Limits are given for impurities commonly present in the product. Depending on the r

37、aw material and the manufacturing process, other impurities may be present and, if so, the user, and when necessary the relevant authorities, shall be notified. Users of the product should check the national regulations to clarify whether it is of appropriate purity for treating water for swimming p

38、ools, taking into account raw water quality, required dosage, contents of other impurities and additives used in the product that are not stated in this product standard. Limits have been given for impurities and chemical parameters where these are likely to be present in significant quantities from

39、 the current production process and raw materials. If the production process or raw materials lead to the presence of significant amounts of impurities, by-products or additives, the user shall be notified. 4.2 Composition of commercial product Sodium hypochlorite is available only in solutions with

40、 concentrations up to 18 % active chlorine at the time of delivery by the producer. Common concentrated products contain a minimum of 12 % active chlorine. Diluted solutions are also available. The concentration of sodium hypochlorite shall be equal to or greater than the value specified by the manu

41、facturer. 4.3 Impurities and main by-products The product contains sodium chloride (NaCl) in equimolar amounts at minimum, and a small portion of sodium hydroxide (NaOH) which keeps the product alkaline. Therefore, a small amount of sodium carbonate (Na2CO3) can also be present. The sodium chlorate

42、(NaClO3) content shall not exceed a mass fraction of 5,4 % of available chlorine at the time of delivery by the producer. The product shall be visibly free from deposits or suspended matter. NOTE Sodium chlorate is a by-product of the manufacturing process and can be formed during storage (see 6.5.1

43、). 4.4 Chemical parameters The product shall conform to the requirements specified in Table 1.
