ISO 10239:2008(E) iv © ISO 2008 – All rights reserved 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. 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. ISO 10239 was prepared by Technical Committee ISO/TC 188, Small craft. This second edition cancels and replaces the first edition (ISO 10239:2000), which has been technically revised. It also incorporates the Technical Corrigendum ISO 10239:2000/Cor.1:2001.

INTERNATIONAL STANDARD ISO 10239:2008(E) © ISO 2008 – All rights reserved 1Small craft — Liquefied petroleum gas (LPG) systems 1 Scope This International Standard covers permanently installed liquefied petroleum gas (LPG) systems and LPG burning appliances on small craft of hull length up to 24 m, except for systems used on LPG-fuelled propulsion engines or LPG-driven generators. This International Standard does not cover appliances with directly attached gas cylinders, such as portable self-contained camping stoves and portable gas lamps. NOTE 1 This International Standard is not intended to regulate technical requirements for LPG cylinders, which are subject to national regulations. NOTE 2 New designs, materials and methods of assembly giving at least equivalent results can be considered to be complying with the requirements of this International Standard when approved by a relevant body. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 2928, Rubber hoses and hose assemblies for liquefied petroleum gas (LPG) in the liquid or gaseous phase and natural gas up to 25 bar (2,5 MPa) — Specification ISO 8846, Small craft — Electrical devices — Protection against ignition of surrounding flammable gases ISO 9094-1, Small craft — Fire protection — Part 1: Craft with a hull length of up to and including 15 m ISO 10133, Small craft — Electrical systems — Extra-low-voltage d.c. installations ISO 10240, Small craft — Owner's manual ISO 13297, Small craft — Electrical systems — Alternating current installations 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 liquefied petroleum gas LPG mixture of light hydrocarbons, gaseous under conditions of normal temperature and pressure, and maintained in the liquid state by increase of pressure or lowering of temperature NOTE 1 The principal components are propane, propene, butanes or butenes. NOTE 2 LPG can be obtained as commercial butane, commercial propane or a mixture of the two.

system consisting of an arrangement of cylinder(s), safety device(s), pressure regulator(s), connection(s), valve(s), piping, tubing, hose, fitting(s) and devices intended to store, supply, monitor or control the flow of fuel gas up to and including the appliance NOTE The cylinders are replacement items and may not be supplied with the LPG system in the craft. 3.6 accessible capable of being reached for inspection, removal or maintenance without removal of a permanent part of the craft structure, with or without the use of tools 3.7 readily accessible capable of being reached quickly and safely for maintenance or effective use under emergency conditions without the use of tools 3.8 unattended appliance appliance intended to function without the constant attention of an operator and which may cycle on and off automatically NOTE Examples of unattended appliances are water heaters, refrigerators and cabin heaters. Stoves, ovens and gas lamps are not considered to be unattended appliances. 3.9 high pressure side part of the LPG supply line directly exposed to pressure at the inlet of a pressure regulator in a liquefied petroleum gas system NOTE 1 Vapour pressure propane at 20 °C = 0,7 MPa1).

The gauge shall read the cylinder pressure side of the pressure regulator. The gauge scale shall have a pressure range from 0 kPa to a minimum of 1 200 kPa and a maximum of 1 400 kPa. NOTE The purpose of the gauge is to provide a convenient, simple means to test the system for leakage before each use of the appliances. The gauge does not provide an indication of liquid LPG remaining in the cylinder, only its vapour pressure, which is a constant at any given temperature.

ISO 10239:2008(E) 4 © ISO 2008 – All rights reserved 4.5 A sign shall be fixed in the vicinity of the cylinder shut off valve, listing the leak test procedure using the pressure gauge, as described below. ⎯ With appliance valves closed, open the cylinder valve. ⎯ Close cylinder valve. Allow indicated gauge pressure to stabilize. ⎯ Observe pressure on gauge for 3 min. ⎯ If pressure remains constant, no leak is present. If pressure falls, a leak exists. Do not use LPG system until leak is repaired. 5 Pressure reduction system 5.1 Each LPG system shall be equipped with, or have provision for the installation of, a pressure regulation system (see 3.11). This system shall be designed to provide a fixed nominal pressure suitable for the consuming appliances, but not more than 0,005 MPa. A label indicating the working pressure of the LPG appliances installed shall be affixed in the vicinity of the LPG cylinder installation. 5.2 The LPG pressure reduction system shall have an overpressure device to prevent uncontrolled pressure increase in the low pressure side to a value below 0,015 MPa. Any gas discharge of the device shall be inside the cylinder locker or housing, or shall be separately vented outside the craft. The device may be a pressure relief governor, a pressure relief valve or an automatic safety shut off valve. 5.3 The nominal pressure shall be indicated on the pressure regulator. 5.4 Pressure regulators with external manual output pressure adjustment shall not be fitted. 5.5 The pressure regulator shall be located within the cylinder locker or housing. 5.6 If not rigidly connected to, and supported by, the cylinder connection, the pressure regulator shall be separately secured within the cylinder locker or cylinder housing to protect it from damage and exposure to dirt and water, and be mounted above the cylinder valve so that the attaching connection to the cylinder valve has a continuous rise to the regulator. 5.7 Pressure regulators shall be made of corrosion-resistant metallic material or have an effective coating, such as paint or plastic, against external corrosion. Fasteners used shall be of corrosion-resistant material or have a corrosion-resistant plating or coating. NOTE Pressure reduction systems in accordance with EN 12864:2001, Annex M, or in accordance with EN 13786 meet the requirements. 6 LPG supply line system 6.1 General 6.1.1 The LPG supply line system shall be either a solid piping system in accordance with 6.2, except for short hose connection to gimballed stoves, or continuous hose in accordance with 6.3. 6.1.2 Hoses shall be used to connect gimballed stoves to their LPG supply, and to connect supply piping to the pressure regulator. The hose and its connections from supply piping to the pressure regulator shall be within the cylinder locker or cylinder housing. 6.1.3 Piping and hose shall be sized so that pressure drop due to pipe resistance does not reduce the nominal pressure at any appliance below that required by the appliance manufacturer when all appliances are operating simultaneously. See Annex A.
