19、uropean 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 methods for sulfuric acid. It gives information on its use for
20、 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 referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated ref
21、erences, the latest edition of the referenced document (including any amendments) applies. EN 899, Chemicals used for treatment of water intended for human consumption - Sulfuric acid 3 Description The identification, the commercial form, the physical properties and the chemical properties are given
22、 in the relevant subclauses of EN 899. 4 Purity criteria 4.1 General This European Standard specifies the minimum purity 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 a
23、nd 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 Users of this product should check the national regulations in order to clarify whether it is of appropriate purity for treatment of water for
24、swimming pools, taking into account water quality, required dosage, contents of other impurities and additives used in the products not stated in this product standard. Limits have been given for impurities and trace elements where these are likely to be present in significant quantities from the cu
25、rrent 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. 4.2 Composition of commercial product Sulfuric acid sold as concentrated acid has a mass fr
26、action between 96 % and 98 %. Other concentrations of sulfuric acid are also commercially available.

42、006 EN 15078:2006 (E) 9 Annex A (informative) General information on sulfuric acid A.1 Origin A.1.1 Raw materials Sulfuric acid is manufactured from sulfur dioxide gas, which is produced, for example, by burning elemental sulfur or roasting of metal sulfide ores. A.1.2 Manufacturing process Sulfuric
43、 acid is produced by the catalytic oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3), absorption of sulfur trioxide in sulfuric acid and dilution with water to the required grade. A.2 Use A.2.1 Function In the treatment of water for swimming pools, sulfuric acid is used to adjust the pH val
44、ue. A.2.2 Form in which it is used Sulfuric acid used for treatment of swimming pool water typically has a content of 30 % mass fraction to 45 % mass fraction and is used as delivered. A.2.3 Treatment dose The treatment dose depends on the chemical characteristic of the swimming pool water to be tre
45、ated, e.g. pH value, sulfate content, and on the type of the water treatment. A.2.4 Means of application The treatment dose is usually applied using a metering pump. A.2.5 Secondary effects Temperature rise at the injection point. Corrosion of equipment and piping can occur, if sulfuric acid is adde
46、d in excess. A.2.6 Removal of excess product The excess product is removed by neutralization.

47、1 Rules for safe handling and use The supplier shall provide current safety instructions. The place where sulfuric acid is stored or handled shall be made of acid-proof material inside a bunded area, to catch any spillage. B.2 Emergency procedures B.2.1 First aid Immediately take off all contaminate
48、d clothing. In case of contact with skin, wash immediately with plenty of water. In case of contact with eyes : if even small amounts of sulfuric acid enter the eyes, immediately rinse with water for at least 15 min, with the eye lids held open. Immediately consult a doctor. B.2.2 Spillage Dilute sm
49、all spillages with plenty of water, neutralize with lime or sodium carbonate. Small quantities shall be rinsed off with plenty of water. Never use flammable material to absorb acid spills. Large spillage: the acid shall be contained (see B.1), pumped to an appropriate container or tank. Seek expert assistance. B.2.3 Fire Sulfuric acid is not combustible. Extinguishing media: no restriction in fire situations, however concentrated sulfuric acid reacts violently with water. Licensed Copy: London South Bank University, South B
