17、ust 1998.It is the revision of the standard adopted by CEN in 1991.Main changes concern:scope;materials;weld joint design;calculations coefficient;flange calculations;reinforcement of openings;supports;testing and inspection;instruction and marking;corrosion allowance.Although the requirements of th
18、is standard support the essential safety requirements of the Simple pressure vessel Directive 87/404/EEC,that directive does not make compliance with this standard mandatory.This standard includes an interpretation of the conformity assessment requirements of the directive and thus the national impl
19、ementing legislation.These interpretations cannot be taken as having any formal status and carry the risk of misinterpretation.Users of this standard should,therefore,refer to the applicable national legislation for the definitive conformity assessment requirements.A further revision of this standar
20、d is being prepared to remove any misleading provisions.This standard is one of four within the series Simple unfired pressure vessels designed to contain air or nitrogen.The other standards are:Part 2:Pressure vessels for air braking equipment and auxiliary systems for motor vehicles and their trai

22、 has been prepared for use in conjunction with the informative Annex G of this European Standard.No rules of construction can be written in sufficient detail to ensure good workmanship and construction.Each manufacturer is responsible for taking every necessary step to make sure that the quality of
23、workmanship and construction is such as to ensure compliance with good engineering practice.Aspects of quality assurance are dealt with in various clauses and annexes of this standard;for example in Clause 10,Testing;and in Annex A,Verification;Annex B,Declaration of conformity Surveillance;Annex C,
24、Design and manufacturing schedule;Annex D,Type examination;Annex E,Content of the manufacturing record,all of which form part of this standard.These are minimum requirements,having taken into account EN ISO 9002 Quality systems Model for quality assurance in production,installation and servicing and
25、 EN ISO 9003 Quality systems Model for quality assurance in final inspection and test,but it is not implied that a quality system in accordance with EN ISO 9002 and EN ISO 9003 is necessary.This European Standard has been prepared under a mandate given to CEN by the European Commission and the Europ

37、ls,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 cylindrical part of ci
38、rcular cross-section closed by outwardly dished and/or flat ends which revolve around the same axis as the cylindrical part;or2)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.1.2 It app
39、lies 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 b
40、e made either of non-alloy quality steel or of non-alloy aluminium or non-age-hardening aluminium alloys;NOTEIn this part of the standard,the term“aluminium”covers non-alloy aluminium and aluminium alloys.c)the maximum working pressure is not greater than 30 bar.The product of the maximum working pr
41、essure 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 the maximum working temperature
42、 is not higher than 300?C for steel and 100?C 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
43、 to transportation vessels nor to vessels which also contain substances other than air or nitrogen which could adversely affect their safety.For vessels designed to contain compressed air for the braking systems of road vehicles and their trailers,see also EN 286-2.For vessels designed to contain co
44、mpressed air for the braking systems of rail-mounted vehicles,see also EN 286-3 and EN 286-4.1.3 It applies to the vessel proper,from the inlet connection to the outlet connection and to all other connections required for valves and fittings.If bosses/pipes are used,the requirements specified herein
45、 begin or end at the weld where flanges,if used,would have been fitted.1.4 For the purposes of calculations required to be made in accordance with this standard,dimensions are in millimetres,pressures are in bars(except where otherwise specified),stresses are in newtons per square millimetre and tem
46、peratures are in degrees Celsius.2 Normative referencesThis European Standard incorporates,by dated or undated reference,provisions from other publications.These normative references are cited at the appropriate places in the text and the publications are listed hereafter.For dated references,subseq
