Standard Test Method for Wet Volume of Asbestos (Withdrawn 2021)

Significance and Use

5.1 Wet volume gives an indication of the degree of loftiness and openness of asbestos fiber.


1.1 This test method covers the appraisal of asbestos fiber groups 4 to 7 (see Note 1) in terms of their occupied volumes when immersed in water.

Note 1: Quebec Standard designation of chrysotile asbestos grades as determined by Test Method D3639/D3639M.

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.

1.3 Warning—Breathing of asbestos dust is hazardous. Asbestos and asbestos products present demonstrated health risks for users and for those with whom they come into contact. In addition to other precautions, when working with asbestos-cement products, minimize the dust that results. For information on the safe use of chrysoltile asbestos, refer to “Safe Use of Chrysotile Asbestos: A Manual on Preventive and Control Measures.”2

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. For a specific hazard warning, see 1.3.
