CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
13、standards may be obtained on application to the Central Secretariat or to any CEN member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notifie

16、286-1:1998 + A1:2002 E EN 286-1:1998 Foreword This European Standard has been prepared by Technical Committee CEN/TC 54, Unfired pressure vessels, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical t
17、ext or by endorsement, at the latest by August 1998, and conflicting national standards shall be withdrawn at the latest by August 1998.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
18、; reinforcement of openings; supports; testing and inspection; instruction and marking; corrosion allowance. Although the requirements of this standard support the essential safety requirements of the Simple pressure vessel Directive 87/404/EEC, that directive does not make compliance with this stan
19、dard mandatory. This standard includes an interpretation of the conformity assessment requirements of the directive and thus the national implementing legislation. These interpretations cannot be taken as having any formal status and carry the risk of misinterpretation. Users of this standard should
20、, therefore, refer to the applicable national legislation for the definitive conformity assessment requirements. A further revision of this standard is being prepared to remove any misleading provisions. This standard is one of four within the series Simple unfired pressure vessels designed to conta
21、in air or nitrogen. The other standards are: Part 2: Pressure vessels for air braking equipment and auxiliary systems for motor vehicles and their trailers; Part 3: Steel pressure vessels designed for air braking equipment and auxiliary pneumatic equipment for railway rolling stock; Part 4: Aluminiu
22、m alloy pressure vessels designed for air braking equipment and auxiliary pneumatic equipment for railway rolling stock. This Part of this European Standard has been prepared for use in conjunction with the informative Annex G of this European Standard. No rules of construction can be written in suf
23、ficient detail to ensure good workmanship and construction. Each manufacturer is responsible for taking every necessary step to make sure that the quality of workmanship and construction is such as to ensure compliance with good engineering practice. Aspects of quality assurance are dealt with in va
24、rious 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, Design and manufacturing schedule; Annex D, Type examination; Annex E, Content of the manufacturing record, all of which form part of
25、 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 EN ISO 9003 Quality systems Model for quality assurance in final inspection and test, but it is not implied that a quality s
26、ystem 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 European Free Trade Association, and supports essential requirements of EU Directive(s). The general layout of the standard was
27、not changed and accordingly is not in full conformity with the recent CEN rules for harmonized standards. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic
28、, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

37、ean Standard applies to the design and manufacture of welded, simple unfired pressure vessels manufactured in series, with a single compartment, hereinafter referred to as vessels, the essential safety requirements of which are given in Annex G. It only applies to vessels that: a) include fabricatio
38、n 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 circular cross-section closed by outwardly dished and/or flat ends which revolve around the same axis as the cylind
39、rical 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. 1.2 It applies to vessels which are intended to contain air or nitrogen which are not intended to be fired and which
40、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 alloy
41、s; 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 pressure and the capacity of the vessel (PS?V) is greater than 50 bar?l but does not exceed 10 000
42、 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 is not higher than 300?C for steel and 100?C for aluminium or aluminium alloy vessels.
43、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
44、 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 compressed air for the braking systems of rail-mounted vehicles, see also EN 286-
45、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 begin or end at the weld where flanges, if used, would have been fitted.
46、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 temperatures are in degrees Celsius. 2 Normative references This Europ
