This European 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.
