NBN ISO 16895:2021

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.
