METHODOLOGY FOR MEASURING THE SHEAR STRESS OF PLASTERBOARDS
Keywords:plasterboard, shear strength perpendicular to the plane of the board, EN 789, ASTM
AbstractPlasterboards have to meet many requirements for certification. The mechanical properties of itself plasterboard are one of them. The important mechanical property of the plasterboard is the shear strength perpendicular to the plane of the board. The European Standard refers to performing the relevant test for the procedure set out in the wood standard EN 789. But is this methodology for plasterboard the most suitable? This paper compares this recommended method with the alternative method according to the American Standard ASTM D5379 with indicating the results of a specific measurement.
