ASTM C142 – Standard Test Method for Clay Lumps and Friable Particles in Aggregates
Description:
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.
