BS EN 13201-4:2015EN 13201-4:2015 (E) 6 Introduction The purpose of Part 4 of this European Standard is to: a) establish conventions and procedur
30、es for the characterization based on measurements of road lighting installations considering the photometric quality parameters, i.e. the set of quantities that characterize a lighting class, specified in Part 2; b) give advice on the use and selection of luminance meters and illuminance meters for
31、this particular application; c) specify measurement requirements according to the aims of the measurement and expected accuracy; d) establish conventions for evaluating the measurement uncertainty of involved parameters; e) give information on the application of tolerance analysis in the design of t
32、he lighting installation. A non-exhaustive list of possible measurement aims is: f) verification of compliance with standard requirements; g) verification of compliance with design expectations; h) road lighting installation monitoring, e.g. for maintenance purposes; i) road lighting installation co
33、ntrol, e.g. for optimizing energy saving; j) investigation of discrepancies between real lighting conditions and design expectations. The conventions for observer position and location of measurement points are those adopted in EN 13201-3. However, relaxation from these is permitted especially where
34、 the measurements are used for monitoring the performance of a road lighting installation, to control its performances or other purposes or when different conditions are specified in the road lighting installation design. Conditions, which can lead to inaccuracies, are identified and precautions are
35、 given to minimize and quantify these. This standard should be used to write measurement procedures for the characterization of road lighting installations. Criteria for deciding when measurements should be done, on the purpose of measurements and on how the measurement results shall be used fall ou
36、tside the scope of this standard. BS EN 13201-4:2015EN 13201-4:2015 (E) 7 1 Scope This European Standard specifies measurement conditions and procedures for measuring the photometric quality parameters of road lighting installations, i.e. the quantities that quantify their performances in accordance
37、 with EN 13201-2 lighting classes. Parameters used for quantifying the energy performance of road lighting installations are not considered. A methodology to evaluate the road lighting performances considering tolerances in the design parameters is described in the informative Annex A. 2 Normative r
