GB/T 17657-2013 "Test method for physical and chemical performance of wood-based panels and veneer wood-based panels" is a revised version of GB/T 17657-1999 standard. 17 test methods have been added to this standard, such as method for measuring the thickness expansion rate of water absorption 2, method for measuring the curvature strength after immersion treatment after the determination of static bending strength and resilience modulus, test for moisture-proof performance Boiling test, and test for disbonding resistance. At the same time, 4 test methods have been deleted, such as the determination of ultimate volume expansion rate and Hardness measurement. The main revisions include the measurement of specimen size, the modification of thickness measurement terms, and the adjustment of density measurement and moisture content measurement. The purpose of this standard is to provide a more accurate and comprehensive method for evaluating the physical and chemical performance of wood-based panels to support the improvement of product mass and the needs of technology research and development.
