IEC 62035-2003 pdf – Discharge lamps (excluding fluorescent lamps) – Safety specifications.
1 Scope This International Standard specifies the safety requirements for discharge lamps (excluding fluorescent lamps) for general lighting purposes. This International Standard is applicable to low-pressure sodium vapour lamps and to high- intensity discharge (HID) lamps, i.e. high-pressure mercury vapour lamps (including blended lamps), high-pressure sodium vapour lamps and metal halide lamps. It applies to single- and double-capped lamps, having caps as listed in annex A. NOTE This standard only concerns safety criteria and does not take into account performance. The performance standards IEC 60188, IEC 60192, IEC 60662, IEC 61167 and IEC 61549 should be referred to for such characteristics. It may be expected that lamps which comply with this standard will operate safely at supply voltages between 90 % and 110 % of rated supply voltage and when operated with a ballast complying with IEC 60922 and IEC 60923, with a starting device complying with IEC 60926 and IEC 60927, and in a luminaire complying with IEC 60598-1. 2 Normative references Les documents de référence suivants sont indispensables pour l’application du présent document.

[IEV 845-07-19] 3.2 high-pressure mercury (vapour) lamp high-intensity discharge lamp in which the major portion of the light is produced, directly or indirectly, by radiation from mercury operating at a partial pressure in excess of 100 kilo- pascals NOTE This term covers clear, phosphor coated (mercury fluorescent) and blended lamps. In a fluorescent mercury discharge lamp, the light is produced partly by the mercury vapour and partly by the layer of phosphors excited by the ultraviolet radiation of the discharge. [IEV 845-07-20] 3.3 blended lamp; self-ballasted mercury lamp (USA) lamp containing in the same bulb certain elements of a mercury vapour lamp and an incandescent lamp filament connected in series NOTE The bulb may be diffusing or coated with phosphors. [IEV 845-07-21, modified]
3.5 low-pressure sodium (vapour) lamp discharge lamp in which the light is produced by radiation from sodium vapour operating at a partial pressure of 0,1 to 1,5 pascal [IEV 845-07-24] 3.6 metal halide lamp high-intensity discharge lamp in which the major portion of the light is produced by radiation from a mixture of metallic vapour, metal halides and the products of the dissociation of metal halides NOTE The definition covers clear and coated lamps. [IEV 845-07-25, modified] 3.7 nominal wattage approximate quantity value of lamp wattage used to designate or identify a lamp 3.8 specific effective radiant UV power effective power of the UV radiation of a lamp related to its luminous flux Unit: mW/klm NOTE The effective power of the UV radiation is obtained by weighting the spectral power distribution of the lamp with the UV hazard function S UV (λ). Information about the relevant UV hazard function is given in CIE S009. It only relates to possible hazards regarding UV exposure of human beings. It does not deal with the possible influence of optical radiation on materials, like mechanical damage or discoloration. 3.9 type test test or series of tests made on a type test sample for the purpose of checking compliance of the design of a given product with the requirements of the relevant standard
