Data sheet: Copper tubes for medicinal applications

Bronmetal are experts in the supply of round copper tubes for medical use. All of them are applied according to the EN 13348 Standard which specifies the requirements, sampling, test methods and supply conditions for this type of product. In our catalogue you can select the mechanical characteristics of these copper tubes according to the state of treatment: annealed, semi-hard or hard. This classification is determined according to the EN 1173 Standard which establishes a system for the designation of material states to be used for the identification of mandatory property requirements

Each tube must be capped, plugged or closed at both ends to keep the interior of the tube properly clean for handling and storage. The interior surface of the tube must be able to successfully pass carbon content testing. When lubricant residue is measured on the interior surface of the tube, it must not exceed 0.020 g/m2


This norm specifies the requirements, sampling, test methods and conditions of supply for copper tubes. It is applicable to round copper tubes without welding which have an exterior diameter from 8 mm up to and including 54 mm, for piping systems used for the distribution of the following medicinal gases, intended for use at pressures up to 2000KPa, and for systems subjected to vacuums:
  • oxygen, nitrous oxide, nitrogen, helium, carbon dioxide, xenon.
  • air for breathing.
  • specific mixtures of gases mentioned above.
  • air for driving surgical tools
  • anesthetic gases and vapors.
  • vacuums.
