ISO 9426 was prepared by Technical Committee ISO/TC 89, Wood-based panels. ii ISO 9426:2003(E) Introduction This seditionis based on European Standards sEN 324-1andEN 324-2. .Itcancels sand replaces IsO 9426-1:1989 which applied to the measurement of thickness, width and length. The scope was extended ISO 9426-2. Furthermore, the determination of flatness of panels was added. Compared to ISO 9426-1:1989, for the thickness measurement, a range has been specified for the anvil diameter and for the distance of measuring points, from the edges. @ ISo 2003 - All rights reserved itted without licensefrom IHS Not for Resale ISO 9426:2003(E) INTERNATIONAL STANDARD Wood-based panels Determination of dimensions of panels Scope This International Standard specifies methods for measuring the thickness, width and length, as well as the squareness, edge straightness and flatness of wood-based panels. It applies to full-size flat panels. Normative references The following referenced documents are indispensable for the application of this document. For dated document (including any amendments) applies. Iso 16999, Wood-based panels Sampling and cutting of test pieces 3 Principle The thickness, length and width of full-size panels are determined by linear measurement. Squareness and edge straightness of full-size panels are determined by the measurement of deviation from a mechanical square or s
