1. SCOPE

This Regulation applies to rear marking plates for vehicles of category M, N, O and T and for mobile machinery, which, by construction, cannot move faster than 40 km/h (1).

2. DEFINITIONS (2)

2.1. For the purpose of these provisions, the following definitions shall apply:

2.1.1. ‘SMV rear marking plate’, a triangular plate with truncated corners with a characteristic pattern faced with retro-reflective and fluorescent material or devices (class 1); or with retro-reflective materials or devices only (class 2).

2.1.2. ‘Sample unit’, a complete, finished SMV plate ready to be mounted on a vehicle and representative of current production.

2.2. Retro-reflection

Reflection in which radiation is returned in directions close to the direction from which it came, this property being maintained even over wide variations of the direction of the incident radiation:

2.2.1. ‘Retro-reflective material’, a surface or device from which, when directionally irradiated, a relatively large portion of the incident radiation is retroreflected.

2.2.2. ‘Retro-reflective device’, an assembly ready for use and comprising one or more retro-reflective optical units.

2.3. Geometric definitions (see Annex 1, figure 1).

2.3.1. ‘Reference centre’, a point on or near a retro-reflective area which is designated to be the centre of the device for the purpose of specifying its performance.

2.3.2. ‘Illumination axis’, a line segment from the reference centre to the light source.

2.3.3. ‘Observation axis’, a line segment from the reference centre to the photometer head.

2.3.4. ‘Observation angle (symbol α)’, the angle between the illumination axis and the observation axis. The observation angle is always positive and, in the case of retro-reflection, is restricted to small angles. Maximum range: 0° ≤ α ≤ 180°.

2.3.5. ‘Observation half-plane’, the half-plane which originates on the illumination axis and which contains the observation axis.

2.3.6. ‘Reference axis’, a designated line segment originating on the reference centre which is used to describe the angular position of the retro-reflective device.

2.3.7. ‘Entrance angle (symbol β)’, the angle from the illumination axis to the reference axis. The entrance angle is usually not larger than 90° but, for completeness, its full range is defined as 0° ≤ β ≤ 180°. In order to specify the orientation in full, this angle is characterised by two components, β1 and β2.

2.3.8. ‘First axis’, an axis through the reference centre and perpendicular to the observation half-plane.

2.3.9. ‘First component of the entrance angle (symbol β1)’, the angle from the illumination axis to the plane containing the reference axis and the first axis. Range: – 180° < β1 ≤ 180°.

2.3.10. ‘Second component of the entrance angle (symbol β2)’, the angle from the plane containing the observation half-plane to the reference axis. Range: – 90° ≤ β2 ≤ 90°.

2.3.11. ‘Second axis’, an axis through the reference centre and perpendicular to both the first axis and the reference axis. The positive direction of the second axis lies in the observation half-plane when – 90° < β1 < 90° as shown in Annex 1, figure 1.

2.3.12. Angle of rotation ε

Angle through which the sample is turned about its vertical axis from any arbitrarily established position counterclockwise (+ ε) or clockwise (– ε) viewed in the direction of illumination. If retro-reflective materials or devices have a marking (e.g. TOP), this marking governs the starting position. The angle of rotation ε lies in the range – 180° < ε ≤ 180°.

2.4. Definition of photometric terms

2.4.1. Coefficient of retro-reflection R’

Coefficient (R’) obtained from the luminous intensity (I) of the retro-reflective area in the direction of observation and the illuminance (E┴) on the retro-reflective plane at right angles to the direction of the incident light and the illuminated plane sample surface A.

The coefficient of retro-reflection R’ is expressed in candela per square metre per lux (cd. m-2. lx-1).

2.4.2. ‘Angular diameter of the retro-reflective sample (symbol η)’, the angle subtended by the greatest dimension of the retro-reflective sample, either at the centre of the source of illumination or at the centre of the receiver.

2.4.3. ‘Luminance factor’, the ratio of the luminance of the body considered to the luminance of a perfect diffuser under identical conditions of illumination and observation.

2.4.4. ‘Colour of the reflected light of the device.’ The definitions of the colour of the reflected light are given in paragraphs 2.30 and 2.31 of Regulation No 48.

