ISO/TS 20460:2015

ISO/TS 20460:2015 establishes guidelines to link and, where applicable, calibrate the online gauge, following laboratory measurement for a given paper and board property.
Paper and board online measuring equipment is mostly based on different technology to that of laboratory equipment. Therefore, this Technical Specification specifies the International Standards to be chosen for the determination of physical properties of paper and board when measured online. It is applicable to all kind of paper and board.
In case of dispute, the usual reference is the laboratory testing but the parties may decide that the online measurements are valid based on the application of this International Standard.
