Applies to the design and manufacture of welded, simple unfired pressure vessels manufactured in series, with a single compartment, here-in-after referred to as vessels, the essential safety requirements of which are given in annex G. It only applies to vessels that: a) include fabrication by welding, but some designs can entail the use of bolts; b) have a simple geometry enabling simple-to-use production procedures. This is achieved by either 1) a cilyndrical part of circular cross section closed by outwardly dished and/or flat ends which revolve around the same axis as the cilyndrical part; or 2) two outwardly dished ends revolving around the same axis; C) have branches not larger in diameter than 0,5 of the diameter of the cylinder to which they are welded. It applies to vessels which are intended to contain air or nitrogen which are not intended to be fired and which operate within the following constraints: a) subjected to an internal gauge pressure greater than 0,5 bar; b) the parts and assemblies contributing to the strength of the vessel under pressure to be made either of non-alloy quality steel or non-alloy aluminium or no-age hardening aluminium alloys; c) the maximum working pressure is not greater than 30 bar. The product of the maximum working pressure and the capacity of the vessel (PS.V) is greater than 50 bar. l but does not exceed 10.000 bar.l. Below 50 bar.l use of this standard is considered to fulfil the requirements of sound engineering practice; d) the minimum working temperature is not lower than -50°C and maximum working temperature not higher than 300°C for steel and 100°C for aluminium or aluminium alloy vessels.
