This European Standard specifies the determination of mercury in two parts which use either tin(II)chloride or sodium tetrahydroborate as reducing agent. The methods described in clauses 4 and 5 are suitable for the determination of mercury in water, for example in ground, surface and waste waters, in the concentration range from 0,01 microgram/l to 1 microgram/l. Higher concentrations may be determined if the water sample is diluted.
