This standard BS EN ISO 21012:2024 Cryogenic vessels. Hoses is classified in these ICS categories:
23.020.40 Cryogenic vessels
83.140.40 Hoses
This document specifies design, construction, type and production testing, and marking requirements for both non-insulated cryogenic flexible hoses and insulated vacuum jacketed hoses used for the transfer of cryogenic fluids within the following range of operating conditions: — working temperature range: 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.
