25、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

26、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 docum

42、C to +60 C. 4.2 LPG systems shall be of the vapour withdrawal type, i.e. fuel released only under gas phase conditions. 4.3 All LPG appliances installed on the craft shall be designed for use at the same working pressure. 4.4 Each system shall be fitted with a pressure gauge. The gauge shall read th

43、e 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. Th

44、e 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.

With appliance valves closed, open the cylinder valve. Close cylinder valve. Allow indicated gauge press

46、ure 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,

47、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

48、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
