GB/T 29418-2023 Test methods for properties of wood-plastic composite profile
Basic Information
Scope
This document specifies the test methods for plastic-wood composite extruded profiles, including sample handling, dimensional specifications and linear deviations, mass per meter length, bending, compression, shear strength, density, drop hammer impact, nail holding strength, moisture content, water absorption, water absorption thickness expansion, anti-slip value, wear resistance, creep recovery, creep failure, linear thermal expansion coefficient, freeze-thaw, high and low temperature resistance, boiling water resistance, aging, and anti-mildew. This document is applicable to plastic-wood composite extruded products, including surface co-extruded profile products. Products made by other molding methods can also refer to and use these test methods for reference.
