IEC 60968 pdf download.Self-ballasted fluorescent lamps for general lighting services – Safety requirements
1 Scope
This International Standard specifies the safety and interchangeability requirements, together with the test methods and conditions required to show compliance of tubular fluorescent lamps with integrated means for controlling starting and stable operation (self-ballasted fluorescent lamps). These lamps are intended for domestic and similar general lighting purposes, having a rated voltage of 50 V to 250 V, having a rated frequency of 50 Hz or 60Hz and having IEC 60061 -1 compliant caps. For a cap-holder system not specifically mentioned in this standard, the relevant information on safety related tests provided by the manufacturer will apply. The requirements of this standard relate only to type testing. Recommendations for whole product testing or batch testing are given in Annex A. This part of the standard covers photobiological safety according to IEC 62471 and IEC TR 62471 -2. Blue light and infrared hazards are below the level which requires marking.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply: 3.1 self-ballasted lamp unit which cannot be dismantled without being permanently damaged, provided with a lamp cap and incorporating a light source and any additional elements necessary for starting and stable operation of the light source 3.2 nominal value approximate quantity value used to designate or identify a lamp [SOURCE: IEC 60901 :1 997, 1 .4.3] 3.3 rated value quantity value for a characteristic of a lamp for specified operating conditions Note 1 to entry: The value and the conditions are specified in this standard, or assigned by the manufacturer or responsible vendor. [SOURCE: IEC 60901 :1 997, 1 .4.4, modified — The second sentence is moved to a note to entry.] 3.4 cap temperature rise ∆t s surface temperature rise (above ambient) of a standard test lampholder fitted to the lamp’s cap, when measured in accordance with the standard method described in IEC 60360 [SOURCE: IEC 60432-1 :1 999, 1 .3.8 3.5 live part conductive part which may cause an electric shock in normal use 3.6 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 3.7 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 3.8 specific effective radiant UV power effective power of the UV radiation of a lamp related to its luminous flux Note 1 to entry: The specific effective radiant UV power 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 S UV (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 test family lamp groups which are distinguished by common features of materials relevant to the test applied
4 General requirements and general test requirements
4.1 Self-ballasted lamps shall be so designed and constructed that in normal use they function reliably and cause no danger to the user or surroundings. In general, compliance is checked by carrying out all the tests specified. 4.2 All measurements unless otherwise specified in this standard, shall be carried out at rated voltage and frequency and in a draught-proof room. The ambient temperature shall be from 23 °C to 27 °C inclusive and shall not vary by more than 1 °C during the measurements. If lamps are rated for alternative frequencies the test shall be carried out at the most onerous of these. The test voltages are specified in the relevant clauses. 4.3 Self-ballasted lamps are non-repairable, factory sealed units. They shall not be opened for any tests with exemption of 1 3.2. In the case of substantiated doubt based on the inspection of the lamp and the examination of the circuit diagram, and in agreement with the manufacturer or responsible vendor, lamps specially prepared so that a fault condition can be simulated shall be submitted for testing (see Clause 1 3 and Clause 1 5).
