Scope: This document provides a classification matrix and related mandatory tests for two types of wet process fibreboard made from wood: softboards and hardboards and specifies the relevant manufacturing property requirements. NOTE 1 Wet process fibreboards are divided into three types: softboards, medium boards and hardboards. This document is not applicable to medium boards. NOTE 2 Fibreboards are broadly divided into two groups based on the manufacturing process, namely the dry-process group and the wet process group. This document is not applicable to dry-process fibreboards (see NOTE 3 The values listed in this document relate to product properties used to classify fibreboards into one of the different types. The values are not characteristic values to be used for design purposes. When fibreboard is classified as load-bearing and nominated for structural applications, characteristic strength and stiffness values are established based upon testing in accordance with ISO 16572 or equivalent ASTM or EN Standards. Alternatively, for specific load-bearing applications (e.g. walls, roofs, floors and I-joist webs), the load-bearing fibreboard would meet the specific performance requirements for that intended application.
