The work of preparing International Standards is normally carried out through ISO
12、 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 cl
13、osely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria
14、 needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of pat
15、ent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used

19、ATIONAL STANDARD ISO 19013-2:2016(E)Rubber hoses and tubing for fuel circuits for internal combustion engines Specification Part 2: Gasoline fuelsWARNING 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
20、 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 ScopeThis part of ISO 19013 specifies the requirements for rubber tubing and hoses used
21、in gasoline fuel circuits for internal combustion engines. The gasoline fuels covered include those containing oxygenates such as methanol and fuels that have become oxidized (“sour gas”). In addition, this part of ISO 19013 can also be applied as a classification system to enable original equipment
22、 manufacturers (OEMs) 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 G). 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 ow
23、n identification markings as shown on their part drawings.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
