ISO/TC 89/SC 1 - Fibre boards

ISO 27769:2016 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.

ISO 17064:2016 provides definitions and terminology applying to all types of fibreboard, particleboard and oriented strand board (OSB).

ISO 16895:2016 specifies a classification matrix, related mandatory tests and thickness ranges for ultra-low-, low-, medium- and high-density dry process wood-based fibreboard. It then provides the manufacturing property requirements for these types of uncoated fibreboard. The values listed in this International Standard relate to product properties used to classify fibreboards into one of four types (UDF, LDF, MDF and HDF, see Clause 3), one of four grades (GP, FN, BL and LB), for use in one of four service conditions (REG, MR1, MR2, and HMR). The values are not characteristic values to be used for design purposes. NOTE Fibreboards are broadly divided into two groups based on the manufacturing process, namely the dry process group and the wet process group (see Clause 3). Wet process fibreboards lie outside the scope of this International Standard.

ISO 16895-2:2010 provides the manufacturing property requirements for uncoated dry-process fibreboard.

ISO 27769-1:2009 provides a classification matrix and related mandatory tests for two types of wet-process fibreboard: softboards and hardboards. NOTE 1 Wet-process fibreboards are divided into three types: softboards, medium boards and hardboards. NOTE 2 ISO 27769-1:2009 is not applicable to medium boards. NOTE 3 Fibreboards are broadly divided into two groups based on the manufacturing process, namely the dry-process group and the wet-process group. ISO 27769-1:2009 is not applicable to dry-process fibreboards (see ISO 16895-1 and ISO 16895-2).

ISO 27769-2:2009 specifies the manufacturing property requirements for wet-process fibreboard. NOTE The values listed in ISO 27769-2:2009 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.

ISO 16895-1:2008 specifies a classification matrix, related mandatory tests and thickness ranges for ultra-low-, low-, medium-, and high-density dry process fibreboard.

ISO 17064:2004 provides definitions and terminology applying to all types of fibreboard, particleboard and oriented strand board (OSB).

A method applying to hard fibre boards is specified, the principle of which consists in measuring the air escaping from measuring head placed on the surface of a test piece. Details of the apparatus are illustrated in figures and relevant values are given in a table.

Covers sheet materials as classified and defined in ISO 818. The specified method includes the calculation of the increase in mass and thickness. Apparatus, sampling and preparation of specimens, and testing are described.
