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of an identical text or by endorsement, at the latest by November 2006, and conflicting national standards shall be withdrawn at the latest by February 2008. This document supersedes EN 1057:1996. Within its programme of work, Technical Committee CEN/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

EN 1057:2006 (E) 6 Introduction Products in conformity with this European Standard are considered 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 contact 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 manufacturer's production 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
manufacturer's quality management system against EN ISO 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 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, conditioning 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. SIST EN 1057:2006
EN 1057:2006 (E) 7 1 Scope This European 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, 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. 2 Normative references The following referenced documents are indispensable for the application of this document.
