DESCRIPTION

BS 5339:1976


This standard BS 5339:1976 Method of measurement of colour in Hazen units (platinum-cobalt scale) of liquid chemical products is classified in these ICS categories:
  • 71.040.50 Physicochemical methods of analysis

This International Standard specifies a method of measuring the colour in Hazen units of liquid chemical products.

It is applicable only to clear, slightly coloured liquids for which the colour characteristics are close to those of the reference platinum-cobalt scale. Such colour characteristics are generally describable as “brownish-yellow”.

This method is applicable whenever specified by an ISO Recommendation or International Standard relating to a given product.


Covers the two ranges 0 to 50 and 60 to 450 Hazen units. Applicable also to solutions and clear dispersions of, for example, plastics materials.
