DIN EN 899:2009-07 EN 899:2009 (E) 8 3.4 Chemical properties Concentrated sulfuric acid reacts violently: with bases or with water (exothermic reaction); with reduci
39、ng agents due to oxidizing properties; with combustible materials due to oxidizing and dehydrating properties. The concentrated acid is a strong oxidizing agent and can cause ignition in contact with organic materials. Sulfuric acid (of sulfuric acid content less than a mass fraction of 70 % attacks
40、 most common metals, 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
41、 the minimum purity requirements for sulfuric acid 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 no
42、tified to the user and, 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, contents of othe
43、r impurities and additives used in the products 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 ma
44、terials lead to significant quantities of impurities, by-products or additives being present, this shall be notified to the user. 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 sulfuri
45、c acid 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. DIN EN 899:2009-0
