英文名称：Paper and board — Automated off-line testing of physical properties for CD (cross direction) profiles

发布日期：2016-11

标准范围

This document 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 this document, 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.NOTE 1 The results obtained using specimens conditioned according to ISO 187 and stand-alone test instruments will, for some paper properties, differ from those obtained with unconditioned specimens and automated off-line testers. An investigation was made to only a limited extent, where the automated off-line testing was compared to stand-alone instruments, including the impact of conditioning. A summary of this investigation is reported in Annex B.NOTE 2 It is also possible to evaluate properties in the machine direction (MD), but this is usually only used for trouble-shooting.
