ISO 7887:1994 Water quality - Examination and determination of colour

This Standard cancels and replaces the first edition (1985).

It specifies three methods for the examination of colour:

a method for the examination of apparent colour by visually observing a water sample in a bottle;
a method for the determination of the true colour of a water sample using optical apparatus;
a method for the determination of the colour by visual comparison with hexachloroplatinate standard solutions.

Under certain circumstances, strongly coloured water samples need to be diluted before examination or determination.
