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 nongovernmental, 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, 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, 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
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.
For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment,
as well as information about ISO’s adherence to the World Trade Organization (WTO) principles in the
Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.
The committee responsible for this document is ISO/TC 45, Rubber and rubber products, Subcommittee
SC 1, Rubber and plastics hoses and hose assemblies.
This second edition cancels and replaces the first edition (ISO 11759:1999), which has been technically
revised with the following changes:
— Clause 2: ISO 1746 and ISO 4672 are deleted, and replaced with ISO 106191 and ISO 106192 and
inclusion of ISO 4671;
— Clause 4, Clause 5 and Table 4, addition of Type 3 for conductive hoses;
— Annex B on test frequency and Annex C on production test were added.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 11759:2016(E)
Rubber hoses and hose assemblies for dispensing liquefied
petroleum gases (LPGs) — Specification
WARNING — Persons using this document should be familiar with normal laboratory practice.
This document 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 safety and health practices and to
ensure compliance with any national regulatory conditions.
1 Scope
This document specifies the requirements for flexible rubber hoses and hose assemblies used for the
transfer of metered quantities of liquefied petroleum gases (LPGs) from dispensing equipment to motor
vehicles.
The hoses and hose assemblies specified in this document are intended for use “wet”, i.e. permanently
filled with liquid, in the temperature range from –40 °C to +60 °C.
The maximum working pressure is 2 MPa (20 bar).
