Cancels and replaces the first edition (1985). 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.
