Additional information

1. 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 E308.
