32、 for calcium magnesium oxide used for the treatment of water intended for human consumption. Limits are given for impurities commonly present in the product. 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
33、 when necessary to the relevant authorities. NOTE Users of this product should check the national regulations in order to clarify whether it is of appropriate purity for treatment of water intended for human consumption, taking into account raw water quality, required dosage, contents of other impur
34、ities and additives used in the product not stated in this product standard. Limits have been given for impurities and toxic substances where these are likely to be present in significant quantities from the current production process and raw materials. If a change in the production process or raw m
35、aterials leads to significant quantities of other impurities or by-products being present, this shall be notified to the user. 2) European Inventory of Existing Commercial Chemical Substances.
