1 Scope
This International Standard gives design, construction, type and production testing, and marking requirements for non-insulated cryogenic flexible hoses used for the transfer of cryogenic fluids within the following range of operating conditions:
-
— working temperature: from − 270 °C to − 65 °C;
-
— nominal size (DN): from 10 to 100.
End fittings for mounting of any couplings are within the scope of this International Standard, but the couplings are subject to other standards.
