1 Scope
This document is applicable to iron-based coagulants used for treatment of water intended for human
consumption. It specifies analytical methods to be used for products described in EN 888 (Iron (III)
chloride), EN 889 (Iron (II) sulfate), EN 890 (Iron (II) sulfate, solution), EN 891 (Iron (III) chloride
sulfate) and EN 14664 (Iron (III) sulfate, solid).
