(Test Method)Standard Test Method for Modulus of Rupture of Dimension Stone
Standard Test Method for Modulus of Rupture of Dimension Stone
SIGNIFICANCE AND USE
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 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.
