Standard Test Method for Color of Liquids Using Tristimulus Colorimetry

Importancia y uso:

4.1 The primary objective of Pt-Co color measurement, as defined in Test Method D8005, is to rate specific materials for yellowness. This yellowness is frequently the result of the undesirable tendency of liquid hydrocarbons to absorb blue light due to contamination in processing, storage, or shipping.

4.2 Clear liquids can be rated for light absorbing yellowish or brownish contaminants using scales that simulate the long-established visual-comparison method.
