The work of preparing Internation
26、al 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,
27、 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 comm
28、ittees 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. Attention is drawn to the p
29、ossibility that some of the elements 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 plastic
30、s). This third edition cancels and replaces the second edition (ISO 5774:1997), which has been technically revised.

35、r 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 and 6,5 bar at 60 C, heavy service for a maximum working pr
36、essure 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 application of this document.

43、wing four types 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 ba
44、r at 60 C. Type 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
45、 air coming from 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 s
46、hall consist 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, fu
47、lly gelled and 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 within the tolerance limits given in Table 1 and the wall thickness shall meet the minimum requirement given in the table.
