This Eur
19、opean Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2016 and conflicting national standards shall be withdrawn at the latest by June 2016. Attention is drawn to the possibility that some of the elements
20、of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13201-3:2003. In comparison with EN 13201-3:2003, three significant changes were made: in the veiling luminance calculatio
21、n, Lv, there is no more test about the contribution of at least 2 % of the next luminaire in the row to end the calculation before reaching a distance of 500 m (this is to avoid ambiguous interpretations that can produce different results from different software); the default option is about 500 m,
22、but there is an alternative to retain only the luminaires of a shorter installation. This last case should be clearly mentioned in the lighting design by the number of luminaires involved in calculation of fTI; there is a new formula for calculating veiling luminance Lv, for a wider range of values.
23、 Thus the case where luminaires could be very near to the axis of vision of the observer: 0,1 20 lx Number of decimal places 2 2 2 0 2 2 1 0 5 Photometric data 5.1 General Photometric data for the light distribution of the luminaires used in the lighting installation are needed for calculating the l
24、ighting quality characteristics in this standard. These data are in the form of an intensity table (I-table) which gives the distribution of luminous intensity emitted by the luminaire in all relevant directions. When luminance calculations are to be made, photometric data for the light reflecting p
