1.1 This test method covers a procedure for testing of coarse
aggregates with a maximum size smaller than 37.5 mm ([11⁄2
in.] for resistance to degradation using the Los Angeles testing
machine (Note 1).
NOTE 1—A procedure for testing coarse aggregate larger than 19.0 mm
[3⁄4 in.] is covered in Test Method C535. Thus coarse aggregates with a
maximum size between 19 mm [3⁄4 in.] and 37.5 mm [11⁄2 in.] may be
tested by Test Method C535 or Test Method PS 4025.
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 are not necessarily exact equivalents; therefore, to
ensure conformance with the standard, each system shall be
used independently of the other, and values from the two
systems shall not be combined.
NOTE 2—Sieve size is identified by its standard designation in Specification
E11. The Alternative designation given in parentheses is for
information only and does not represent a different standard sieve size.
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, health, and environmental practices and determine
the applicability of regulatory limitations prior to use.
1.4 This 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.
