Applies to iron (3) sulfate solution of various iron and/or acid contents used for treatment of water intended for human consumption.

This European Standard is applicable to iron (III) sulfate solution of various iron and/or acid contents (see 3.2) used for treatment of water intended for human consumption. It describes the characteristics of iron (III) sulfate solution and specifies the requirements and the corresponding analytical methods for iron (III) sulfate solution (analytical methods are given in Annex B) and gives information on its use in water treatment. It also determines the rules relating to safe handling and use of iron (III) sulfate solution (see Annex E).
