適用范圍：This European Standard 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 waterintended for human consumption and industrial use, 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 choice 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 apply 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 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 consumption, 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 enduser. For this purpose, reference should be made to the relevant national standards transposing EN standards when available, dealing with the influence of materials on water quality.
