BS EN 1057:2006+Amendment 1:2010

Copper and copper alloys. Seamless, round copper tubes

Products in conformity with BS EN 1057 are considered suitable for drinking water applications subject to either:

a) compliance with any national regulations in the country of intended destination

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, BS EN 1057 will have added to it a special Annex (Z/EAS) to incorporate the provisions of the EC mandate M/136 and a) will no longer be applicable.

BS EN 1057 is the standard that 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 also covered in BS EN 1057.

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.

Appropriate precautions should be taken if applying insulating/protecting material because it could be detrimental to the copper tube.

BS EN 1057 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 also applies to seamless round copper tubes intended to be pre-insulated before use for any of the above purposes.
