IP 17: Determination of colour — Lovibond® tintometer® method

Overview:

Scope

This document specifies a method of test for determining the colour of dyed and undyed petroleum products except those containing residues from crude petroleum processing. Solid or semi-solid products, such as petrolatum and wax, are tested in the molten state. This procedure is based on a trichromatic scale using a series of red, yellow and blue glasses to measure the depth of colour in Lovibond units.

NOTE - This procedure was identified as procedure A in previous versions of this standard, which described two procedures for the determination of colour.
