The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of color, whiteness, and yellowness of asbestos by means of a photoelectric reflectometer.
1.2 The test method is applicable to all grades and varieties of homogeneous milled asbestos.
1.3 This test method may be applied to samples that are not dry or homogeneous, or that contain impurities or adulterants. However, in such cases, results may not be comparable with those obtained on clean dry samples.
1.4 To obtain similar results from spectrophotometers, see Test Method E 308.
1.5 The values stated in SI (metric) units are to be regarded as standard. The inch-pound (customary) units are for information only.
1.6 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 chrysotile asbestos, refer to "Safe Use of Chrysotile: A Manual of 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.
Significance and Use
The color of asbestos is of commercial significance when it is to be incorporated into products, the color of which is affected by the color of the asbestos, and for which color specifications must be met.
Whiteness is required of asbestos for use in white or pale-colored products.
Yellowness is significant in asbestos for use in pastel-colored products where discolored asbestos may prevent attainment of certain shades and hues detector.
