Liquid chemical products -- Measurement of colour in Hazen units (platinum-cobalt scale)
Applicable only to clear, slightly coloured liquids. Such colour characteristics are described as brownish-yellow.
The principle is based on a visual comparison of the colour of a sample with that of colour standards. The results are expressed in terms of the platinum-cobalt scale.
For routine control purposes, a comparator, colorimeter or spectrophotometer may be used, if the values so obtained are identical with those obtained by visual comparison.
