The European Standard "Helium cryostats - protection against excessive pressure" is being developed by the working group CEN/TC 268/WG6, dealing with specific helium technology applications.
The new European Standard will be applicable to all helium cryostats, including e.g. superconducting magnet cryostats and cryostats for superconducting radio-frequency cavities, to cold-boxes of helium refrigerators and liquefiers, to ultra-low temperature refrigerator systems using He-3 and He-3/He-4 mixtures as well as to helium distribution systems. It covers typical accidental scenarios in order to harmonise the risk assessment.
