Abstract This International Standard specifies three methods for the examination of colour. Section 2 specifies a method for the examination of apparent colour by visually observing a water sample in a bottle. This gives only preliminary information, for example for use in field work. Only the apparent colour can be reported. Section 3 specifies a method for the determination of the true colour of a water sample using optical apparatus and is applicable to raw and potable water and to industrial water of low colour. For interferences, see 3.3. Section 4 specifies a method for the determination of the colour by visual comparison with hexachloroplatinate standard solutions and may be applied to raw and drinking water. For interferences, see 4.2. Under certain circumstances, strongly coloured water samples need to be diluted before examination or determination. When stating the result, it is absolutely necessary to refer to the applied method.
