(Test Method)Standard Test Method for Clay Lumps and Friable Particles in Aggregates
Standard Test Method for Clay Lumps and Friable Particles in Aggregates
SIGNIFICANCE AND USE
4.1 This test method is of primary significance in determining the acceptability of aggregate with respect to the requirements of Specification C33/C33M.
SCOPE
1.1 This test method covers the approximate determination of clay lumps and friable particles in aggregates.
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.
Note 1: Sieve sizes openings are identified by their Specification E11 designation with their alternative Specification E11 designation given in parentheses for information only.
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.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
