China's national standards of medium density fiberboard (GB / T 11718-2021) and veneer laminated wood (GB / T 20241-2021) will be implemented from June 1, 2022.


These two new standards are amendments to the standard (GB / T 11718-2009) and the standard (GB / T 20241-2006). Medium density fiberboard (MDF) is one of the main varieties of fiberboard in China, accounting for more than 80% of the total output of fiberboard in China. In 2020, China's medium density fiberboard output was 53.47 million cubic meters.


Since the release of GB / T 11718-2009 MDF in 2009, it has played an important role in standardizing the production of MDF and improving the quality of MDF products. In order to promote the further development of MDF industry, GB / T 11718-2021 standard has been partially revised according to international standards, and some technical contents have been revised.


Veneer laminated wood (LVL) is an important structural material, which is widely used in building I-beams, wood joists, door frames and furniture frames. Since the release of GB / T 20241-2006 LVL standard in 2006, the standard has played an important role in standardizing production, improving product quality and promoting the development of wood structure and packaging industry.


In the revision of GB / T 20241-2021, the relevant standards of ISO are adopted, and the relevant standards of Japan and the European Union are fully referred to.
