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 3.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
Annexes A to G form a normative part of this International Standard ISO 15370 which was prepared by Technical
Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 1, Lifesaving and fire protection.

4 Performance requirements
4.1 General
4.1.1 The competent authority shall ensure that LLL systems and their components meet the requirements set
out in this International Standard, as verified through the presentation of relevant certificates issued by recognized
laboratories.
4.1.2 Combinations of PL and EP systems may be permitted. However, only one system shall be applied for
each deck or stairway enclosure unless the deck or stairway enclosure is separated by normally closed doors. In
addition, signs and markings made of PL materials may be used with EP systems.
4.1.3 The supplementary emergency lighting for ro-ro passenger ships required by Regulation II-1/42-1 of the
1974 SOLAS Convention, as amended, may be accepted to form partly or wholly the LLL system, provided that
such a system complies with the requirements of this International Standard.
4.1.4 Interruption of the LLL system due to constructional practicalities (corridors, cabin doors, etc.) shall not
exceed 2 m.
4.1.5 The LLL system shall function at all times for at least 60 min after its activation.
4.1.6 LLL products shall not contain radioactive materials unless such materials are designated “sealed
radioactive materials” tested in accordance with ISO 2919. However, materials containing radioactive
radionuclides, as shown in ISO 2919:1999, annex A, are considered as sealed radioactive materials which should
be tested in accordance with ISO 2919.
4.1.7 LLL systems shall not release toxic materials under normal conditions.
4.2 Photoluminescent systems
2
4.2.1 Photoluminescent materials shall provide a luminance of at least 15 mcd/m measured 10 min after the
removal of all external illuminating sources. The system shall continue to provide luminance values greater than
2
2mcd/m for 60 min. The light level shall be measured at the surface of the materials. The minimum level of
ambient light necessary to charge the PL material to meet the required luminance values and the spectrum
emission of the light adopted during the test contained in annexes A through C, shall be verified and recorded.
4.2.2 Except where noted, PL strips should have a width of 75 mm or greater. Photoluminescent strips having a
width less than 75 mm shall only be used if the luminance is increased to compensate for the reduced width in
accordance with Table D.1 annex D.
4.2.3 PL materials shall be flame-retardant materials in accordance with IEC 60092-101.
4.2.4 PL materials shall be tested in accordance with annex A.

ISO 15370:2001(E)
4.3 Electrically powered systems
4.3.1 Electrically powered systems shall be connected to the emergency switchboard as required by Regulation
II-1/42 of the 1974 SOLAS Convention, as amended, so as to be powered by the main source of electrical power
under normal circumstances and also by the emergency source(s) of electrical power (as identified by Regulations
II-1/42.3) when the latter is in operation. Alternatively, for passenger ships carrying more than 36 passengers and
built before October 1, 1994, EP systems may be connected to the main lighting system, provided independent
batteries provide a backup of at a least 60 min and are charged from the main lighting system. Performance of the
system while powered by batteries shall meet all the requirements stated herein.
4.3.2 For planar or line sources such as electroluminescent or electrofluorescent panels, or side-emitting fibre
2
optics, the surface of the indicators shall have a minimum luminance of 10 cd/m . The luminous intensity along a
line source shall be uniform, such that the maximum luminance of the source does not exceed the minimum
luminance of the same source by a factor of greater than ten.
4.3.3 Point sources
4.3.3.1 Miniature incandescent lamps shall provide not less than 150 mcd mean spherical intensity with a
spacing of not more than 100 mm between lamps.
4.3.3.2 Sub-miniature incandescent lamps and light-emitting diodes (LEDs) shall have a minimum intensity of
35 mcd at the centre of the appropriate viewing cones. The intensity distribution shall be appropriate to the likely
track directions of approach and viewing. For sources which are required to be viewed from a horizontal position,
(i.e., deck mounted or horizontal bulkhead mounted fittings) the intensity distribution shall be within a 60° cone
having its centre located 30° from the horizontal mounting surface of the point source and in line with the track
direction. For sources which are required to be viewed vertically (i.e., the vertical LLL marking up to the door
handles) the intensity distribution shall be within a 60° cone having its centre located perpendicular to the mounting
surface of the point source. Spacing between sources shall be not more than 300 mm. See annex E, Figures E.1
and E.2.
4.3.4 The power-supply arrangements to the LLL system shall be arranged so that a single break in the supply
cabling does not result in the system becoming ineffective.
NOTE This requirement can be achieved by using at least two battery power supplies in each single main vertical fire zone
or by using fire-resistant cables, in accordance with IEC 60331, from the emergency switchboard to the input of the LLL system.
4.3.5 EP systems shall meet the relevant requirements for emergency luminaires in accordance with
IEC 60598-2-22 when tested at a reference temperature of 40 °C.
4.3.6 EP systems shall meet the requirements for vibration and electromagnetic interference in accordance with
IEC 60945.
4.3.7 EP systems shall provide a minimum degree of ingress protection of at least IP 55 in accordance with
IEC 60529.
4.3.8 EP materials shall be flame retardant in accordance with IEC 60092-101.
4.3.9 Entire systems, including those that are automatically activated or continuously operating, shall be capable
of being manually activated by a single action from the continuously manned central control station. Deactivation of
the system shall only be possible from the continuously manned central control station.
4.3.10 EP materials shall be tested in accordance with annex F.

� installation plan, which should include the wiring layout and contain examples of the details of LLL signs,
markings, and arrangements;

6 Installation on board
6.1 General
6.1.1 Positioning of the LLL system and signs shall be arranged to enable persons to readily identify all escape
routes and exits. However, LLL should not be installed in public spaces. In addition, to prevent escaping persons
from having to cross
