Limits are given for impurities commonly present in the produ
42、ct. 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 necessary to relevant authorities. Users of this product should check the national regulations in order to clarify whether it is of appropriate puri
43、ty for treatment of water intended for human consumption, taking into account raw water quality, required dosage, contents of other impurities and additives used in the product not stated in the product standard. 3)100 kPa = 1 bar BS EN 13176:2015EN 13176:2015 (E) 10 Limits have been given for impur
44、ities 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(s) to significant quantities of impurities, by-products or additives being present, this shall be notif
45、ied to the user. 4.2 Composition of commercial product The product shall contain a mass fraction of at least 95 % synthetic ethanol. The commercial product may contain up to a mass fraction of 5 % water. 4.3 Impurities and main by-products The acetaldehyde content shall not exceed 100 mg/kg of pure
46、ethanol. 4.4 Chemical parameters NOTE For the purpose of this European Standard, “chemical parameters” are those defined in the EU Directive 98/83/EC of 3 November 1998 (see 1).
