Scope

This document specifies 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 document, but the couplings are
subject to other standards.
It is intended that the hose be designed and tested to satisfy a rated pressure. Hoses may be then
selected with a PR equal to or greater than the maximum allowable pressure (PS) of the equipment to
which it is to be used.
