GB/T17657-2013 Test Method for Physical and Chemical Properties of Artificial Board and Decorative Artificial Board: Determination of Internal Bonding (Bonding) Strength. 11 Determination of internal bonding strength 11.1 Principle The internal bonding strength is a measurement of the tensile strength of the specimen surface to withstand uniformly distributed tensile force until failure. The internal bonding strength is the ratio of …

GB/T17657-2013 Test Method for Physical and Chemical Properties of Wood-based Panels and Decorative Wood-based Panels: Determination of Static Bending Strength and Elastic Modulus (Three Point Bending) Determination of static bending strength and elastic modulus (three-point bending) 7.1 Principle The static bending strength and elastic modulus of three-point bending are measured by applying a load to the middle of the specimen …

Detect the bending moment and flexural modulus ratio of artificial decorative panel panels under maximum load. Three point bending test steps for artificial decorative panels: Make the test piece according to the test requirements: Size and length of the test piece: (thickness of the test piece) × 20+50）mm； Width b=(50 ± 1) mm. For hollow structural plates with tube holes …
