Significance and Use
The test method is used to estimate qualitatively the durability of weak rocks in the service environment.(1-7)3 .
This test method is used to assign quantitative durability values to weak rocks. A primary example is the Franklin Rating System (1).
Note 1—The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D 3740
Scope
1.1 This test method covers the determination of the slake durability index of a shale or other similar rock after two drying and wetting cycles with abrasion.
1.2 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D 6026.
1.2.1 The method used to specify how data are collected, calculated, or recorded in this standard is not directly related to the accuracy to which the data can be applied in design or other uses, or both. How one applies the results obtained using this standard is beyond its scope.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
1.4 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.
