Optionally co-design standards:
This standard gives design, construction, type and production testing, and marking requirements for non insulated
cryogenic flexible hose used for the transfer of cryogenic fluids within the following range of operating conditions :
working temperature: from - 270 °C to + 65 °C ;
maximum nominal pressure: 80 bar ;
nominal size (DN): from 10 to 100.
End fittings for mounting of any couplings are within the scope of this standard, but the couplings are subject to
other standards.
It is intended that the hose be designed and tested to satisfy the generally accepted nominal pressure e.g. PN 40.
Hoses may then be selected with a PN equal to or greater than the maximum allowable pressure (PS) of the
equipment to which it is to be used.
