Different luminous intensities and luminous intensity distributions are recommended for different locations and situations. 6.2 Diameter of signal lights Roundel signal lights for road traffic conditions shall have a nominal diameter of (200 mm or 300 mm) ± 10 %. NOTE As the requirements for visibility depend on the local conditions of road lay-out and infrastructure, on traffic conditions and light conditions, it is not feasible to give strict rules for the situations where either 200 mm or 300 mm roundel signals should be used. 6.3 Luminous intensities of signal lights The performance levels for signal lights, for both 200 mm and 300 mm roundels, shall be as specified in Table 1. NOTE The standard does not give values for reduced output operation.

class 1 Imax
class 2 400 cd 1 100 cd 800 cd 2 000 cd 1 000 cd 2 500 cd
For example the performance level 2/1 is the designation of a signal light with: Imin = 200 cd; Imax = 800 cd. 6.4 Distribution of luminous intensity In Tables 2, 3, 4 and 5 four angular distributions of luminous intensity for signal lights are specified as minimum luminous intensities, expressed as percentage values dependent on the choice of the following categories: A
as a percentage of the measured values on the axis 0° horizontal and 0° vertical (the reference axis); B
as a percentage of the minimum values as defined in Table 1 required on the axis 0° horizontal and 0° vertical (the reference axis). Outside the area described in Tables 2 to 5 (as applicable) the luminous intensities shall not exceed the maximum of the relevant class of performance level. The Tables 2 to 5 contain the minimum luminous intensities in % of the values in their reference axis. Only the listed combinations of classes and performance levels shall be applied. Within the field of measurement, the light pattern shall be substantially uniform, i. e. the light intensity in each direction at each test point shall meet at least the level achieved by the next consecutive measurement.

6.5 Luminance uniformity The luminance uniformity of the roundel as the ratio of the lowest and greatest luminance Lmin : Lmax shall be ≥1 : 10 for types E, W and M and ≥1 : 15 for type N. 6.6 Maximum phantom signal For each signal colour the maximum phantom signal Iph for light incident at an angle of 10° to the reference axis shall comply with of Table 6, where Is is the actual measured luminous intensity I of the signal light: Table 6 — Requirement for the ratio of Is to Iph Signal light function Class 1 Class 2 Class 3 Class 4 Class 5 red, yellow >1 >5 >4 >8 >16 green >1 >5 >8 >16 >16
6.7 Colours of signal lights The colours of signal lights are red, yellow and green and they shall comply with Table 7 when using anti-phantom devices and including combined colours from real signal and all classes of phantom light, except class 1.

6.8 Signal lights with symbols Symbols shall only be placed on roundels of signal lights which demonstrate compliance with 6.3 to 6.7. The optical performance for symbols is derived by using the performance of the full roundel. Class S1: Symbols placed on roundels meeting 100 % of one of the levels set out in Table 1. Class S2: Symbols placed on roundels meeting 50 % of one of the levels set out in Table 1 (only pedestrian traffic). 6.9 Background screen of signal lights Signal lights shall have an opaque background screen or a rim of 25 mm which gives suitable contrast. The background screen may be incorporated in the housing of the signal head or may consist of a detachable screen. The dimensions of the background screen for three-colour-signal heads shall comply with one of the four classes specified in Table 8. The classes are expressed in the overall dimensions (height and width) of the opaque background screen and for 200 mm and 300 mm roundels.

7 Constructional and environmental test methods The test methods for four environmental ranges are detailed in Table 9, Table 10, Table 11 and Table 12. The latter is generally considered an electrical test but in this case ingress of dust and moisture can adversely affect optical performance hence are included in this section.

