13、 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of an identical text or by endorsement, at the latest by July 2006, and conflicting national standards shall be withdrawn at the latest by July 2006. This European Standard has been prepared under
14、 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 with EU Directive(s), see informative Annex ZA, which is an integral part of this European Standard. This standard provides
15、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 applications using, and when necessary supplementing, the requirements of EN ISO 10380 “Pipework Corrugated metal hoses and ho
16、se 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 for pressure applications Part 1 Requirements”; prCEN/TR 14585-2 “Corrugated metal hose assemblies for pressure applications P
17、art 2 Guidance for the use of conformity assessment procedures”. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, Fran
18、ce, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 14585-1:2006 (E) 4 Introduction The requirements of this standard concern designers, manu
19、facturers, suppliers and importers of corrugated metal hose assemblies for pressure application. The unique nature of a corrugated metal hose assembly is characterised: by the interactive role of its pressure bearing parts: corrugated metal hose, braid, fittings and its permanent joints; and by the
20、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 3000. For the time being there is no officially recognised calculation method available to design hose assemblies. Accordingly
21、 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, design, manufacturing, testing and documentation for corrugated metal hose assemblies for pressure applications for use with a
22、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.

35、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. Their classification depends on DN and PS and on the type of fluid they contain according to Table 1. When a pressure hose assem
36、bly 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 subjected to different working conditions, the classification shall be made on the basis of the more severe working conditions
37、. 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 pressure hose assemblies Fluid Dangerous fluids in Group 1 (explosive, extremely flammable, highly flammable, flammable - whe
38、re the maximum allowable temperature is above flashpoint - very toxic, toxic and oxidizing) Other fluids in Group 2 Gases, liquefied gases, gases dissolved under pressure, vapours and liquids with a vapour pressure at maximum allowable pressure greater than 0,5 bar above normal atmospheric pressure
39、(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 also Figure A.2) Liquids having a vapour pressure at maximum allowable temperature (TS) of more than 0.5 bar above normal at
40、mospheric 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 greater 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
41、 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 demarcation lines in the Figures A.1 to A.4 defining the limits between the SEP and CAT pressure hose assemblies belong to the SEP p
42、ressure 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. In case of doubt regarding the group to which a fluid belongs, the manufacturer should obtain the information from the user
