EN 12368:2015 (E) 6 Introduction Signal heads are mainly used to transfer safety messages to the road user to achieve specific reactions. Signal heads in road traffic transfer this information optically by signal lights which have a specific meaning and which differ in their colour of light and in the design of their illuminating surface. The visibility of a signal light depends on the colour, luminous intensity, luminous intensity distribution, luminance and luminance uniformity, the surrounding luminance (background luminance), the size of the illuminating area of the signal light, the phantom light and the distance and angle between observer and signal head. Four angular distributions of luminous intensities for signal lights are specified. The user can choose between an extra wide, wide, medium and narrow beam signal to obtain a good recognition of the signal for short distances in urban areas, for long distances in rural areas. To achieve a good performance the standard provides a number of different performance levels and two different diameters for the roundels. This European Standard does not require limits for the recognition of red or green signals with reduced luminous intensities operating in a failure mode. These limits depend on the surrounding lights (on or off) and on the situation. However, for a simple rule a red signal is considered as failed if the luminous intensity in the reference axes is I ≤ 10 cd, and a green signal is considered as being in operation if the luminous intensity is I ≥ 0,05 cd. The working environment for signal heads is relatively harsh and equipment that is deemed "fit for purpose" is expected to last in this exposed, corrosive environment for a minimum of 10 years. It is essential that all materials and manufacturing processes take this into account. The supplier should detail all steps taken to comply with this clause. The optical performance of signal heads in use is a function of lens soiling, mirror soiling and a decrease of luminous flux from the lamp. To maintain the performance of the signal heads during service, it is important to ensure that after lamp replacement and cleaning of lens and mirror the light output is restored to as near 100 % as possible and never lower than 80 % of the declared specified performance(s). For devices randomly selected from series production it is important that the product characteristic as to minimum luminous intensity of the light emitted, are in each relevant direction, of the minimum values prescribed.

EN 12368:2015 (E) 7 1 Scope This European Standard applies to signal heads with one or more signal lights of the colours red, yellow and/or green signal lights for road traffic with 200 mm and 300 mm roundels and to optical units to be integrated in signal heads to produce the individual signal lights. It defines the product characteristics for the visual, structural, environmental performances and testing of signal heads and optical units for pedestrian and road traffic use. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

Any component requiring replacement shall be designed such that this is easily accommodated and does not affect the optical performance of the signal head. The construction and choice of materials shall be such that they will provide declared performance for a reasonable economic lifetime of the product as verified by the relevant tests given in this European Standard. The complete signal head shall pass the tests specified in Clause 7 for impact resistance, constructional integrity, ingress and tolerance to temperature, damp heat and solar radiation. SIST EN 12368:2015



EN 12368:2015 (E) 9 The manufacturer shall detail in his documentation what maintenance shall be carried out, including cleaning methods and materials, to ensure that the optical performance shall be maintained to at least 80 % of the minimum values set out in the appropriate parts of 6.3 and 6.4. During the declared lifetime of the optical unit the colours shall remain within the colour boxes of Table 7. 4.2 Signal head There are 5 classes for the Ingress Protection, IP, rating in accordance with EN 60529 of a signal head: Class I: IP34 Class II: IP44 Class III: IP54 Class IV: IP55 Class V: IP65 Where separate protection of the optical units is required they shall be protected to IP55 or IP65. NOTE A level of sealing in accordance with IP65 may result in a risk of water collection within the optic housing due to condensation. The signal head, including its optical components, shall be so designed that after installation, during its lifetime as defined by the supplier, including any replacement of components, the optical and mechanical product characteristics are guaranteed. 4.3 Performance under impact product characteristic There are 3 classes of performance under impact, IR1, IR2 and IR3. When required by the regulatory authority this characteristic shall be determined in accordance with Clause 7 Constructional and environmental test methods Table 8 — Impact resistance. 4.4 Constructional integrity product characteristic The product is expected to survive levels of vibration that may be expected in normal operation.

EN 12368:2015 (E) 10 5.2 Electrical safety and EMC characteristics The signal heads shall comply with the requirements of EN 50293. Whilst this specification is for a traffic signal product, it is clear that this product is connected to a “Traffic system” and as such the connections/wiring etc that is required between it and any controller shall meet the requirements of EN 50556 for electrical safety and in particular attention is drawn to 5.1 Electric safety. 6 Optical Product Characteristics 6.1 General The optical units of a signal head should normally be of the same classes regarding luminous intensity, dimming, distribution of luminous intensity and phantom light, but it is permissible in special cases that the classes are different. EXAMPLE In signal head with red, yellow and green signals it may be requested that the red be brighter than the yellow and green on high speed roads. 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 %. 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. Table 1 — Luminous intensities (I) for red, yellow and green signal lights in the reference axis Performance level 1 2 3 Imin 100 cd 200 cd 400 cd Imax class 0 Imax class 1 Imax class 2 200 cd 400 cd 1 100 cd 400 cd 800 cd 2 000 cd 600 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. Dimmed operation is an operating mode of the road traffic signal system in which the luminous intensity of the signal heads is reduced. These classes of dimmed operation are available: Class D0 Dimmed operation is not required. Class D1 As declared by the manufacturer. For Class D1, the manufacturer shall declare the performance of their signal in dimmed operation against the optical product characteristics of this specification and operational voltage ranges. NOTE Refer to CLC/TS 50509 Annex B regarding dimmed operation in the Netherlands and Annex C regarding dimmed operation in Spain. SIST EN 12368:2015



EN 12368:2015 (E) 11 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. e.g. if at 0,0 the measurement is 100 and at +5 the measurement is 85 then in between the two a measurement shoul
