EUROLAB laboratory provides testing and compliance services within the scope of EN 310 standard. The EN 310 standard specifies a method for determining the apparent modulus of elasticity in flat bending and flexural strength of wood-based panels with a nominal thickness greater than or equal to 3 mm. Structural design values will be determined according to methods according to EN 124.102.
The modulus of elasticity in bending and flexural strength is determined by applying a load to the center of a test piece supported at two points. The modulus of elasticity is calculated using the slope of the linear region of the load-deflection curve; the calculated value is the apparent modulus, not the actual modulus, because the test method involves shearing as well as bending. The bending strength of each test piece is calculated by determining the ratio of the bending moment M to the full section moment at the maximum load Fmax.
Sampling and cutting of test pieces will be done according to EN326-1. Both transverse and longitudinal test piece series are required. In the case of extruded panels, cellular panels, or panels of similar construction with gaps parallel to the length of the test piece, the width of the test piece should be at least twice the width of a single core element (i.e. two pipe diameters plus two body thicknesses) and the test pieces should be in a symmetrical shape. will have cross-sectional area.
Test pieces shall be conditioned to constant mass in an atmosphere of relative humidity (65±5%) and (20±2)°C. Constant mass is considered to have been reached when the results of two consecutive weighing operations performed at 24-hour intervals do not differ by more than 0,1% of the mass of the test piece.
Tests are carried out on two sets of test pieces according to the two directions of the board, namely the longitudinal and transverse directions. In each group, half of the test pieces are tested "top face up" and half "bottom face" up.
