BS EN 14638-3:2010 EN 14638-3:2010 (E)4 Introduction The purpose of this European Standard is to provide a specific
21、ation for the design, manufacture, inspection and approval of welded carbon steel gas cylinders for use in the countries of the CEN members. The specifications given in the present standard establish the methodology to be adopted to demonstrate that a cylinder conforms to the functional requirements
22、 demanded, based on experience of materials, design prescriptions, manufacturing processes and controls manufacturing. This European Standard specifies experimental methods and appropriate stress analysis calculations. It does not cover methods exclusively by means of traditional calculation. BS EN
23、14638-3:2010 EN 14638-3:2010 (E)5 1 Scope This European Standard specifies minimum requirements concerning material, design, construction and workmanship, procedures and tests at manufacture of refillable transportable welded cylinders made of carbon steel, justified by experimental methods, of wate
24、r 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 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 t
