ASTM C170/C170M-09
(Test Method)Standard Test Method for Compressive Strength of Dimension Stone
Standard Test Method for Compressive Strength of Dimension Stone
SIGNIFICANCE AND USE
This test method is useful in indicating the differences in compressive strength between the various dimension stones. This test method also provides one element in comparing stones of the same type.
SCOPE
1.1 This test method covers the sampling, preparation of specimens, and determination of the compressive strength of dimension stone.
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4. Significance and Use
4.1 This test method is useful in indicating the differences in compressive strength between the various dimension stones. This
test method also provides one element in comparing stones of the same type.
5. Apparatus
5.1 Any testing machine conforming to Practices E 4 and to the speed of testing requirements prescribed in Section 9 of this
test method may be used.
5.2 In vertical testing machines, the spherical bearing block shall be suspended from the upper head of the machine in such a
manner that the contact plate remains in a central position (spherical surfaces in full contact) when not loaded. The spherical
surfaces shall be well lubricated, and the center of curvature shall lie in the surface of contact with the specimen.
6. Sampling
6.1 The sample shall be selected to represent a true average of the type or grade of stone under consideration and shall be of
the quality supplied to the market in finished form under the type designation to be tested. The sample may be selected by the
purchaser or his authorized representative from quarried stone or taken from the natural ledge and shall be of adequate size to
permit the preparation of the desired number of test specimens. When perceptible variations occur, the purchaser may select as
many samples as are necessary for determining the variation in compressive strength.
