DIN EN 14638-3:2012-06 EN 14638-3:2010 + AC:2012 (E)4 Introduction The purpose of this European Standard is to provide a specification for the design, manufacture, inspection and approval of welded carbon steel gas cylinders for use in the countries of the CEN members. The specifica
24、tions given in the present standard establish the methodology to be adopted to demonstrate that a cylinder conforms to the functional requirements demanded, based on experience of materials, design prescriptions, manufacturing processes and controls manufacturing. This European Standard specifies ex
25、perimental methods and appropriate stress analysis calculations. It does not cover methods exclusively by means of traditional calculation. DIN EN 14638-3:2012-06 EN 14638-3:2010 + AC:2012 (E)5 1 Scope This European Standard specifies minimum requirements concerning material, design, construction an
26、d workmanship, procedures and tests at manufacture of refillable transportable welded cylinders made of carbon steel, justified by experimental methods, of water capacities from 0,5 l up to and including 150 l for compressed or liquefied gases and of a test pressure up to 90 bar. NOTE This European
27、Standard may also be used as a guideline for cylinders less than 0,5 l water capacity. This European Standard is primarily intended for industrial gases other than LPG but may also be applied for LPG. However, for dedicated LPG cylinders see EN 14140 5, prepared by CEN/TC 286. 2 Normative references
