19、ope This European Standard is applicable to sodium hypochlorite used directly, or for the production of formulations for treating swimming pool water. It describes the characteristics of sodium hypochlorite and specifies the requirements and the corresponding test methods for sodium hypochlorite. It
20、 gives information on its use for treating swimming pool water and determines the rules relating to safe handling and use of sodium hypochlorite (see Annex B). 2 Normative reference The following referenced documents are indispensable for the application of this document. For dated references, only
21、the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 901, Chemicals used for the treatment of water intended for human consumption Sodium hypochlorite 3 Description The identification, the commercial form, the physica
22、l properties and the chemical properties are given in the relevant sub-clauses of EN 901. 4 Purity criteria 4.1 General This European Standard specifies the minimum purity requirements for sodium hypochlorite used for the treating swimming pool water. Limits are given for impurities commonly present
23、 in the product and depending on the raw material and the manufacturing process, other impurities may be present and if so, the user and when necessary, the relevant authorities shall be notified. NOTE Users of this product should check national regulations in order to clarify whether it is of appro
24、priate purity for treatment of water for swimming pools, taking into account water quality, required dosage, and contents of other impurities and additives used in the product not stated in the product standard. Limits have been given for impurities and trace elements where these are likely to be pr
25、esent in significant quantities from the current production process and raw materials. If the production process or raw materials lead to significant quantities of other impure by-products or additives being present, the user shall be notified. 4.2 Composition of commercial product Sodium hypochlori
26、te is available as a solution with a concentration up to 160 g of available chlorine per litre (equivalent to mass fraction of 13,5 %) at the time of delivery by the producer as calculated in accordance with the corresponding method given in EN 901. The concentration of sodium hypochlorite shall be
27、equal to or greater than the value specified by the manufacturer. 4.3 Impurities and main by-products The content of sodium chlorate (NaClO3) and sodium bromate (NaBrO3) for each type of product shall conform to the requirements specified in EN 901 The product shall be visibly free from deposits or

29、oduct shall conform to the requirements specified in EN 901. NOTE Cyanide (CN-) which does not exist in a strong oxidizing medium such as sodium hypochlorite, is not a relevant chemical parameter and as the raw materials used in the manufacturing process are free of pesticides and polycyclic aromati
30、c hydrocarbons, they are not relevant. 5 Test methods The methods for sampling and analysis are those specified in EN 901. 6 Labelling - Transportation - Storage 6.1 Means of delivery Sodium hypochlorite shall be delivered in: a) containers of polyethylene or polyvinyl chloride (PVC) with external g
31、lass fibre reinforcement (GFR); b) steel tank wagons lined with rubber or coated with suitable plastics. The containers shall be closed in such a manner so that no pressure can build up inside and no liquid can escape. The closure shall be protected from unintentional opening. To ensure the purity o
32、f the product is not affected, the means of delivery shall not have been previously used for any different product or it shall have been specially cleaned and prepared before use. 6.2 Risk and safety labelling according to the EU Directives 1) The following labelling requirements shall apply to sodi
33、um hypochlorite at the date of the publication of this European Standard. Symbols and indications of danger: C: Corrosive; Nature of special risks attributed to dangerous substances: R 31: Contact with acids liberates toxic gas; R 34: Causes burns. Safety advice concerning dangerous substances: S 2:
34、 Keep out of the reach of children; S 26: In case of contact with eyes, rinse immediately with water and seek medical advice. 1) See 1.

35、ntact with skin, wash immediately with plenty of water. S 37: Wear suitable gloves. S 45: In case of accident or if you feel unwell, seek medical advice immediately (show the label where possible). NOTE Annex I of the Directive 67/548/EEC on Classification, packaging and labelling of dangerous subst
36、ances and its amendments and adaptations in the European Union contains a list of substances classified by the EU. Substances not in this Annex I should be classified on the basis of their intrinsic properties according to the criteria in the Directive by the person responsible for the marketing of
37、the substance. 6.3 Transportation regulations and labelling Sodium hypochlorite is listed as UN Number 2) 1791. RID 3) ADR 4) : class 8, classification code C9; packing group III. IMDG 5) : class 8. IATA 6): class 8. 6.4 Marking The marking shall include the following: name “sodium hypochlorite“, tr
38、ade name and type; net mass; name and address of supplier and/or manufacturer; statement “this product conforms to EN 15077“. 6.5 Storage 6.5.1 General Sodium hypochlorite shall be protected against light, particularly direct sunlight. It shall be stored in cool rooms in containers made from metal w
39、ith internal coating or suitable plastics materials. In order to protect metal containers from corrosion, they shall be either rubber-lined or plastic-coated. NOTE Suitable venting should be used to prevent any pressure build-up in the containers. 2) United Nations Number. 3) Regulations concerning

The solution gradually decomposes resulting in the reduction of the concentration of the av
42、ailable (active) chlorine and resulting in increased level of chlorates, e.g. 1 g/l of (active) chlorine per day under a storage temperature of 20 C. 6.5.3 Storage incompatibilities Contact with acids or acidic salts leads to the formation of chlorine. In the presence of a high concentration of ammo
43、nia, ammonium salts and derivatives, and isocyanurate derivatives, vigorous reaction occurs with the formation of highly explosive nitrogen trichloride.

44、 9 Annex A (informative) General information on sodium hypochlorite A.1 Origin A.1.1 Raw materials Sodium hypochlorite is manufactured from chlorine (Cl2) and sodium hydroxide (NaOH). A.1.2 Manufacturing process Sodium hypochlorite is produced by reacting gaseous chlorine with a solution of sodium h
45、ydroxide. A.2 Use A.2.1 Function Sodium hypochlorite is used for disinfecting swimming pool water. A.2.2 Form in which it is used The product is used as delivered or diluted if necessary, depending on the required dose and size of pool. A.2.3 Treatment dose The treatment dose depends on the composit
46、ion of the water. The dose should be controlled to achieve the minimum free residual concentration that gives satisfactory disinfection. A.2.4 Means of application It is applied using a positive-displacement metering-pump. A.2.5 Secondary effects The secondary effects include the following: slight i
47、ncrease in pH; slight increase in the chloride content; chlorination of organic compounds leading to formation of halogenated by-products (e.g. trihalomethanes); localized precipitation of carbonate at the injection point. A.2.6 Removal of excess product The most practical method is the use of a red
48、ucing agent such as an aqueous solution of a sulphite compound. Other methods can use activated carbon or hydrogen peroxide.
