ASTM C99 – Standard Test Method for Modulus of Rupture of Dimension Stone
Description:
Significance and Use
4.1 This test method is useful in indicating the differences in modulus of rupture 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 determination of the modulus of rupture of all types of dimension stone except slate.
1.2 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.
