Copper and copper alloys - Seamless, round copper tubes for water and gas in sanitary and heating applications

BS EN 1057 is one of the European standards for copper and copper alloy tubes. Copper tubes in conformity with this standard are considered suitable for drinking water applications.

  • Copper tubes having outside diameter ≤ 108mm: suitable for soldering, brazing or assembling by mechanical compression, collared, push-fit or press fittings.
  • Copper tubes having outside diameter ﹥ 108mm: assembly should preferably be performed by welding or braze welding.

Application of BS EN 1057 Copper Tubes

BS EN 1057 specifies the requirements, sampling, test methods and conditions of delivery for seamless round copper tubes. The outside dimater of copper tubes range from 6mm up to and including 267mm for belowing applications:

  • 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

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

Composition of copper tubes

The copper grade is designated eigther Cu-DHP or CW024A, the composition requirements as below.

Cu + Ag 99.90% (min)

0.015% ≤ P ≤0.040%

Tolerances on wall thickness

e ﹤ 1mm

Tolerances on wall thickness ea

e ≥ 1mm

d ﹤ 18mm ± 10% ± 13%
d ≥ 18mm ± 10% ± 15b
Note: Concentricity (uniformity of wall thickness) is controlled by tolerance on wall thickness

a including deviation from concentricity

b ± 10% for R250 (half hard) tubes of 35mm, 42mm and 54mm diameters with a wall thickness of 1.2mm

Tolerances on length

The length of BS EN 1057 copper tubes should be equal to or greater than ordered length.
