This Standard specifies dimensional tolerances and physical and mechanical properties for mat-formed medium density fibreboard (MDF), which is classified into standard, high moisture resistant and treated MDF. Appendices provide information on methods of compliance, purchasing guidelines, storage and handling, size or pack quantity combinations, and selection and application of screw fasteners.

This Standard specifies tolerances on dimensions, and physical and mechanical properties for mat-formed medium density fibreboard.NOTES:1 Alternative methods for demonstrating compliance with this Standard are given in Appendix A.2 Appendix B lists information that should be supplied by the purchaser at the time of inquiry or order.3 Appendix C describes recommended practices for the handling and storage of medium density fibreboard.4 Appendix D provides information on preferred sheet dimensions and pack quantities.5 Appendix E describes recommended practices for selection and application of screw fasteners.
