ASTM D 1918 : 1995 : R2004 : EDT 1

CONTAINED IN VOL. 04.05, 2009 Determines asbestos content of untreated chrysotile asbestos textile materials, usually blends of asbestos and organic fibers.

1.1 This test method covers the determination of the asbestos content of untreated chrysotile asbestos textile materials which are usually blends of asbestos and organic fibers. This test method is also applicable to treated asbestos textile materials provided the treatment can be completely removed prior to testing.

1.2 This test method is limited to those asbestos textile materials in which asbestos is the only inorganic fiber present, or in which any other inorganic fiber or wire used as reinforcement can be removed prior to testing.

1.3 If carbonates are present, a correction is made for the loss on ignition in the calculation for asbestos content.

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."

1.6 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 specific safety hazard, see 1.5.
