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, 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. 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. www.iso.org/patents

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT), see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 188, Small craft.
This third edition cancels and replaces the second edition (ISO 10239:2008), which has been technically
revised. The major technical changes include:
— suitable user and manufacturer checks of the LPG system tightness;
— specifying a suitable hose material;
— describing the information to be provided in the owner’s manual;
— clarification on LPG powered fuel cells included or excluded from standard.

4.3 All LPG appliances installed on a single LPG system shall be designed for use at the same operating
pressure and the same LPG type, e.g. propane, butane, or a mixture of the two. The operating pressure
shall be clearly labelled in the vicinity of the cylinder shut-off valve.
The cylinder(s) selected and other supply equipment shall be of sufficient capacity to ensure safe and
satisfactory operation of all appliances simultaneously. The cylinder locker or cylinder housing shall be
capable of accommodating the capacity of cylinders needed.
4.4 Where an additional LPG system is installed:
— there shall be no connection between each of the LPG supplies;
— the cylinder(s) for each gas supply may be installed in the same cylinder locker or cylinder housing.
If an additional cylinder locker or cylinder housing is used, there shall be a warning sign inside each
cylinder locker or cylinder housing which indicates that there is an additional LPG supply
Inside the cylinder locker or cylinder housing it shall be clearly indicated which appliances are supplied
by each LPG supply. This shall also be stated in the owner’s manual.
4.5 Each LPG system shall be fitted with simple means to test the LPG system for leakage before use of
any appliances (e.g. a pressure gauge, bubble leak tester).
Where a bubble leak detector is fitted in the LPG system, it shall be securely mounted in the low pressure
side of the LPG system and in the cylinder housing or cylinder locker.
If pressure gauges are used, they shall read the cylinder pressure side of the pressure regulation device.
The gauge scale shall have a pressure range from 0 kPa to a maximum of between 1 000 kPa and
1 600 kPa to be able to show pressure drops during the LPG system check (see C.3).
5 Pressure regulation device
5.1 Each LPG system shall be equipped with, or have provision for the installation of, a pressure
regulation device (see 3.11). This device shall be designed to provide a defined operating pressure suitable
for the consuming appliances, but not more than 5 kPa. A label indicating the operating pressure of the
LPG appliances installed shall be affixed in the vicinity of the LPG cylinder locker or cylinder housing.
5.2 The LPG pressure regulation device shall have an overpressure unit to prevent uncontrolled
pressure increase in the low pressure side to a value above 15 kPa. Any LPG discharge of the unit shall be
inside the cylinder locker or housing, or shall be separately vented outside the craft. The unit may be a
pressure relief governor, a pressure relief valve or an automatic safety shut off valve.
5.3 The operating pressure shall be marked on the pressure regulation device.
5.4 Pressure regulation devices with external manual output pressure adjustment shall not be fitted.
5.5 The pressure regulation device shall be located within the cylinder locker or housing.
5.6 If not rigidly connected to, and supported by, the cylinder connection, the pressure regulation device
shall be separately secured within the cylinder locker or cylinder housing to protect it from damage and
exposure to dirt and water.
It shall be mounted above the cylinder valve so that the flow of LPG from the cylinder valve is always in
a rise to the pressure regulation device.

6 LPG supply line
6.1 General
6.1.1 The LPG supply line shall be either solid piping in accordance with 6.2, except for short hose
connections to the pressure regulation device or to stoves, or continuous hose in accordance with 6.3.
The layout of the supply line shall be such that the length of piping and hoses is as short as possible.
6.1.2 Hoses shall be used to connect
— gimballed stoves to their LPG supply,
— supply piping to the pressure regulation device (either high or low pressure side of the system).
The hose and its connections to the pressure regulation device shall be within the cylinder locker or
cylinder housing.
6.1.3 Piping and hose shall be sized so that any pressure drop due to pipe resistance does not reduce
the operating pressure at any appliance below that required by the appliance manufacturer when all
appliances are operating simultaneously. See Annex A.
6.2 Piping
6.2.1 Only solid drawn copper or drawn stainless steel piping shall be used for rigid supply lines.
Attention should be given to galvanic compatibility when connecting different materials.
Wall thickness for piping shall be equal or greater than 0,6 mm for piping up to 12 mm outside diameter
and a minimum of 0,9 mm for piping with an outside diameter greater than 12 mm. Semi-rigid, pliable
