ASTM Colour of Petroleum Products (ASTM Colour Scale) test method covers the visual determination of the colour of a wide variety of petroleum products, such as lubricating oils, heating oils, diesel fuel oils, and petroleum waxes.

Determination of the colour of petroleum products is used mainly for manufacturing control purposes and is an important quality characteristic because colour is readily observed by the user of the product. In some cases, the colour may serve as an indication of the degree of refinement of the material. When the colour range of a particular product is known, a variation outside the established range may indicate possible contamination with another product. There are several other colour scales that can be used for the determination of colour, these include Gardner Colour, Platinum-Cobalt Colour and Saybolt Colour. We can supply colour reference standards for use in the colour scales listed.
