10、ion 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 h

11、as 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. Int

12、ernational 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. Public

13、ation 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 such patent ri

14、ghts. ISO 19013-1 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Hoses (rubber and plastics). Together with Part 2 (see below), this part of ISO 19013 cancels and replaces ISO 4639-1:1987, ISO 4639-2:1995 and ISO 4639-3:1995, which have been technically

15、 revised. ISO 19013 consists of the following parts, under the general title Rubber hoses and tubing for fuel circuits for internal combustion engines Specification: Part 1: Diesel fuels Part 2: Gasoline fuels INTERNATIONAL STANDARD ISO 19013-1:2005(E) ISO 2005 All rights reserved 1Rubber hoses and

This part of ISO 19013 does not purport to address all of the safety problems, if any, associated with its use.

17、 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 19013 specifies the requirements for rubber tubing and hoses used in diesel fuel circuits for internal combustion engi

18、nes. The diesel fuels covered include “bio-diesels” which consist of the methyl ester of rape seed oil at levels up to 20 % by volume in conventional diesel fuels. In addition, this specification may also be applied as a classification system to enable original equipment manufacturers (OEMs) to deta

19、il a “line call-out” of tests for specific applications where these are not covered by the main types specified (see example in Annex E). In this case, the hose or tubing would not carry any marking showing the number of this part of ISO 19013 but may detail the OEMs own identification markings as s
