Significance and Use | ||||||||||||||||||||
5.1 This test method can be used to estimate the speed of drainage and the rate of production of products from the fiber evaluated, in industrial applications. It may be applied to single grades of fiber, or to fiber blends, together with the same binder system and process water used in the process under evaluation. |

1. Scope | ||||||||||||||||||||
1.1 This test method describes a laboratory procedure for the evaluation of asbestos fiber by measuring the rate of drainage under suction, of an asbestos-cement mixture. 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.”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. See Note 1 and 1.3 for specific hazard warnings. |
