24、with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carrie

25、d 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. IS

26、O 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 Internatio

27、nal 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. Attention is drawn to the possibility that some of the ele

28、ments of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 5774 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Hoses (rubber and plastics). This third edition cancels

29、and replaces the second edition (ISO 5774:1997), which has been technically revised. BS EN ISO 5774:2008Copyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-vIntroduction This Interna

30、tional Standard has been prepared to provide minimum acceptable requirements for the satisfactory performance of flexible thermoplastics hoses, textile reinforced, for compressed-air applications. Maximum working pressures of each hose type are specified with two operating temperatures. Some hose ma

31、terials will require a hydrolysis test (given in Annex A).

33、thermoplastic hose, textile reinforced, for compressed-air applications in the temperature range from 10 C to + 60 C. The four types are classified as light service for a maximum working pressure of 7 bar at 23 C and 4,5 bar at 60 C, medium service for a maximum working pressure of 10 bar at 23 C an

34、d 6,5 bar at 60 C, heavy service for a maximum working pressure of 16 bar at 23 C and 11 bar at 60 C, and heavy service for use in mining for a maximum working pressure of 25 bar at 23 C and 13 bar at 60 C. 2 Normative references The following referenced documents are indispensable for the applicati

41、es depending on their pressure rating at the specified temperature: Type A: General industrial use light service for a maximum working pressure of 7 bar at 23 C and 4,5 bar at 60 C. Type B: General industrial use medium service for a maximum working pressure of 10 bar at 23 C and 6,5 bar at 60 C. Ty

42、pe C: Heavy service for a maximum working pressure of 16 bar at 23 C and 11 bar at 60 C. Type D: Heavy service for use in mining and outdoor work for a maximum working pressure of 25 bar at 23 C and 13 bar at 60 C. The hoses are not intended for the transport of oil. However, compressed air coming f

43、rom a compressor may contain some oil in suspension. 5 Couplings and end fittings Hoses may be fitted with the appropriate coupling type and end fitting to form hose assemblies. NOTE Guidance on coupling type is given in Annex D and ISO/TR 17784. 6 Materials and construction The hoses shall consist

44、of: a) a lining made of a flexible thermoplastics material; b) a reinforcement made of a natural or synthetic textile material applied by any suitable technique; c) a cover made of a flexible thermoplastics material. The lining and the cover shall be of uniform thickness, concentric, fully gelled an

45、d free from visible cracks, porosity, foreign inclusions and any other defects which could cause the hose to be unserviceable. 7 Dimensions and tolerances 7.1 Inside diameter, tolerances and minimum wall thickness When measured in accordance with ISO 4671, the inside diameter of hoses shall lie with

46、in the tolerance limits given in Table 1 and the wall thickness shall meet the minimum requirement given in the table.
