21、ional 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 committee has bee

22、n 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 stand

23、ardization. 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

24、 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 elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all

25、 such patent rights. ISO 1825 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Hoses (rubber and plastics). This third edition cancels and replaces the second edition (ISO 1825:1996), which has been technically revised (for details, see the Introduction).

26、 BS EN ISO 1825:2011ISO 1825:2010(E) ISO 2010 All rights reserved vIntroduction This specification has been updated to bring it into line with the two most common specifications used for this product in the field, EN 1361:2004 and API 1529, 6th edition. As the 1996 edition of ISO 1825 was closer to

27、EN 1361, EN 1361 was used as the basis for redrafting. Where possible, an attempt has been made to align all three specifications. As a result of this, the following changes have been made to the specification: a) type A (hoses without any special electrical properties) has been eliminated; b) type

28、D (hoses with a conductive cover but without a low-extraction tube compound) has been eliminated; c) there are now four hose types (all with a low-extraction tube); d) a hose flammability test has been introduced; e) a cyclic kinking test has been introduced; f) a flex test at 30 C has been introduc

29、ed; g) the flexibility at room temperature test is carried out at 20 C as opposed to 23 C originally.

30、 1 Scope This International Standard specifies the dimensions and construction of, and requirements for, four types of hose and hose assembly for use in all operations associated with the ground fuelling and defuelling of aircraft. All four types are designed for a) use with petroleum fuels having a

31、n aromatic-hydrocarbon content not exceeding 30 % by volume; b) operation within the temperature range of 30 C to +65 C and such that they will be undamaged by climatic conditions of 40 C to +70 C when stored in static conditions; c) operation at up to 2,0 MPa (20 bar) maximum working pressure, incl

32、uding surges of pressure which the hose can be subjected to in service. NOTE 1 Type C hoses are intended for general pressure applications on all vehicles used for plane fuelling. They can also be used for vehicle/rail car loading and discharge where excessive vacuum does not occur. NOTE 2 Type F ho

33、ses can be used for plane delivery applications on vehicles that are also used for defuelling at high flow rates where type C hoses are not suitable. NOTE 3 Type E and F hoses can also be used for vehicle/rail car loading and discharge, for trailer to fueller transfer and for elevation platform supp
