22、 cryogenic vessels designed for a maximum allowable pressure of more than 0,5 bar. This European Standard is applicable to static vacuum insulated cryogenic vessels for fluids as specified in EN 13458-1, and does not apply to vessels designed for toxic fluids. For static vacuum insulated cryogenic v
23、essels designed for a maximum allowable pressure of not more than 0,5 bar this standard can be used as a guide. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
