IEC 62035-2014 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. This standard only concerns safety criteria and does not take into account performance. The performance standards IEC 601 88, IEC 601 92, IEC 60662, IEC 61 1 67 and IEC 61 549 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 1 1 0 % of rated supply voltage and when operated with a ballast complying with IEC 61 347-2-9 and IEC 60923, with a starting device complying with IEC 61 347-2-1 and IEC 60927, and in a luminaire complying with IEC 60598-1 . 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

3 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 60050-845 and IEC TR 62778, as well as the following apply. 3.1 HID lamp high intensity discharge lamp electric discharge lamp in which the light-producing arc is stabilised by wall temperature and the arc has a bulb wall loading in excess of 3 W/cm 2 Note 1 to entry: HID lamps include groups of lamps known as high-pressure mercury, metal halide and high- pressure sodium lamps. [SOURCE: IEC 60050-845:1 987, 845.07.1 9] 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 1 00 kPa Note 1 to entry: 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. [SOURCE: IEC 60050-845:1 987, 845.07.20] 3.3 blended lamp self-ballasted mercury lamp, US lamp containing in the same bulb certain elements of a mercury vapour lamp and an incandescent lamp filament connected in series Note 1 to entry: The bulb may be diffusing or coated with phosphors. [SOURCE: IEC 60050-845:1 987, 845.07.21 , modified — The words “certain elements of” are added.]] 3.4 high pressure sodium vapour lamp high-intensity discharge lamp in which the light is produced mainly by radiation from sodium vapour operating at a partial pressure of the order of 1 0 kPa Note 1 to entry: The term covers lamps with clear or diffusing bulb.
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 Pa to 1 ,5 Pa [SOURCE: IEC 60050-845:1 987, 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 1 to entry: The definition covers clear and coated lamps. [SOURCE: IEC 60050-845:1 987, 845.07.25, modified — The words “radiation” and “metal halides” are added.] 3.7 nominal power approximate quantity value of lamp power used to designate or identify a lamp 3.8 ultraviolet hazard efficacy of luminous radiation effective power of the UV radiation of a lamp related to its luminous flux Note 1 to entry: Ultraviolet hazard efficacy of luminous radiation is expressed in mW/klm Note 2 to entry: The effective power of the UV radiation is obtained by weighting the spectral power distribution of the lamp with the UV hazard function SUV(λ). Information about the relevant UV hazard function is given in IEC 62471 . 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 [SOURCE: IEC 60081 :1 997, 1 .4.1 0] 3.1 0 type test sample sample consisting of one or more similar units submitted by the manufacturer or responsible vendor for the purpose of the type test
