properties are reported in index form. The result obtained using the relevant ISO standard based on stand-alone equipment is used in case of challenge or dispute, if not otherwise agreed.
