ASTM D 3879 : 1991 : R2004 : EDT 1

1.1 This test method describes the procedure for taking a composite sample or a master composite sample (at the mine, at the factory, or from a consignment) from a lot of commercial milled amphibole fibers, conditioning the sample, and reducing it in quantity so as to provide a series of relatively small test specimens of loose asbestos fiber, each of which may be regarded as representative of the lot. (See for sampling strategy.)

1.2 This test method is suitable for taking test specimens of amphibole asbestos for the following test methods: C 1119, C 1120, C 1121, C 1122, C 1123, C 1124, C 1125, C 1162, D 1118, D 2589, D 2752, D 2947, D 2985, D 2987, D 3639, D 3752, and D 3880.

1.3 For sampling chrysotile asbestos, use Method D 2590.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 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."

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 for a specific hazard warning.
