BS EN 286-1:1998 + A2:2005 Simple unfired pressure vessels designed to contain air or nitrogen. Pressure vessels for general purposes
BS EN 286-1 is the European standard applicable to the design and manufacture of welded, simple unfired pressure vessels manufactured in series, with a single compartment. The standard also includes the essential safety requirements.
It applies to vessels that:
• Include fabrication by welding, but some designs can entail the use of bolts;
• Have a simple geometry enabling simple-to-use production procedures
• Have branches not larger in diameter than 0,5 of the diameter of the cylinder to which they are welded.
• Are intended to contain air or nitrogen that are not intended to be fired and that 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 of non-alloy aluminium or non-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 x V) is greater than 50 bar 1 but does not exceed 10 000 bar 1
d) the minimum working temperature is not lower than -50 oC, and the maximum working temperature is not higher than 300 oC for steel and 100 oC for aluminium or aluminium alloy vessels.
It does not apply to vessels specifically designed for nuclear use, to vessels specifically intended for installation in, or the propulsion of, ships and aircraft, nor to fire extinguishers.
The standard does not apply to transportation vessels nor to vessels which also contain substances other than air or nitrogen which could adversely affect their safety.
BS EN 286-1:1998 replaces BS EN 286-1:1991 which has been withdrawn.
