DIN EN 13348:2016-11

This standard specifies the requirements, sampling, test methods and conditions of delivery for copper tubes. It is applicable to seamless round copper tubes having an outside diameter from 6 mm up to and including 219 mm for pipeline systems under vacuum or for distributing the following medical gases intended to be used at operating pressures up to 2 000 kPa:
- oxygen, nitrous oxide, nitrogen, helium, carbon dioxide, xenon;
- medical air;
- specific mixtures of these above mentioned gases;
- air for driving surgical tools;
- anaesthetic gases and vapours.
Tubes according to this standard are suitable for capillary soldering (soft or hard soldering) or for assembly by means of compression fitting or flared connectors.
It is advised to take appropriate precautions if applying insulating material because it could be detrimental to the copper tube.
