ASTM C170/C170M-14
(Test Method)Standard Test Method for Compressive Strength of Dimension Stone
Standard Test Method for Compressive Strength of Dimension Stone
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.
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.
