→Used for determining the flexural strength and the apparent flexural modulus of elasticity of rigid cellular plastics.
→Used for assessing the behaviour of a bar of rigid cellular plastic under the action of three-point bending, to determine either the load for a specified deformation or the load at break.
→Used for determine the compressive strength and corresponding relative deformation or the compressive stress at 10% relative deformation and when desired, the compressive modulus of rigid cellular plastics.
→Used for determine the tensile strength of rigid cellular plastics.
→Place a test specimen symmetrically upon the support edges and apply an increasing force perpendicular to the longitudinal axis of the specimen by moving the loading edge at a constant speed of:
(20±1)mm/min for the determination of the apparent flexural modulus
either (20±1)mm/min or (100±10)mm/min for the determination of other flexural properties.
