DIN EN 15078:2013-08 EN 15078:2013 (E) 5 1 Scope This European Standard is applicable to sulfuric acid used directly or for the production of formulations for the treatment of water for swimming pools. It describes the characteristics and specifies the requirements and the corresponding test

24、 methods for sulfuric acid. It gives information on its use for treatment of water for swimming pools. It also determines the rules relating to safe handling and use (see Annex B). 2 Normative reference The following documents, in whole or in part, are normatively referenced in this document and are

34、dising properties; with combustible materials due to oxidising and dehydrating properties. The concentrated acid is a strong oxidising agent and can cause ignition in contact with organic materials. Sulfuric acid (of sulfuric acid content less than a mass fraction of 70 %) attacks most common metals

35、, e.g. iron, zinc, liberating the flammable gas hydrogen. WARNING Mixing with water produces a marked temperature rise. Therefore ALWAYS ADD THE ACID TO THE WATER (NEVER THE REVERSE), slowly and agitating continuously. 4 Purity criteria 4.1 General This European Standard specifies the minimum purity

36、 requirements for sulfuric acid used for the treatment of water for swimming pools. 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, when n

37、ecessary, to the relevant authorities. Users of this product should check the national regulations in order to clarify whether it is of appropriate purity for treatment of water for swimming pools, taking into account raw water quality, contents of other impurities and additives used in the products

38、 not stated in the product standard. Limits have been given for impurities and chemicals 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 impur

39、ities, by-products or additives being present, this shall be notified to the user. DIN EN 15078:2013-08 EN 15078:2013 (E) 8 4.2 Composition of commercial product The usual commercial concentrations of sulfuric acid available have a mass fraction of 96 % or 98 %. Other concentrations of sulfuric acid

40、 between a mass fraction of 25 % and 80 % are also available. If sold as concentrated acid, the mass fraction of sulfuric acid shall be in the range of 92 % to 98 %. The concentration of sulfuric acid shall be within a mass fraction of 1 % of the manufacturers declared value. 4.3 Chemical parameters
