Scope

Scope: This standard specifies the terms and definitions, classification, requirements, sample collection and dimensions of medium-density fiberboard (MDF), as well as testing methods, inspection rules, and marking, packaging, transportation, and storage. This standard applies to MDF produced by the dry process. Note: The product performance requirements specified in this standard are not intended as characteristic values for engineering design applications. If MDF is classified as a load-bearing board or designated for use in building structures, or is substituted for specific load-bearing purposes, its relevant characteristic performance should also comply with the requirements of relevant national standards (specifications). Main technical content: The group standard for MDF is based on GB/T 11718-2009 "Medium-density fiberboard", GB 18580-2017 "Limit value of formaldehyde emission from interior decoration materials - Particleboard and its products", T/CNFPIA 1001-2016 "Limit value of formaldehyde emission from particleboard", and T/CNFPA 3002-2018 "Formaldehyde-free particleboard and its products". On the premise that technical indicators such as appearance quality, density and density deviation within the board, moisture content, static bending strength, elastic modulus, internal bond strength, surface bond strength, water absorption and thickness expansion, and physical and mechanical properties meet the requirements of national standards, the limit value of formaldehyde emission is set more strictly, and formaldehyde emission is divided into two grades: formaldehyde-free and E0. Additionally, the standard adds a limit value for TVOC.
