24、10 (E) 4 Foreword This document (EN 1057:2006+A1:2010) has been prepared by Technical Committee CEN/TC 133 “Copper and copper alloys”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by en
25、dorsement, at the latest by August 2010, and conflicting national standards shall be withdrawn at the latest by August 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for iden
26、tifying any or all such patent rights. This document includes Amendment 1, approved by CEN on 2010-01-10. This document supersedes !EN 1057:2006“. The start and finish of text introduced or altered by amendment is indicated in the text by tags !“. Within its programme of work, Technical Committee CE
27、N/TC 133 requested CEN/TC 133/WG 3 “Copper tubes (installation and industrial)“ to prepare the revision of the following standard: EN 1057:1996, Copper and copper alloys Seamless, round copper tubes for water and gas in sanitary and heating applications This document has been prepared within the fra
28、mework of two mandates given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of the EU Construction Products Directive (CPD) 89/106/EEC and the EU Pressure Equipment Directive (PED) 97/23/EC. For relationship with EU Directives, see info
29、rmative Annexes ZA and ZB, which are integral parts of this document. 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);
30、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 t
31、o 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
32、 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
33、 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.

BS EN 1057:2006+A1:2010EN 1057:2006+A1:2010 (E) 6 Introduction Products in conformity with this European Standard are consider
39、ed suitable for drinking water applications subject to either a) compliance with any national regulations in the country of intended destination; or b) compliance in due course with the proposed European Acceptance Scheme (EAS) that will introduce common EU requirements for testing for fitness for c
40、ontact with drinking water. When the EAS is implemented, this European Standard will have added to it a special Annex (Z/EAS) to incorporate the provi-sions of the EC mandate M/136 and a) will no longer be applicable. This European Standard provides the basis for the assessment of a manufacturers pr
41、oduction process for products manufactured in accordance with this European Standard. The assessment could be based on initial and continuing surveillance of the factory production control system which could be concurrent with an assessment of the manufacturers quality management system against EN I
42、SO 9001. Regulatory marking and the means by which regulatory marking is applied, is dealt with in Annex ZA. Tubes having an outside diameter of not more than 108 mm are suitable for soldering, brazing or assembling by mechanical compression, collared, push-fit or press fittings. For tubes having an
43、 outside diameter of more than 108 mm, assembly should preferably be performed by welding or braze welding. Reference can be made to this European Standard for tubes intended for other applications or for the transportation of other fluids. In such cases special requirements (for specifications, con
44、ditioning or delivery conditions) can be agreed between the purchaser and the supplier. NOTE Appropriate precautions should be taken if applying insulating/protecting material because it could be detrimental to the copper tube. BS EN 1057:2006+A1:2010EN 1057:2006+A1:2010 (E) 7 1 Scope This European
45、Standard specifies the requirements, sampling, test methods and conditions of delivery for seam-less round copper tubes. It is applicable to tubes having an outside diameter from 6 mm up to and including 267 mm for: distributing networks for hot water and cold water; hot water heating systems, inclu
46、ding 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. 2 Normative references The following referenced doc
