ASTM C1352 covers the procedure for determining the flexural modulus of elasticity of stone by using a simple beam with quarter-point loading. Stone tests may be made with load applied perpendicular to the bedding plane or rift and with load applied parallel to the bedding plane or rift. ASTM C1352 is useful for providing engineering values for stress and deflection analysis of stone panels. ASTM C1352 also useful in indicating the differences in flexural modulus of elasticity between various dimension stones and stones of the same type in different loading directions (parallel and perpendicular to rift or bedding planes).
