This standard specifies the test method for the determination of the stiffness of impregnated skeleton materials by the three-point bending method using the principle of two-point support bending stiffness. This standard is applicable to the determination of the stiffness of dipped cord fabrics, dipped canvas, dipped cords and other dipped skeleton materials made of fibers.
