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 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 3. 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 elements of this part of ISO 13775 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 13775-2 was prepared by Technical Committee ISO/TC 45,Rubber and rubber products, Subcommittee SC 1,Hoses (rubber and plastics). ISO 13775 consists of the following parts, under the general titleThermoplastic tubing and hoses for automotive use: Part 1: Non-fuel applications Part 2: Petroleum-based-fuel applications Annexes A, B and C of this part of ISO 13775 are for information only. Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 26 06:53:18 GMT+00:00 2006, Uncontrolled Copy, (c) BSI ISO 13775-2:2000(E) ?v Introduction This specification defines the requirements of extruded thermoplastic tubing/hoses for petroleum-based-fuel applications for automotive use. In addition, it may also be applied as a classification system to enable original equipment manufacturers (OEMs) to detail a “line call-out” of tests for specific applications where these are not covered by the six main types (see example in annex A). In this case, the tubing or hose would not carry any marking showing this ISO specification number, but may detail the OEMs own identification markings as shown on their part drawings.

This part of ISO 13775 does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. 1?Scope This part of ISO 13775 specifies test requirements and test methods for extruded thermoplastic tubing and hoses for use in petroleum-based-fuel lines in vehicles powered by internal-combustion engines. This specification is intended especially for use by original equipment manufacturers (OEMs). 2?Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 13775.

The product may also have an inner veneer to impart improved fluid resistance and/or reduced fuel vapour permeability. It may also have an extruded outer cover to improve environmental resistance and/or flame resistance. The outer cover is not necessarily bonded to the tubing or hose. Six types of tubing and hose for specific applications are specified as follows: Type 1: feed and return lines from the fuel tank to the engine compartment gasoline engines; Type 2: feed and return lines from the fuel tank to the engine compartment diesel engines; Type 3: feed and return lines in the engine compartment moderate-temperature (100 ?C) environment gasoline engines; Type 4: feed and return lines in the engine compartment high-temperature (125 ?C) environment gasoline engines; Type 5: feed lines in the engine compartment diesel engines; Type 6: multi-layer tubing or hoses for vapour lines. 4?Dimensions Bore diameters and wall thicknesses shall be as given in Table 1. The wall thickness shall be the sum of the individual thicknesses of the various elements in the construction of the tubing or hose. The thickness of each individual element shall be such that it is able to carry out its own function and the total function of the tubing or hose.
