    22、:2016(E)IntroductionThe automated off-line testing of cross direction (CD) profiles of paper and board was introduced in the 1980s. The apparatus available then was equipped with various modules for the determination of basic physical properties such as grammage, thickness, Bendtsen roughness, air p

    23、ermeance, etc. In the 90s, more advanced modules were developed for tensile, tear and bending testing. Modules for the measurement of the optical properties with the C/2, D50/2 and D65/10 illuminants are also available.The principal benefits of automated off-line testing are the speed with which the

    24、 results are obtained and the small number of staff required to operate the testing apparatus.Testing with stand-alone instruments implies much longer time before the results are available. Automated off-line testing improves the repeatability in testing as the operator dependency disappears.In most

    25、 of the countries producing paper and board, some type of automated off-line testing of CD profiles is carried out.For the determination of physical properties, this document refers, where possible, to the relevant International Standards for the description and calibration of the equipment required

    26、. The results from automated off-line testing are widely accepted by the customers although the conditioning requirements stated in ISO 187 are not met.vi ISO 2016 All rights reservedBS ISO 18522:2016Paper and board Automated off-line testing of physical properties for CD (cross direction) profiles1

    27、 ScopeThis 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 a

    28、nd 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 fo

    29、rm.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

    30、 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 Ann

    31、ex B.NOTE 2 It is also possible to evaluate properties in the machine direction (MD), but this is usually only used for trouble-shooting.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document

Means may be provided for controlling the sample and feeding it to the test line, such as automated winding of the CD sample onto a removable cylinder which can be inserted in the automated off-line tester.5.1.2 It is possible to use manual sample cutters. The sample can be

They are typically composed of an unwind

Some test lines are equipped with a moisture content module providing the possibility of correcting the values if needed.Some of the test methods are not the same as those in the equivalent reference standards for stand-alone instruments.
