1.1 This test method covers the visual determination of the color of a wide variety of petroleum products, such as lubricating oils, heating oils, diesel fuel oils, and petroleum waxes. NOTE 1—Test Method D 156 is applicable to refined products that have an ASTM color lighter than 0.5.

ASTM Color of Petroleum Products (ASTM Color Scale)1 This standard is issued under the fixed designation D1500; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

ASTM D 1500 is a standard test method for ASTM color of petroleum products. It introduces ASTM color scale containing 16 ASTM color indices ranging from 0.5 for the lightest color to 8.0...

The distinct petroleum colors can be accurately measured and the refinement process controlled using the ASTM D 1500 color scale. The ASTM D 1500 color scale is also used for product and interface detection, and for product contamination monitoring.

The color of an oil can range from colorless, transparent, pale yellow, yellow, bright yellow, amber, brown, dark brown, hazy, turbid, opaque, milky, black, etc. A change in color usually indicates either a change in the chemistry of the oil or contamination of the oil.

Sometime referred to as the "mineral oil color value", the ASTM Colour Scale is widely used for the grading of petroleum products such as lubricating oils, heating oils and diesel fuel oils. Mineral oils are constantly checked for colour during processing in order to establish when they have been refined to the required grade.

This course is based on ASTM D1500 Standard Test Method for ASTM Color of Petroleum Products (ASTM Color Scale). This test method covers the visual determination of the color of a wide variety of petroleum products, such as lubricating oils, heating oils, diesel fuel oils, and petroleum waxes.

With a 3-section field of view, the sample and two adjacent standards on the ASTM Color Scale are viewed simultaneously, making it easier to achieve the optimum colour match. For rapid colour grading within predetermined colour limits, the glass

The ASTM D1500 Color scale is used for ranking certain petroleum products based on color. The products that D1500 is used to evaluate are usually lubricants, additives, and specific oils.
