18、O (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical co
19、mmittee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electro
20、technical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the me
21、mber bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. ISO 10806 was prepared by Technical Committee ISO/TC 5, Ferrous metal pipes and metallic fittings, Subcommittee SC 11, Metal hoses and expansion joints. This secon
22、d edition cancels and replaces the first edition (ISO 10806:1994), which has been technically revised. ENISO10806:2003iv Introduction It was decided to produce a standard under the Vienna agreement on technical cooperation between ISO and the European Committee for Standardization (CEN) in order to
23、maintain one standard. The opportunity was taken to add additional information not available for the first edition of ISO 10806. The major changes are: addition of a clause on design; revision of the type descriptions and the symbols; addition of conical nipples and adaptors; addition of three serie
24、s of fixed flanges; deletion of the PN 16 loose plate flange series. ENISO10806:2003INTENRATIONAL TSANDADR IS:60801 O3002(E)1Pipework Fittings for corrugated metal hoses 1 Scope This International Standard specifies the characteristics of fittings for corrugated metal hose conforming with the requir
25、ements of ISO 10380. This International Standard is also valid for other fittings provided they meet the material, design, assembly and test requirements specified herein. 2 Normative references The following referenced documents are indispensable for the application of this document.

30、finition and selection of PN ENISO10806:20032 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 7369 apply. 4 Information to be supplied by the purchaser 4.1 The purchaser shall state the following in enquiries and orders: a) intended application; b) n
31、ominal size; c) maximum operating pressure; d) materials of construction; e) temperature range; f) type of fitting 1) as specified in Table 1, or 2) as specified by the purchaser. 4.2 Depending on the application, the purchaser shall provide a) product to be conveyed; b) any special information conc
32、erning choice of materials; c) requirements for test certificates; d) any special requirements for packaging. 5 Requirements 5.1 Classification Fittings are classified as follows: a) welded screwed, b) welded stub, c) welded flanged, d) adaptors, and e) those specified in Table 1. ENISO10806:2003 35
33、.2 Materials Materials for the parts of end fittings that are welded or brazed shall be selected from those listed in ISO 10380:2003, Table 1. The use of materials other than these shall be subjected to agreement between the manufacturer and the user. Materials for other parts of the fittings shall
34、be selected from ISO standardized materials and on the basis of their suitability for the conditions under which the hose assemblies will be used. 5.3 Dimensions Fitting dimensions shall be as given in Tables 3 to 13. 5.4 Design 5.4.1 Pressure Welded screwed, welded stub and adaptor fittings shall b
35、e specified to be in accordance with the pressures given in ISO 10380:2003, 5.3.1.1. Pressures for welded flanged fittings shall be as specified in Tables 11 to 15. These pressures are in accordance with ISO 7268 and EN 1333. Where assemblies consist of fittings with different allowable or nominal p
36、ressures, the lower value shall be used for the assembly. 5.4.2 Temperature For temperatures below 20 C or exceeding 50 C, reference shall be made to the derating factors in ISO 10380:2003, Table 3. 5.5 Method of assembly The fittings shall be joined to the hose as specified in ISO 10380:2003, 5.8.
37、6 Type tests 6.1 General All types of welded fitting listed in Table 1 shall be permanently joined to a tube or corrugated metal hose according to the method specified in ISO 10380. They are then assembled as a test assembly, as shown in Table 2. The test medium shall be water unless otherwise agree
38、d by the purchaser. 6.2 Leakage test Subject a test assembly to an hydraulic pressure of 1,5 times the maximum allowable pressure for a minimum of 1 min. The sealing faces of the fittings shall show no signs of visible leakage. 6.3 Burst test Subject a test assembly to an hydraulic pressure applied
39、gradually in increments over a minimum period of 1 min until the assembly fails by leakage or rupture of any of the components, and note the pressure. The burst pressure of the fitting test assembly shall not be less than four times the maximum allowable pressure. ENISO10806:20034 7 Designation The
