The certification mark applies to compressed gas canisters and non-refillable metallic gas cartridges.
The certification mark is based on the EN 417 standard. The standard defines aspects including the important features that cartridges for liquefied gases must have. It also defines the procedures and requirements on which type testing is based.
The voluntary certification mark with the statement “Safety tested” is issued for products, indicating that the product was tested and certified by the independent third-party organisation of TÜV SÜD Product Service for conformity with the essential technical safety requirements.
