適用范圍：This European Standard defines the internal and/or external polyamide powder coatings applied by dipping in a fluidised bed or by spraying, or by roto-coating. These coatings are intended for the protection the inner and outer surfaces of steel tubes and their fittings (components) used as component parts of pipelines. This standard may also be applied for accessories, such as valves, pumps, screens, etc. This type of coating is used for the protection of buried, submerged or above ground pipelines conveying fluids at working temperatures between 0 ℃ and + 60 ℃. Other working service temperatures can be used after agreement between the purchaser and the coater. The coatings covered by this standard are applicable to longitudinally or spirally welded steel tubes and to seamless steel tubes and their fittings components used for the construction of pipelines conveying liquids. The internal coating of tubes to be used for the transportation of water intended for human consumption should not affect the quality of that water to such an extent that it fails to comply with the requirements of the EU and EFTA regulations. For this purpose, reference should be made to the relevant national regulations and standards, transposing EN standards when available, dealing with the influence of materials on water quality and to the requirements for coatings. NOTE A European Acceptance Scheme (EAS) is in course of development in relation to the CPD and the DWD. Its requirements will be introduced in this standard when completed.
