13、eration 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 comm

14、ittee. 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.The procedures used to develop this document an

15、d those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria 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, Par

22、ems SpecificationWARNING Persons using this International Standard should be familiar with normal laboratory practice. This International Standard 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 sa

23、fety and health practices and to ensure compliance with any national regulatory conditions.1 ScopeThis International Standard specifies minimum requirements for three types of hoses in two categories and two classes of hose assemblies used for measured fuel dispensing, including oxygenated fuels (up

24、 to a maximum of 15 % oxygenated compounds).The assemblies are intended for use at ambient temperatures between 30 C and +55 C for normal temperature class and 40 C and +55 C for low temperature class at a working pressure up to and including 16 bar (1,6 MPa).NOTE 1 bar = 0,1 MPa.2 Normative referen
