Significance and Use

The equipment required and the technique followed are both simple and undemanding.
1.1 This test method covers the procedure for determining the fines content of asbestos fibers by washing with water on a specified sieve.
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.
