16、echnical Committee CEN/TC 342 “Metal hoses, hose assemblies, bellows and expansion joints”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2006, and

17、conflicting national standards shall be withdrawn at the latest by July 2006. 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) 97/23/EC 1. For relationship

18、with EU Directive(s), see informative Annex ZA, which is an integral part of this European Standard. This standard provides one means of conforming to the related essential requirements. This standard has been produced to address the specific needs of corrugated metal hose assemblies for pressure ap

19、plications using, and when necessary supplementing, the requirements of EN ISO 10380 “Pipework Corrugated metal hoses and hose assemblies” which is the base standard for hoses and hose assemblies for general purposes. This standard consists of 2 parts: EN 14585-1 “Corrugated metal hose assemblies fo

20、r pressure applications Part 1 Requirements”; prCEN/TR 14585-2 “Corrugated metal hose assemblies for pressure applications Part 2 Guidance for the use of conformity assessment procedures”. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countr

21、ies are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden,

22、Switzerland and United Kingdom. EN 14585-1:2006 (E) 4 Introduction The requirements of this standard concern designers, manufacturers, suppliers and importers of corrugated metal hose assemblies for pressure application. The unique nature of a corrugated metal hose assembly is characterised: by the

23、interactive role of its pressure bearing parts: corrugated metal hose, braid, fittings and its permanent joints; and by the opposing requirements of pressure resistance and flexibility. PED, Annex I, Clause 2.2.2 as a general rule limits the experimental design method for piping to PSDN less than 30

24、00. For the time being there is no officially recognised calculation method available to design hose assemblies. Accordingly it is essential that validation tests support design for all values of PS.DN. EN 14585-1:2006 (E) 5 1 Scope This European Standard specifies the requirements for material, des

25、ign, manufacturing, testing and documentation for corrugated metal hose assemblies for pressure applications for use with a maximum allowable pressure PS greater than 0,5 bar. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

38、ad at ambient 4 Classification Pressure hose assemblies are classified by the manufacturer using diagrams (see Figures A.1, A.2, A.3 and A.4) into SEP pressure hose assemblies or CAT pressure hose assemblies that lead in the following clauses to different requirements and evaluation procedures. Thei

39、r classification depends on DN and PS and on the type of fluid they contain according to Table 1. When a pressure hose assembly has different DNs along its length, the classification shall be determined by the largest DN section of the pressure hose assembly. Where a pressure hose assembly can be su

40、bjected to different working conditions, the classification shall be made on the basis of the more severe working conditions. Where a pressure hose assembly can contain several fluids, the classification shall be made on the basis of the fluid of the highest category. Table 1 Classification of the p

41、ressure hose assemblies Fluid Dangerous fluids in Group 1 (explosive, extremely flammable, highly flammable, flammable - where the maximum allowable temperature is above flashpoint - very toxic, toxic and oxidizing) Other fluids in Group 2 Gases, liquefied gases, gases dissolved under pressure, vapo

42、urs and liquids with a vapour pressure at maximum allowable pressure greater than 0,5 bar above normal atmospheric pressure (1013 mbar) Fluids in Group 1 with a DN greater than 25 (see also Figure A.1) Fluids in Group 2 with a DN greater than 32 and a product of PS and DN greater than 1000 bar (see

43、also Figure A.2) Liquids having a vapour pressure at maximum allowable temperature (TS) of more than 0.5 bar above normal atmospheric pressure (1013 mbar) Fluids in Group 1 with a DN greater than 25 and a product of PS and DN greater than 2000 bar (see also Figure A.3) Fluids in Group 2 with a PS gr

44、eater than 10 bar, a DN greater than 200 and a product of PS and DN greater than 5000 bar (see also Figure A.4) CAT pressure hose assemblies are also sub-classified into categories (I, II and III) depending on DN and PS and on the type of fluid they contain, see prCEN/TR 14585-2. NOTE 1 The demarcat

45、ion lines in the Figures A.1 to A.4 defining the limits between the SEP and CAT pressure hose assemblies belong to the SEP pressure hose assembly. NOTE 2 National regulations transposing the Council Directive 67/548/EC 2 of 27 June 1967 on classification of dangerous substances should be considered.

46、 In case of doubt regarding the group to which a fluid belongs, the manufacturer should obtain the information from the user. EN 14585-1:2006 (E) 8 NOTE 3 Particular care should be taken with unstable gases such as acetylene, methyl acetylene, vinylfluoride etc. 5 SEP pressure hose assemblies The re
