14、ef. No. EN 286-1:1998 E + A2 October 2005 BSI 20072 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

15、 an identical text or by endorsement, at the latest by August 1998, and conflicting national standards shall be withdrawn at the latest by August 1998.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; flan

16、ge calculations; 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

17、 with this standard 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

18、standard should, 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 de

19、signed 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 trailers; Part 3: Steel pressure vessels designed for air braking equipment and auxiliary pneumatic equipment for railway rolling stock; P

20、art 4: Aluminium 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

21、 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 workmanship and construction is such as to ensure compliance with good engineering practice. Aspects of quality assurance are d

22、ealt 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, Design and manufacturing schedule; Annex D, Type examination; Annex E, Content of the manufacturing record, all of whi

23、ch 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 EN ISO 9003 Quality systems Model for quality assurance in final inspection and test, but it is not implied t

24、hat 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 European Free Trade Association, and supports essential requirements of EU Directive(s). The general layout of th

25、e standard was 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,

26、 Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

39、 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 fabrication by welding, but some desi

40、gns 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 cylindrical part; or 2) two outwa

41、rdly 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 operate within the followin

42、g 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; NOTE In this part of the

43、 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 bar l. Below 50 bar l, us

44、e 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. It does not apply to vessel

45、s 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 coul

46、d 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 286-3 and EN 286-4. 1.3 It appl

47、ies 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. 1.4 For the purposes of cal

48、culations 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 European Standard incorporates,
