BS IEC 60092-306 pdf download Electrical installations in ships — Part 306: Equipment – Luminaires and lighting accessories
4.1 General Luminaires shall comply with the requirements of IEC 60598-1 and with the additional requirements included in this standard. Luminaires in accordance with this standard shall be suitable for continuous operation.
4.2 Mechanical requirements
4.2.1 Design The design of luminaires shall comply with the requirements of IEC 60092-1 01 and with the following additional requirements.
a) Luminaires shall have sufficient mechanical resistance for the intended use. The mechanical properties shall be in accordance with intended purpose and installation location. To meet the requirement of mechanical resistance, the equipment shall withstand the respective shock and vibration conditions given in the Tables 3 and 4.
b) Luminaires shall be designed, dimensioned and equipped with mounting devices in such a way that they will present no hazard to persons, in particular during operation and maintenance work.
c) The minimum degrees of IP protection in accordance with IEC 60529 required in the different environmental conditions related to locations are given in IEC 60092-201 :1 994, Table 5.
d) Luminaires shall be so constructed as to provide for adequate dissipation of heat from lamps and related components. The temperature rise of terminals for connection of supply cables shall not exceed 40 °C. Insulation material of internal parts shall be of a temperature class which corresponds to the maximum temperature within the luminaires.
e) The temperature of surface parts which can be touched during operation shall not exceed 60 °C. If this is not possible, e. g. in case of floodlights or discharge lamps, these luminaires shall be mounted in a way that they cannot be reached without the use of additional facilities.
f) Luminaires shall be constructed in such a way that they can be easily cleaned inside, if applicable.
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, depending on ventilation arrangement, luminaires may be required to comply with relevant parts of IEC 60079.
i) Special consideration shall be given to the design of luminaires for installation in areas where the ambient temperature is ≥ +45 °C or ≤ –25 °C.
4.2.2 Materials
With respect to durability and resistance to environmental conditions, luminaires and lighting accessories shall meet the requirements specified in Clause 7 of this standard. The materials shall additionally comply with the following requirements.
a) The materials used for the luminaires and their mounting parts shall be non-toxic and flame retardant.
b) Parts which require surface protection shall be designed in a way that functional and operational safety is ensured.
