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 committee 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 electrotechnical 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 member 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 second edition cancels and replaces the first edition (ISO 10806:1994), which has been technically revised.

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 series of fixed flanges; deletion of the PN 16 loose plate flange series.

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 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 be 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 pressures, 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. 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 agreed 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 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.
