Determination of the colour of is used mainly for manufacturing control purposes and is an important quality characteristic because colour is readily observed by the user of the product. When the colour range of a particular product is known, a variation outside the established range may indicate possible contamination. 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.  
Our commitment to quality and our accreditations demonstrates that we have rigorous quality systems in place that allow us to provide customers with the highest quality products possible, which are accepted globally. In addition, our Combined UKAS and ILAC-MRA Mark demonstrates that the accreditation we hold is recognized under the International Laboratory Accreditation Cooperation (ILAC) Mutual Recognition Arrangement, our certificates are accepted around the world.
