This European Standard specifies the requirements, sampling, test methods and conditions of delivery for seamless round copper tubes. It is applicable to tubes having an outside diameterr from 6 mm up to and including 267 mm for: distributing networks for hot water and cold water; hot water heating systems, including panel heating systems (under-floor, wall, overhead); domestic gas and liquid fuel distribution; waste water sanitation. It is also applicable to seamless round copper tubes intended to be pre-insulated before use for any of the above purposes. In comparison with the first edition of EN 1057:1996, the following significant technical changes were made: harmonization of the standard to the Construction Product Directive (CPD) and to the Pressure Equipment Directive (PED); introduction of two new definitions: "permanently marked" and "durably marked"; updating of the definitions regarding soldering, brazing, fusion welding, braze welding and mean diameter; introduction of five new items in Clause 5 "Ordering information" regarding options on tests and documents; due to the process of harmonization to the CPD, introduction of three new characteristics in Clause 6 "Material characteristics" inherent to copper material which are not to be tested; modification of Table 3 "Standardized dimensions"; simplification of Table 6 "Quantitative and qualitative specification for carbon residues": Suppression of the residual and potential carbon and application of the thresholds to the total carbon; text in Clause 8 "Evaluation of conformity" added due to the process of harmonization to the CPD; for permanent and durable markings, specification of their applicability in 12.1 "Marking"; modification of the table in Annex A, introduction of new diameters and wall thicknesses; due to the process of harmonization to the CPD and PED introduction of Annexes ZA and ZB.
