ISO 2049 - ASTM Color
We perform testing by ISO 2049 to visually measure the color of petroleum products such as lubricating oils, heating oils, diesel fuel oils, and waxes. Determination of the color of petroleum products is used mainly for manufacturing control purposes and is an important quality characteristic, since 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.
We also perform color analysis by ASTM D1500, ASTM D156, ASTM D6045, ASTM D848, and IP 196.These different test methods use different instruments or procedures or are used for certain sample types. Click on the test method number to learn more about each test.
