Description / Abstract:
This International Standard specifies a method for estimating
the colour of optically clear, yellow/brownish coloured liquid
products by means of the Gardner colour scale using
colour-measuring instruments. The method uses the Gardner colour
scale described in Annex A.
It is applicable to drying oils, varnishes and solutions of
fatty acids, polymerized fatty acids, resins, tall oil, tall oil
fatty acids, rosin and related products. The results might be
invalid if other products are tested.
The method described provides a more precise way of measuring
Gardner colour than a visual sample comparison using human eyes. It
is applicable to products having colours from Gardner 1 to Gardner
18. The Gardner scale is not applicable to products with colours
darker than 18. For products with colours lighter than Gardner 1
the method specified in ISO 6271 applies.
