g) Lamps shall be easily replaceable, if applicable.
h) Luminaires used in hazardous areas shall comply with the relevant part of IEC 60079.
Hazardous spaces of ships can be e. g. paint stores and battery rooms where, dependingon ventilation arrangement,luminaires may be required to comply with relevant parts ofIEC 6o079.
i) Special consideration shall be given to the design of luminaires for installation in areaswhere the ambient temperature is ≥ +45 C or s -25°c.
4.2.2Materials
With respect to durability and resistance to environmental conditions,luminaires and lightingaccessories shall meet the requirements specified in Clause 7 of this standard.The materialsshall additionally comply with the following requirements.
a) The materials used for the luminaires and their mounting parts shall be non-toxic andflame retardant.
b) Parts which require surface protection shall be designed in a way that functional andoperational safety is ensured.
c) Non-metallic external parts of luminaires,enclosures and attachments shall withstand theexposure to Uv and visible radiation and shall be halogen-free.
d) External parts and housings of luminaires intended for outdoor installation shall be of metal.
e) lf coating of the luminaires or parts or enclosures is necessary to achieve corrosion
resistance, it shall be in accordance with EN 12206-1 in case of aluminium and aluminiumalloy or in accordance with EN 13438 in case of steel.
Tests for requirements a) and c) are stated in 7.2.5.
4.3Electrical requirements
4.3.1Electrical safety
Electrical safety shall be ensured by compliance with the tests specified in 7.3.4.3.2Luminaires for use on lT power distribution systems
Luminaires intended to be operated on on-board power supply systems shall be designed insuch a way that they may be operated on a power distribution system which is not earthed(IT-system).Switches in luminaires intended for use on lT-systems shall be bipolar. If fusesare included in the luminaire, they shall be installed in each line conductor.
4.3.3Electromagnetic compatibility
In general, the requirements stated in lEC 60533 shall be met. Luminaires specified for use inthe bridge area and radio room shall meet the requirements stated in IEC 60945.
4.4lumination technology
Photometric data in accordance with EN 13032-1 shall be provided by the manufacturer inelectronic format suitable for further electronic design and calculation.
4.5 Environmental conditions Luminaires shall be so designed as to withstand the applicable environmental influences during storage and ship’s operation. The tests shall be carried out in accordance with 7.2. For environmental tests, the recommendations of IEC/TR 60721 -4-6 should be taken into account.
4.6 Special requirements on discharge lamp luminaires On discharge lamp luminaires all ballasts, capacitors and other auxiliaries mounted separately from the luminaires shall be enclosed in an earthed metal casing. Discharge lamps should be used only in fixed luminaires. Discharge lamp installations shall be durably marked with the warning symbol given in IEC 60598-1 . The marking shall be of a suitable size. Transformers should be located as close as possible to the luminaire installation but no more than 1 00 m apart from the luminaire’s installation.
4.7 Component parts Component parts of luminaires shall comply with their relevant standards and shall be in accordance with the requirements stated in 4.2 and the requirements stated in the publications given in Table 1 .
