Overview

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 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 aforementioned purposes. Products in conformity with this European Standard are considered suitable for drinking water applications unless they are not subject to 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. Once the EAS has been implemented, a special Annex (Z/EAS) will be added to this European Standard to incorporate the provisions of the EC mandate M/136 and a) will no longer be applicable. This European Standard provides the basis for the assessment of the manufacturer's production process for products manufactured in accordance with this European Standard. The assessment may 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 in accordance with 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 (specifications, conditioning or delivery conditions) can be agreed between the purchaser and the supplier. Appropriate precautions should be taken if applying insulating/protecting material because it could be detrimental to the copper tube. This European Standard (EN 1057:2010) has been prepared by Working Group 3 "Copper tubes (Installation and industrial)" within Technical Committee CEN/TC 133 "Copper and copper alloys" (secretariat: DIN, Germany) of the European Committee for Standardization (CEN). During the preparation of this standard the national interests were represented by Working Committee NA 066-02-03 AA "Kupferrohre (Installation und Industrie)" ("Copper tubes (Installation and industrial)") of the Non-ferrous Metals Standards Committee (FNNE) at DIN, the German Institute for Standardization.
