IEC 60810-2003 pdf – Lamps for road vehicles – Performance requirements.
1 Scope This International Standard is applicable to replaceable lamps (filament lamps and discharge lamps) to be used in headlamps, fog-lamps and signalling lamps for road vehicles. It is especially applicable to those lamps which are listed in IEC 60809. However, the standard may also be used for other lamps falling under the scope of this standard, as well as for future developments, e.g. such where the light is produced by light emitting diodes (LED). It specifies requirements and test methods for the measurement of performance charac- teristics such as lamp life, lumen maintenance, torsion strength, glass bulb strength and resistance to vibration and shock. Moreover, information on temperature limits, maximum lamp outlines and maximum tolerable voltage surges is given for the guidance of lighting and electrical equipment design. For some of the requirements given in this standard, reference is made to data given in tables. For lamps not listed in such tables, the relevant data are supplied by the lamp manufacturer or responsible vendor. The performance requirements are additional to the basic requirements specified in IEC 60809. They are, however, not intended to be used by authorities for legal type-approval purposes. NOTE In the various vocabularies and standards, different terms are used for “incandescent lamp” (IEV 845-07-04) and “discharge lamp” (IEV 845-07-17). In this standard, “filament lamp” and “discharge lamp” are used. However, where only “lamp” is written both types are meant, unless the context clearly shows that it applies to one type only. 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.

3 Terms and definitions For the purpose of this document, the following definitions apply, in addition to the definitions in IEC 60050(845) and IEC 60809. 3.1 life total time (expressed in hours) during which a lamp has been operated before it becomes useless. For filament lamps, it is considered to be so according to one of the following criteria: a) the end of life is the time when the filament fails; b) the life of a dual-filament lamp is the time until either filament fails, if the lamp is tested in a switching cycle involving alternative operation of both filaments 3.2 characteristic life T constant of the Weibull distribution indicating the time up to which 63,2 % of a number of tested lamps of the same type have ended their individual lives 3.3 life B3 constant of the Weibull distribution indicating the time during which 3 % of a number of the tested lamps of the same type have reached the end of their individual lives 3.4 lumen maintenance ratio of the luminous flux of a lamp at a given time in its life to its initial luminous flux, the lamp being operated under specific conditions 3.5 initial luminous flux luminous flux of a lamp measured after the ageing specified in Annex C of IEC 60809 for filament lamps or in Annex D of this standard for discharge lamps 3.6 rated value value of a characteristic specified for operation of a lamp at test voltage and/or other specified conditions 3.7 pinch temperature limit maximum admissible pinch temperature to ensure satisfactory lamp performance in service 3.8 solder temperature limit maximum admissible solder temperature to ensure satisfactory lamp performance in service 3.9 maximum lamp outline contour limiting the space to be reserved for the lamp in the relevant equipment
4.5 Maintien du flux lumineux Le maintien du flux ne doit pas être inférieur à la valeur assignée donnée dans le Tableau 4. Cette valeur est basée sur un niveau de non-conformité de 10 %. 4.6 Résistance aux vibrations et aux chocs Dans le cas où la durée pratique est influencée par des vibrations ou des chocs, les méthodes d’essai et procédures décrites dans l’Annexe B doivent être utilisées afin d’évaluer la performance. Les lampes à filament sont considérées comme ayant entièrement satisfait à l’essai de vibrations aléatoires à large bande ou à bande étroite, tel qu’il est décrit à l’Annexe B, si elles continuent à fonctionner pendant et après l’essai. Le nombre de lampes à filament défaillantes lors de l’un des essais ne doit pas dépasser les valeurs du Tableau 2 (valeurs basées sur un NQA de 4 %).
