EN 901 (sodium hypochlorite) for those impurities commonly present in the product and the chemical parameters. Consideration has also been given to the requirements of EN 973 (sodium chloride) for regeneration of ion exchangers. 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 1 Users of this product should check the national regulations in order to clarify whether it is of appropriate purity for the treatment of water intended for human consumption, taking into account raw water quality, required dosage, contents of other impurities and additives used in the product and not stated in this product standard. NOTE 2 Using the sodium hypochlorite standard to define limits produces discrepancies with EN 973 regarding sodium chloride for the regeneration of ion exchange water softeners. This should not be taken to imply any real difference between the chemical purity between salt types meeting either specification. Limits have been given for impurities and chemical parameters where these 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 impurities, by-products or additives being present, this shall be notified to the user. SIST EN 14805:2009
