IEC 60983-2005 pdf – Lampes miniatures Miniature lamps.
1.1 Scope This International Standard specifies requirements for miniature halogen and non-halogen lamps with a nominal voltage up to 30 V and a nominal wattage up to 25 W. It covers: – lamps to be used in road vehicles not subject to regulation and which therefore are not included in IEC 60809 (section 2); – lamps for electric torches (section 3); – lamps for miners’ caplights (section 4). Aircraft lamps are standardized in IEC 60434. This standard specifies dimensional, electrical and photometric requirements as well as requirements concerning life and mechanical strength. NOTE Requirements are for production lamps. Individual lamps might not be completely within these requirements. Where conditions of compliance are required, they are specified in the relevant section. For some of the requirements given in this standard, reference is made to “the relevant lamp data sheet”. For some lamps these data sheets are contained in this standard. For other lamps, falling under the scope of this standard, the relevant data are supplied by the lamp manufacturer or responsible vendor. This Standard may also be used for future developments, e.g. where the light is produced by light emitting diodes (LED). 1.2 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. IEC 60050-845:1987, International Electrotechnical Vocabulary (IEV) – Chapter 845: Lighting IEC 60061-1:1969, Lamp caps and holders together with gauges for the control of interchangeability and safety – Part 1: Lamp caps IEC 60434:1973, Aircraft electrical filament lamps Amendment No. 1 (1981), Amendment No. 2 (1984) IEC 60809:1985, Lamps for road vehicles – Dimensional, electrical and luminous requirements Amendment No. 1 (1987), Amendment No. 2 (1989), Amendment No. 3 (1992)
1.3 Definitions For the purposes of this International Standard, the following definitions apply. 1.3.1 lamp (incandescent): Source made in order to produce light by means of an element heated to incandescence by the passage of an electric current. [A combination of IEV 845-07-03 and IEV 845-07-04.] 1.3.2 tungsten halogen lamp: Gas-filled lamp containing halogens or halogen compounds, the filament being tungsten. [IEV 845-07-10] 1.3.3 nominal voltage: Voltage used to designate a lamp. 1.3.4 nominal wattage: Wattage used to designate a lamp. 1.3.5 test voltage: Voltage for which some characteristics of a lamp are specified and at which they shall be tested. 1.3.6 rated value: Quantity value for specified operating conditions of a component, device or equipment assigned by a manufacturer or specified in a product standard. 1.3.7 tolerance: Allowable variation from a specified value, generally expressed in per cent of this value. 1.3.8 limit value: Lowest and/or highest value for characteristics a lamp has to comply with when operated under test conditions. 1.3.9 initial readings: Photometric and electrical values measured at the end of the ageing period. 1.3.10 ageing period: Period of time for which an unused lamp is operated in order to stabilize its photometric and electrical characteristics. 1.3.11 life: The total time for which a lamp has been operated before it becomes useless, or is considered to be so, according to specific criteria. [IEV 845-07-61] NOTE – Lamp life is normally expressed in hours.
1.6 Data sheets 1.6.1 Numbering system for data sheets and lamps The first number represents the number of this standard “60983” followed by the letters “IEC”. The second number consists of a four-digit group. The first digit represents the relevant section of this standard, the second and third digits represent the sheet identifier and the fourth digit represents the lamp type except zero which is reserved as part of the sheet identifier. The third number represents the edition of the data sheet page. In cases where a data sheet has more than one page, it is possible for the pages to have different edition numbers with the data sheet numbering remaining the same. 1.7 Recommended instructions for the use of halogen lamps It is recommended that the following points are included in any instructions for use if supplied with tungsten halogen lamps covered by this standard: – tungsten halogen lamps operate at high bulb temperatures and care should be taken to avoid touching the bulb under any circumstances; – if lamps with a quartz bulb are touched, they should be cleaned before use with a lint-free cloth moistened with spirit (alcohol);
