Significance and Use
5.1 The kerosene retention value is an indication of the degree of fiberization and of the absorptivity of a given grade of asbestos.
5.2 Since the retention of the fibrous fractions is much greater than that of the non-fibrous fractions, this test method may be used to compare the fibrous content of otherwise similar grades of asbestos.
Scope
1.1 This test method covers the determination of the kerosene retention capacity of asbestos fiber by filtering after mixing and measuring the volume of liquid retained by difference.
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.
