18、ith regard to energy labelling of household lamps. A method of classification of lamps according to energy efficiency is given in the Directive and is not a part of this standard. This standard specifies the test conditions and method of measurement of luminous flux, lamp wattage and lamp life as gi

19、ven on a label on the lamp packaging, together with a procedure for verification of the declared values. Only those parameters that are specific to the above mentioned Directive are included in this standard. All other parameters are included in the relevant lamp performance standards. Lamps covered

20、 by this standard are: mains voltage tungsten filament lamps; mains voltage tungsten halogen lamps; self-ballasted lamps; double-capped fluorescent lamps; single-capped fluorescent lamps. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other

21、publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or re

25、pecified test conditions (life to 50 % lamp failure). For tungsten filament lamps average life is defined as the mean value of the truncated life distribution as specified in EN 60064. 3.2 rated average life the average life declared by the manufacturer or responsible vendor NOTE The rated average l

26、ife is not necessarily the average of all individual lamp lives. It may only be used for comparison, since operating conditions in practice may differ from the specified conditions used in life testing. 3.3 lamp failure failure of a lamp to light up, or to meet the starting requirements of the relev

27、ant lamp standard or to remain alight 4 Test conditions Lamps shall be tested in accordance with the relevant clauses of the standards listed below. For tungsten filament lamps: EN 60064. For tungsten halogen lamps: EN 60064 (the accelerated life test does not apply). For self-ballasted lamps: EN 60

28、969. For double-capped fluorescent lamps: EN 60081. For single-capped fluorescent lamps: EN 60901. For the measurement of the luminous flux CIE 84 also applies. 5 Verification The minimum sample size shall be twenty lamps. The sample shall be representative of a manufacturers production. This can be

29、 achieved by randomly selecting lamps from at least four different points of sale. The results of the tests shall comply with the requirements given in 6.1 to 6.3. If the test results do not comply with these requirements, the manufacturers test records shall be requested.Page 4 EN 50285:1999 BSI 08

30、-1999 6 Requirements 6.1 Luminous flux The average value of the initial readings of the luminous flux of the sample shall be not less than the percentage of the declared value, given in Table 1. 6.2 Lamp wattage The average value of the initial readings of the lamp wattage of the sample shall not ex

31、ceed the percentage of the declared value, given in Table 1. 6.3 Lamp life For tungsten filament lamps the average life of the sample , i.e. the mean value of the truncated life distribution as defined in EN 60064, shall be not less than 90 % of the declared value. For other lamp types the average l

32、ife of the sample, i.e. life to 50 % lamp failure, shall be not less than 90 % of the declared value.
