19、nts (iron (III) chloride, iron (III) chloride sulfate and iron (III) sulfate liquid) used directly or for the production of formulations for treatment of water for swimming pools. It describes the characteristics of iron based coagulants and specifies the requirements and the corresponding test meth

20、ods for iron based coagulants. It gives information on their use in swimming pool water treatment. General information on iron based coagulants is given in Annex A. It also determines the rules relating to safe handling and use (see Annex B). 2 Normative references The following referenced documents

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. NOTE Users of these products should check the national regulations in order to clarify whether t

25、hey are of appropriate purity for treatment of water for swimming pools, taking into account water quality, required dosage, contents of other impurities and additives used in these products not stated in these product standards. Limits have been given for impurities and chemical parameters where th

26、ese are likely to be present in significant quantities from the current production process and raw materials. If the production process or raw materials lead to significant quantities of other impurities by-products or additives being present, this shall be notified to the user. 4.2 Composition of c
