DANSK DS/EN 12434 PDF

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.
