ASTM D7031 computerized wood-plastic material universal tester

1. Introductions

ASTM D7031 computerized wood-plastic composite products universal testing machine equipped with 3 and 4 point bending test attachment, compression test attachment, nail holding power test attachment, can be used to measure and determine bending force, bending strength, modulus of elasticity in bending, compression strength, shear strength, nail holding power of wood-plastic composite products. The computerized wood-plastic composite products universal testing machine adopts closed loop control system, with wide range of loading speed from 0.01mm/min to 500mm/min and force measuring range from 0.4% to 100% of full capacity. During test, test force, displacement, test time, test curves can be displayed in real time. After test, software auto calculate and save test results. It also allows client to self add test method and test steps.
