ASTM C-97 - Water Absorption Test: Recommended for all dimension stone used for
exterior installation and for interior flooring and base course. Maximum absorption rate by
weight for granite is 0.4%.
ASTM C-170 - Compressive Strength Test: Adequate for design of simple construction, but
not sufficient for thin veneer design of high-rise construction. The minimum requirement for
compressive strength of granite is 19,000.
ASTM C-99 – Modulus of Rupture Test: Useful in the design of panel sizes, thickness, and
surface finish and is useful to design limitations of anchoring. The minimum requirement for
flexural strength of dimensional granite is 1,500 psi and 10.34 Mpa.
ASTM C-241 – Abrasion Resistance Test: Determines the abrasion resistance of all types of
natural stone for floors, steps, and similar uses where wear is caused by the abrasion of foot
traffic. The minimum abrasion resistance of granite is 25 Ha.
ASTM C-880 – Flexural Strength Test: Provides information for the design of panel sizes,
thickness, surface finish, and anchoring limitations. The minimum requirement for granite
dimension stone is 1,200 psi (8.27 Mpa).
