12、7 BS ISO 19013-1:2005iv 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
13、 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 Commiss
14、ion (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 International Standards. Draft International Standards adopted by the technical
15、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 document may be the subject of patent rights. ISO shall
16、not be held responsible for identifying any or all such patent rights. 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,
17、 ISO 4639-2:1995 and ISO 4639-3:1995, which have been technically 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 BS ISO 19013-1:20051Rubbe
18、r hoses and tubing for fuel circuits for internal combustion engines Specification Part 1: Diesel fuels WARNING Persons using this part of ISO 19013 should be familiar with normal laboratory practice. This part of ISO 19013 does not purport to address all of the safety problems, if any, associated w
19、ith 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 19013 specifies the requirements for rubber tubing and hoses used in diesel fuel circuits for internal com
20、bustion engines. 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 (O
21、EMs) to detail 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 m
