Limits are given
29、 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 when necessary to the relevant authorities. Users of the product should check national regulations in order
30、to clarify whether it is of appropriate purity for treatment of swimming pool water, taking into account water quality, required dosage, and contents of other impurities and additives used in the product not stated in the product European Standard. Limits have been given for impurities and chemical
31、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 other impurities, by-products or additives being present, this shall be notified to the user.

46、rom natural carbon dioxide chiefly in the components of residual gases. A.1.2 Manufacturing process Carbon dioxide is condensed gradually in one or more steps up to the corresponding liquefy pressure, than cleaned, dried up, if needed filtered and subsequently liquefied in large scaled refrigerators
47、, after that stored in pressure vessels (tanks). A.2 Use A.2.1 Function The product is used for adjustment of pH value of pool water. A.2.2 Form in which it is used The product is used in gaseous form. A.2.3 Treatment dose The treatment dose is variable depending on the composition of swimming pool
48、water. For example, to increase the hydrogen carbonate content of the water, expressed as calcium carbonate, by 10 mg/l a dose of 4,4 mg CO2/l would be required.
