Quality Standards For Solid Wood Boards

The quality standards of solid wood boards mainly include the following aspects:

‌Moisture content‌: Moisture content is a key indicator to ensure the stability and performance of the board, and should usually be controlled between 6-11%.
‌Transverse static bending strength‌: reflects the ability of the board to withstand bending loads and is an important indicator to measure the mechanical properties of the board.
‌Impregnation peeling performance‌: evaluates the bonding performance of the board after impregnation to ensure the stability of the board in a humid environment.
‌Surface bonding strength and bonding strength‌: measures the bonding quality of the board surface and the whole to ensure that the board is not easy to debond during use.
‌Formaldehyde emission‌: related to indoor environmental safety, it should comply with GB 18580-2017 standards, usually ENF grade formaldehyde emission ≤0.025mg/m³, E0 grade ≤0.05mg/m³, E1 grade ≤0.124mg/m³.
‌Appearance quality‌: check whether the surface of the board is flawless, including smoothness, flatness and color consistency.
‌Size and flatness‌: Ensure that the board meets the standard size and the surface is flat and flawless‌.
‌Verticality and edge straightness‌: Measure the verticality and edge straightness of the board to ensure the accuracy during installation‌.
‌Waviness‌: Inspect the ripples on the surface of the board to ensure the aesthetics‌.
‌Thickness‌: Check whether the thickness of the board meets the standard to ensure quality‌.
‌Environmental standards to pay attention to when choosing solid wood boards‌:

‌Environmental protection level‌: Choose products that reach ENF level or E0 level. These levels have lower formaldehyde emissions and are safer to use‌.
‌Ratio of solid wood core‌: A true multi-layer solid wood board should be composed of 100% solid wood core, and strictly selected hard eucalyptus wood should be used‌.
‌Resistance to cold and hot cycles‌: An excellent multi-layer solid wood board should be able to withstand a temperature difference of 100°C to ensure the load-bearing, deformation resistance and crack resistance of the board‌.
