18、 10339:2007) has been prepared by Technical Committee ECISS/TC 29 “Steel tubes and fittings for steel tubes”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest

19、by August 2007, and conflicting national standards shall be withdrawn at the latest by August 2007. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Cz

EN 10339:2007 (E) 4 1 Scope This European Stand

21、ard specifies the requirements for the application of liquid applied epoxy internal linings, for the corrosion protection of steel tubes. This type of lining is generally used in the transport and distribution, under pressure or by gravity, of water intended for human consumption and industrial use,

22、 sea water, waste water and also in fire water. The temperature of the water transported generally does not exceed 50 C. The choice of the lining and its limits of use depend on the type of product used, the pipe laying conditions, the temperature and the chemical composition of the fluid. The choic

23、e of the product for the medium to be transported and its qualification are not part of this European Standard. The lining consists normally of one layer of liquid product, applied by spray airless technique after surface preparation. All or some of the requirements of this European Standard can app

24、ly to the internal linings of fittings, if agreed by the purchaser and the coater. The lining in this European Standard can be applied to longitudinally or spirally welded tubes and to seamless steel tubes used for the construction of pipelines for conveying liquids. These tubes are not intended to

25、be bent after the epoxy lining has been applied. This European Standard does not cover in-situ applied or rehabilitation linings. The constituent materials of epoxy linings, when used under the conditions for which they are designed, in permanent or temporary contact with water intended for human co

26、nsumption, should not change the quality of that water to such an extent that it fails to comply with the requirements of European regulations at the end user. For this purpose, reference should be made to the relevant national standards transposing EN standards when available, dealing with the infl

27、uence of materials on water quality. 2 Normative references The following referenced documents are indispensable for the application of this document.

35、ing symbol applies. Rzthe average roughness from five successive evaluation areas defined according to EN ISO 4287, expressed in microns (m) 5 Lining materials 5.1 General The lining material is generally composed of a base (epoxy resin) and a curing agent. A primer may be used when recommended by t

36、he product manufacturer. The base (epoxy resin) and curing agent should have different colours allowing the verification of the correct mixing by checking the uniformity of the colour of the mixed product. This European Standard calls for the use of substances and/or procedures that may be injurious

37、 to health if precautions are not taken. It refers only to technical suitability and in no way absolves the user from statutory obligations relating to health and safety at any stage. 5.2 Technical specification The technical specification drawn up by the product manufacturer shall contain as a mini

38、mum the information detailed in Table 1. Where testing standards are mentioned in Table 1, the data supplied by the product EN 10339:2007 (E) 6 manufacturer shall be according to these standards. Otherwise, test methods shall be given for any test detailed in Table 1. Tests shall be done to be consi

39、stent with the product manufacturers recommendations for application. Infrared scan of the product components shall be made available on request to the coater. Other data or tests can be agreed between the parties at the time of enquiry and/or order. If test certificates are required, they shall at

40、least contain the data mentioned in Table 1.
