More D The presence or absence of color in such material is an indication of the degree of refinement to which the solvent has been subjected or of the cleanliness of the shipping or storage container in which it is handled, or both. This was accomplished in with the adoption of Test Method D using the platinum-cobalt scale. Hazen in the American Chemical Journal5 in which he assigned the number 5 parts per ten thousand to his platinum-cobalt stock solution. Subsequently, in their first edition of Standard Methods for the Examination of Water, the American Public Health Association, using exactly the same concentration of reagents, assigned the color designation parts per million which is the same ratio. The parts per million nomenclature is not used since color is not referred directly to a weight relationship.

The petroleum industry uses the Saybolt colorimeter Test Method D for measuring and defining the color of hydrocarbon solvents; however, this system of color measurement is not commonly employed outside of the petroleum industry.

Historical Version s — view previous versions of standard. The parts per million nomenclature is not used since color is not referred directly to a weight relationship.

The property of color of a solvent varies in importance with the application for which it is intended, the amount of color that can be tolerated being dependent on the color characteristics of the material in which ashm is used.

Because of the differences in the spectral characteristics of the several color systems being compared and the subjective manner in which the measurements are made, exact equivalencies are difficult to obtain. No other units of measurement are included in this standard.

This was accomplished in with the adoption of Test Method D using the platinum-cobalt scale. 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. Related Posts
