ASTM D6045 Colorimeter Of Petroleum Products
KN-6045 Colorimeter for Petroleum Products conforms to the ASTM D6045 Standard Test Method for Color of Petroleum Products by the Automatic Tristimulus Method. Determination of the color of petroleum products is used mainly for manufacturing control purposes and is an important quality characteristic because color is readily observed by the user of the product. In some cases, the color may serve as an indication of the degree of refinement of the material. When the color range of a particular product is known, a variation outside the established range may indicate possible contamination with another product. However, color is not always a reliable guide to product quality and should not be used indiscriminately in product specifications.

ASTM D4530 Micro Carbon Residue Apparatus
The carbon residue value of the various petroleum materials serves as an approximation of the tendency of the material to form carbonaceous type deposits under degradation conditions similar to those used in the test method, and can be useful as a guide in manufacture of certain stocks. However, care needs to be exercised in interpreting the results
