Introduction The purpose of this part of this European standard is to establish conventions and procedures for lighting measurements of road lighting installations, and to give advice on the us
21、e and selection of luminance meters and illuminance meters. The conventions for observer position and location of measurement points are those adopted in EN 13201-3. However, relaxation from these is permitted where the measurements are used for monitoring the performance of an installation or other
22、 purposes. Conditions which may lead to inaccuracies are identified and precautions are given to minimize these. A format for the presentation of the measurements is suggested. EN 13201-4:2003 (E) 4 1 Scope This part of this European Standard specifies the procedures for making photometric and relat
23、ed measurements of road lighting installations. Examples are given of the form of the test report. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text,
24、 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 revision. For undated references the latest edition of the publication referred to applies
25、 (including amendments). EN 13201-3, Road lighting Part 3: Calculation of performance. 3 Photometric measurements The procedures adopted should be suited to the purpose of the measurements. Where the measurements are required for comparison with calculated values then the utmost stringency will be r
26、equired to ensure that a valid comparison can be made. Where the measurements are required for monitoring the state of an installation then it is possible that a more limited set of measurements at widely spaced locations will suffice. The main essential in this case is that the measurements are car
27、ried out in the same way each time monitoring is carried out. In other cases spot checks may be sufficient. 4 Measurement conditions 4.1 Stabilization after switch-on Discharge lamps require a period of time for their light output to stabilize. llluminance measurements at the same location or locati
28、ons shall be taken at regular time intervals to ensure that stability has been reached, before definitive light measurements of the installation are made. To ensure that stability is maintained during the period of measurement, monitoring readings shall be taken (see A.10). 4.2 Climatic conditions T
29、he climatic conditions should be such as not to affect the measurements significantly, unless this is intended. High or low temperatures may affect the light output of thermally sensitive lamps or the accuracy of the light measuring instruments. Condensation of moisture on light transmitting surface
30、s of measuring instruments or on their electric circuits may affect their accuracy. High wind speeds may make the luminaires oscillate or make the measuring instruments vibrate. They may also lower the temperature of thermally sensitive lamps thereby affecting their light output. Even a slight dampn
31、ess of the road surface may significantly affect the luminance of the road surface. The light transmission of the atmosphere will affect the light reaching the surface to be measured, and in the case of luminance measurements the light reaching the luminance meter from the surface to be measured. EN
32、 13201-4:2003 (E) 5 4.3 Extraneous light and obstruction of light When measurements are intended to record the lighting performance of the road lighting installation only, direct or reflected light from the surrounds should be prevented or accounted for. Action taken to do this should be recorded in
33、 the report on the measurements (see A.7). NOTELight from the surrounds can include light from shop windows, advertising signs, road signals, lights on vehicles, other lighting installations, sky glow, reflections from snow at the road side, etc. This lighting can sometimes be prevented, masked or s
34、witched off, or sometimes a correction can be made which is based on separate measurements taken with the road lighting installation switched off. A correction for sky glow depends on the cloudiness not being variable. When measurements are intended to record the unobstructed light from the installa
35、tion, measurement areas should be selected which are free of obstructions that may produce shadows. These may include trees, parked cars, or road furniture. The presence of obstructions should be recorded in the report on the measurements (see A.7). 4.4 Measurements taken from a moving vehicle The l
36、ight performance of an installation can be measured from a moving vehicle. The main differences between dynamic and static measurements are: ? the number of measurement points is greater in the case of dynamic measurements: ? the requirements in EN 13201-3 for observer position and location of grid
37、points may be more difficult or impossible to meet in the case of dynamic measurements. To produce useful and reliable results a dynamic measurement system shall: a) for every measurement point, be able to link the position of the photometric head in terms of height, and transverse and longitudinal
38、distances or coordinates to a datum such as the kerb; b) minimize any effects, such as vehicle shadow, light reflection, and electronic noise, the vehicle may have on the detector readings; c) be equipped with photometric heads conforming to the requirements specified in clauses 7 and 8. Measurement
39、s from a moving vehicle should include the information listed in A.11. 5 Non-photometric measurements 5.1 General The selection of non-photometric measurements should be related to the purpose of the measurements. Where measurements are required for comparison with calculated values, detailed non-ph
40、otometric measurements will be required. Where the measurements are required for monitoring the state of an installation then it is possible that less detailed non-photometric measurements will suffice. 5.2 Geometric data On-site measurements should be made of the geometry of the installation. These
41、 should include measurements in plan of the installation, the height of the columns, and the length of the outreach. In addition tilt in application of the luminaires, orientation of the luminaires, and rotation of the luminaires should be measured when possible or when these data may be relevant fo
42、r meeting the objectives of the measurement. EN 13201-4:2003 (E) 6 5.3 Electric tension of supply At the start of a measurement, the electric tension of the supply, at as many lighting columns as is necessary, shall be measured. During the measurement, the electric tension shall be measured continuo
43、usly at a significant point in the electric installation, and observed. A recording voltmeter is preferable for this purpose. 5.4 Temperature The temperature shall be measured at a height of 1,0 m above ground level and recorded at intervals of 30 min. 5.5 Instruments All instruments shall be calibr
44、ated. NOTEThere can be requirements for quality assurance of instruments which may be requested as part of a tender or specification. 6 Location of grid points and observer To assess the agreement between measured and calculated values, the position of the grid points at which measurements are taken
45、 and the position of the observer should agree with those used for the calculation. These latter should be in accordance with one of those given in EN 13201-3. This may involve the taking of a large number of observations, which may be impracticable because of time limitations or other consideration
46、s. In these circumstances, fewer observations may be taken but there will be a loss of accuracy. Maximum and minimum values may be found by searching rather than by recording numerous values over a closely spaced grid. 7 Measurement of illuminance 7.1 General Illuminance shall be measured with an il
47、luminance meter which has a performance suitable for the purpose of the measurements. Where the measurements are required for monitoring purposes, absolute calibration of the illuminance meter is not necessary, but consideration should be given to the long term ageing of the illuminance meter. NOTE
48、1Guidance on the performance of illuminance meters is given in CIE Publication 53:1982 and CIE Publication 69:1987. For the measurement of horizontal and vertical illuminance a photometer head for the measurement of planar illuminance is required. For semicylindrical or hemispherical illuminance a p
49、hotometer head designed for the purpose is required. NOTE 2Hemispherical illuminance at a point can be measured by means of an illuminance meter for measuring planar illuminance by adopting the following procedure. The horizontal illuminance Ehorizontal from all the luminaires is measured at the point. The component E1 is measured from each luminaire in turn by directing the surface of the photometer head so that it receives light at right-angles to its surface from the luminaire being mea
