Omfang

ISO 21012:2018 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.ISO 21012:2018 is intended that the hose be designed and tested to satisfy the generally accepted rated pressure i.e. at least PR 40. 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.
