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. e.g. if at 0,0 the measurement is 100 and at +5 the measurement is 85 then in between the two a measurement should be at least 85. If doubt arises during the testing of luminance (test 8.2), then test 8.2 can be stopped and Uniformity test 8.3 can be completed. It should be noted that the maximum luminous intensity is defined by the classes selected by the regulatory authority from Table 1 — Luminous intensities (I) for red, yellow and green signal lights in the reference axis SIST EN 12368:2015

Phantom light may cause ambiguity as to which signal lights are on or off unless it is weak in comparison to the signal itself. Phantom light can be reduced by particular designs of the optics, black interiors, anti-phantom devices or hoods etc. Care shall be taken to ensure that the phantom light is weak in all relevant situations. NOTE Traditional signal lights with incandescent lamps and roundels with the inherent colour of the signal lights, either red, yellow or green. This points to a lower value of Iph for green than for red or yellow during measurement, because the illumination is by reddish light (CIE illuminant A, refer to 8.4). However, illumination by the sun – even in a low position – is not as reddish and does not point to quite as low a value for green. This is the reason that some of the classes (classes 3 and 4) have higher requirements to the ratio of Is to Iph for green than for red and yellow - higher ratios can be reached during the measurement of traditional signal lights and are needed as a safeguard in practical conditions. This explanation does not apply for signal lights with non-coloured optics, but it may still be a concern in some cases to ensure that the phantom signal of green signal lights is particularly weak. 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.

Operational test means to look for correct operation of the light source. 8 Optical test methods 8.1 General The described test methods are for indoor (laboratory) measurements in an environment of draft-free air and a temperature of (25 ± 2) °C. The photometer or spectrophotometer used for the measurement of luminous intensity and luminance shall be stable, not subject to fatigue and have a linear response in the relevant range. In addition, the spectral sensitivity shall closely follow the CIE spectral luminous efficiency curve V() in order to ensure a maximum error of 3 % even for light sources with emission in narrow bands of wavelengths such as red, yellow and green LED’s. NOTE The photometer or spectrophotometer may be subjected to the following requirements according to CIE 69: — V f1 ≤ 3 % — Linearity error f3 ≤ 1 % — Display unit error
f4 ≤ 3 % — Fatigue error
f5 ≤ M,5 % — Temperature coefficient
. ≤ M,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 ≤ 1M’ (minutes of arc). The total effect of systematic and random errors in the goniometer shall not exceed: a) For measurement of luminous intensity: 5 % of the actual intensity SIST EN 12368:2015

: 0,4 Light sources shall be suitably aged so that their electrical and optical characteristics are stable. Prior to measurement, the optical unit shall have been in operation in order to stabilize. Red and green optical units are stabilized for at least 30 min with constant light after which measurements can be performed at leisure. Yellow optical units are stabilized for 15 min in a flashing mode with (60 ± 1) flashes per minute (1 Hz) and a light dark ratio of 1:1 after which measurements can be performed with constant light within at most 2 min. NOTE The light output from some yellow optical units based on yellow LED’s is particularly sensitive to temperature rise from self-generated heating during operation. However, yellow optical units are not operated continuously during long intervals and, therefore, it is not necessary to require the same stabilization procedure for yellow as for red and green optical units.
Figure 1 — Goniometer for measuring luminous intensities with fixed horizontal axis X 8.3 Measurement of luminance for uniformity tests The light emitting surface of an optical unit shall appear as essentially circular, not hexagonal, elliptical or any other characteristic shape deviating from circular. Local luminance values of the light emitting surface shall be measured on the reference axis with a circular measuring field of a diameter of 25 mm. This field is moved by translation in both directions, or rotation about the optical axis in successive steps of a maximum pitch of 25 mm (in any direction) so as to have covered the entire light emitting surface. For those cases, where the measuring field is fully within a central circular area of the light emitting surface of a diameter of 180 mm for 200 mm roundels and 270 mm for 300 mm roundels, the smallest and the greatest luminance values are selected and the luminance ratio is calculated as the ratio of the two.
