ISO 13338:2017 provides:
- for pure gases and some liquids, a complete list indicating their corrosiveness;
- for gas mixtures, a calculation method, in the absence of experimental data, relating to the corrosiveness of each of their components;
in order to determine the corrosiveness of gases and gas mixtures on tissue so that a suitable outlet connection can be assigned to each of them.