f4 ≤ 3  Fatigue error f5 ≤ 0,5  Temperature coefficient – α ≤ 0,2 % / K The signal head shall be operated with the manufacturer's equipment. The supplier of the signal head shall specify the operating voltage for the tests. He shall declare the operational tolerances of this value. For all light sources the specification from the manufacturer shall include nominal flux/luminous intensity relative to the specified voltage/wattage and the position of the source in the optical geometry of the signal. The manufacturer shall provide the signal head with light sources and specifications (for the luminous flux or luminous intensity measurements). 8.2 Measurement of luminous intensities The luminous intensity is measured with the optical unit on a goniometer. The angles in Tables 2, 3, 4 and 5 are chosen to correspond with a goniometer, where the horizontal axis is fixed and the vertical axis is moveable in space, see Figure 1 (type 1 CIE
70:1987). For a goniometer with another arrangement the angles have to be recalculated correspondingly (see CIE 54:2001, Annex B). The distance of measurement shall be such that the inverse square distance law is applicable (I = r2E). The measuring equipment shall be such that the angular aperture of the detector viewed from the reference centre of the lamp is ≤10°. The total effect of systematic and random errors in the goniometer shall not exceed:  For measurement of luminous intensity: 5 % of the actual intensity  For measurement of angular direction: beams with half peak side angle: 2° < α
< 4°: 0,1°
4° < α < 8°: 0,2° 8° < α
: 0,4°
Figure 1 — Goniometer for measuring luminous intensities with fixed horizontal axis X 8.3 Measurement of luminance for uniformity tests The measurement of the luminance is performed in the reference axis over the total area of the light emitting surface of the roundel specified by the manufacturer in a diameter of the roundel. The diameter of the circular measuring area shall be 25 mm. The total effect of systematic and random error of luminance measurements shall not exceed 5 %. By scanning with the luminance meter the minimum and maximum luminance shall be detected. 8.4 Measurement of phantom signal For measurements of phantom signal the signal head shall be fitted with its signal light source. The manufac-turer shall specify the light source(s) in accordance with 10.2. The light source generating a phantom signal according to Figure 2 is a projector simulating CIE illuminant A. The light from the projector shall illuminate the light emitting surface of the optical unit with the illuminance E = 40 000 lx and uniformity of 10 %. No hood shall be fitted. The reference axis of the signal head and the axis of the projector shall form an angle of 10°. The maximum permitted angular spread of illuminating directions is limited to 0,5°. The plane formed from both axes shall be the operational vertical plane. The arrangement shall be in a way that the projector radiates the light as if from above the signal head. To avoid also measuring a frontal phantom signal of a convex polished lens it is necessary to cover the image of the projector on the illuminating surface of the optical unit by means of a mask. The diameter of the mask shall be 30 mm (for 200 mm roundels) or 45 mm (for 300 mm roundels). If the illuminance E = 40 000 lx of the roundel cannot be realized the luminous intensity of the phantom light Iph can also be calculated for the lower illuminances El from the corresponding lower luminous intensity Iphl : E IIlphlphlx

(γ
= photometer head aperture, δ
= source aperture) Measurements of phantom signal depend strongly on the geometry of measurement. 10 m distance for measurements is preferred for obtaining comparable results and it should be used to use the following distances and apertures:  photometer head aperture: γ = 10°, corresponding 2,9 cm diameter effective photometer head opening at 10 m distance;  source aperture: δ
= 10°, corresponding 2,9 cm diameter opening of effective light exit at 10 m distance. The photometer shall be placed so that the reference axis of the signal head and the axis of the photometer coincide. With switched on projector the mean luminous intensity Iph in the plane of the illuminating field of the signal head shall to be measured while the signal is switched off. The ratio between the luminous intensity Is of the real signal and the luminous intensity Iph of the phantom signal shall be as given in 6.6 and Table 6. 8.5 Measurement of the colour For the measurement of the colour the arrangement of Figure 2 shall be altered in a way that a colorimeter replaces the photometer. The chromaticity co-ordinates Ps (xs, ys) of the real signal shall be measured with projector switched off. 8.6 Measurement of combined colours The chromaticity coordinates Ps+ph (xs+ph ys+ph) of the mixed light from real signal and phantom signal shall be measured with projector and signal switched on. The illuminance on the illuminating field of the traffic signal shall be E = 40 000 lx. The chromaticity coordinates Ps+ph can also be calculated for the relevant illuminance from the chromaticity coordination Ps (xs, ys) of the pure signal and Pph (xph, yph) of the pure phantom. The chromaticity coordinates Pph (xph, yph) of the pure phantom signal shall to be measured while the projector is switched on and the signal light switched off according to 8.4. The chromaticity co-ordinates are:
