Wood-based panels — Dry-process fibreboard

This International Standard 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.

dry process fibreboard
wood fibreboard with a forming line moisture content, as a mass fraction, of less than or equal to 20 % and whose primary bonding results from applied adhesives or resins
wet process fibreboard
wood fibreboard with a forming line moisture content, as a mass fraction, of greater than 20 % and whose primary bonding results from felting of wood fibres and their
inherent adhesive properties
