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.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, 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, 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 patent 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 in this document is information given for the convenience of users and does not constitute an endorsement.

The committee responsible for this document is ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Hoses (rubber and plastics).

This fourth edition cancels and replaces the third edition (ISO 2929:2002) which has been revised as specified below.

This minor revision of the third edition (ISO 2929:2002) was required to bring this International Standard up to date. The following changes were made.

• In Clause 2 (Normative references), reference to ISO 1746 (bending tests) has been replaced by ISO 10619-1 as ISO 1746 has been withdrawn and replaced by ISO 10619-1.
• The same editorial changes have been made in the text of the standard wherever necessary and the note in Clause 6 (referring to inside diameters above 80 mm) has been deleted.
• The term “type testing” has been added to Clause 10 and Annex E as this is now the normative term for this type of test (according to ISO 8330).

1 Scope

This International Standard specifies the requirements for two groups of rubber hoses and rubber hose assemblies for loading and discharge of liquid hydrocarbon fuels with a maximum working pressure of 10 bar (1,0 MPa).

Both groups of hoses are designed for:

• a) use with hydrocarbon fuels having an aromatic-hydrocarbon content not exceeding 50 % by volume and containing up to 15 % of oxygenated compounds;
• b) operation within the temperature range of − 30 °C to + 70 °C, undamaged by climatic conditions of − 50 °C to + 70 °C when stored in static conditions.

This International Standard is not applicable to hoses and hose assemblies for LPG systems, aviation fuel systems, fuel station systems or marine applications.
