Description
New technologies emerging from High-Energy Physics labs are quickly being deployed in large scales not only within the research infrastructures but also transferred to other commercial and industrial applications. Therefore, standardization of these innovative systems and equipment is essential to ensure an acceptable level of safety and quality, in which the cooperation between research and industry is vital.
In the cryogenic safety domain, as compared to cryogenic storage vessels, helium cryostats include active components such as superconducting devices, heaters, pumps and control valves, which strongly influence the risk of excessive pressure. The European Standard "Helium cryostats – protection against excessive pressure" is therefore being developed by the working group CEN/TC 268/WG6, dealing with specific helium technology applications.
The new European Standard counts with the participation of several experts from the HEP community and main industry partners in this field. The standard will be applicable to all helium cryostats, including e.g. superconducting magnet cryostats and cryostats for superconducting radio-frequency cavities. It covers typical accidental scenarios in order to harmonise the risk assessment and common practice for the dimensioning and the design of pressure relieving systems. The EN standard is aimed to be harmonized with the European Pressure Equipment Directive.
We report on the general structure and conceptual improvements of the new Standard, as well as on the present work status.
