BS EN 14638-1:2006 – Transportable gas cylinders — Refillable welded receptacles of a capacity not exceeding 150 litres — Part 1: Welded austenitic stainless steel cylinders made to a design justified by experimental methods
1 Scope
This European Standard gives minimum requirements concerning material, design, construction and workmanship, procedures and tests at manufacture of refillable transportable welded cylinders made of austenitic stainless steel, justified by experimental methods, of water capacities from 0,5 l up to and including 1 50 l for compressed or liquefied gases and of a test pressure up to 90 bar.
NOTE This European Standard may also be used as a guideline for cylinders less than 0,5 litres water capacity. This European Standard is primarily for industrial gases other than LPG but may also be applied for LPG. However for dedicated LPG cylinders, see EN 14140, Transportable refillable welded steel cylinders for liquefied petroleum gas (LPG) – Alternative design and construction prepared by CEN/TC 286 Liquefied petroleum gas equipment and accessories.
