What is BS EN 890 - Water intended for human consumption - Iron (III) sulfate solution about?
BS EN 890 is a European standard that discusses rules relating to the safe handling and use of iron (III) sulfate in the treatment of water intended for human consumption.
BS EN 890 is applicable to iron (III) sulfate solution of various iron and/or acid contents used for the treatment of water intended for human consumption. BS EN 890 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. BS EN 890 also determines the rules relating to the safe handling and use of iron (III) sulfate solution.
Who is BS EN 890 - Water intended for human consumption - Iron (III) sulfate solution for?
BS EN 890 on water intended for human consumption - iron (III) sulfate solution is useful for:
- Water analysis laboratories
- Iron (III) sulfate solution manufacturers
- Packaged drinking water manufacturers
- Government agencies and research centres 
- Inspection personnel
- Water treatment plants
Why should you use BS EN 890 - Water intended for human consumption - Iron (III) sulfate solution?
Too much use of iron (III) sulfate solution in water treatment can cause nausea, severe stomach pain, bloody diarrhea, coughing up blood or vomit that looks like coffee grounds, shallow breathing, weak and rapid pulse, pale skin, blue lips, and seizure (convulsions). Therefore, BS EN 890 provides the rules relating to the safe handling and use of iron (III) sulfate solution.
BS EN 890 specifies the minimum purity criteria for iron (III) sulfate solution used for the treatment of water intended for human consumption. Depending on the raw material and the manufacturing process other impurities may be present and, if so, this shall be notified to the user and when necessary to relevant authorities.
BS EN 890 provides you with the characteristics of iron (III) sulfate solution and provides the requirements and the corresponding test methods for iron (III) sulfate solution. BS EN 890 gives information on its use in water treatment.
BS EN 890 provides you guidance on test methods that include sampling and analysis. BS EN 890 guides the labelling, transportation, and storage of the product so that the purity is not affected. BS EN 890 helps to avoid potential adverse effects on the quality of water intended for human consumption.
What is changed since the last update?
BS EN 890:2012 supersedes BS EN 890:2004 which is withdrawn.
BS EN 890:2012 includes some technical changes with respect to BS EN 890:2004.
These include:
- Change of the maximum allowed percentage of mass fraction of insoluble matter in the product from 0,3 % to 0,5 % (see Table 2)
- Update of the information of risk and safety labelling of the product to comply with the new regulations (see 6.2 and [2])
- Change of the method for determination of iron (III) sulfate to avoid the use of hazardous potassium dichromate (see B.1)