2.5. Fluorescence

2.5.1. When certain substances are brought near to a source of ultraviolet or blue radiations, they emit radiations which are nearly always of longer wavelength than those producing the effect. This phenomenon is called fluorescence. By day and in twilight, fluorescent colours are brighter than normal colours because they reflect part of the light falling upon them and in addition they emit light. At night, they are not brighter than ordinary colours

2.5.2. ‘Colour of the fluorescent light of the device.’ The definitions of the colour of the fluorescent light are given in paragraph 2.32 of Regulation No 48.

2.6. Description of goniometer

A goniometer which can be used in making retro-reflection measurements in the CIE geometry is illustrated in Annex 1, figure 2. In this illustration, the photometer head is arbitrarily shown to be vertically above the source. The first axis is shown to be fixed and horizontal and is situated perpendicular to the observation half-plane. Any arrangement of the components which is equivalent to the one shown can be used.

2.7. Definition of ‘type’

SMV rear marking plates of different types means SMV marking plates which differ in such essential respects as:

2.7.1. The trade name or mark.

2.7.2. The characteristics of the retro-reflective material or devices.

The subtended angle at the sample shall not be larger than 80'.

ANNEX 8 RESISTANCE TO EXTERNAL AGENTS 1. RESISTANCE TO WEATHERING 1.1. Procedure — For each test, two specimens of a sample unit (see paragraph 2.1.2 of this Regulation) are taken. One specimen shall be stored in a dark and dry container for subsequent use as ‘reference unexposed specimen’. The second specimen shall be subjected to a source of illumination in accordance with ISO Standard 105-B02-1978, Section 4.3.1; the retro-reflective material shall be exposed until blue standard No 7 has faded to No 4 on the grey scale and the fluorescent material until blue standard No 5 has faded to No 4 on the grey scale. After the test, the specimen shall be washed in a dilute neutral detergent solution, dried and examined for conformity with the requirements specified in paragraphs 1.2 to 1.4. 1.2. Visual appearance — No area of the exposed specimen shall show any evidence of cracking, sealing, pitting, blistering, delamination, distortion, chalking, staining or corrosion. There shall be no shrinkage in excess of 0,5 per cent in any linear direction and no evidence of adhesion failure such as edge lifting from the substrate. 1.3. Colour fastness — The colours of the exposed specimen shall still meet the requirements specified in Annex 6. 1.4. Effect on the coefficient of luminous intensity of the retro-reflective material. 1.4.1. For this check, measurement shall be made only at an observation angle of 20′ and an entrance angle of 5° by the method given in Annex 7. 1.4.2. The coefficient of luminous intensity of the exposed specimen when dry shall be not less than 80 per cent of the value in Annex 7, table 1. 1.4.3. The specimen shall then be subjected to simulated rainfall and its coefficient of luminous intensity under this condition shall be not less than 90 per cent of the value obtained when measured in dry condition, as explained in paragraph 1.4.2 above. 2. RESISTANCE TO CORROSION (ISO Standard 3768) 2.1. A specimen of the sample unit shall be subjected to the action of a saline mist for 48 hours comprising two periods of exposure of 24 hours each, separated by an interval of 2 hours during which the specimen is allowed to dry. The saline mist shall be produced by atomising at a temperature of 35 + 2 °C of a saline solution obtained by dissolving five parts by weight of sodium chloride in 95 parts of distilled water containing not more than 0,02 per cent of impurities. 2.2. Immediately after completion of the test, the sample shall show no sign of corrosion liable to impair the efficiency of the device. 2.2.1. The coefficient of luminous intensity R of the retro-reflective area, when measured after a recovery period of 48 hours as specified in Annex 7, paragraph 1, at an entrance angle of 5° and an observation angle of 20′, shall be not less than the value in Annex 7, table 1. Before measuring, the surface shall be cleaned to remove salt deposits from the saline mist. 3. RESISTANCE TO FUELS A section of a sample unit not less than 300 mm long shall be immersed in a mixture of n-heptane and toluene, 70 per cent and 30 per cent by volume, for one minute. After removal, the surface shall be wiped dry with a soft cloth and shall not show any visible change which would reduce its effective performance. 4. BONDING STRENGTH (in the case of adhesive materials) 4.1. The adhesion of retro-reflective materials shall be determined after 24 hours curing time by utilising a 90-degree peel on a tensile strength testing machine. 4.2. The adhesion of laminated or coated retro-reflective and fluorescent materials shall be determined. 4.3. The coated materials, of whatever kind, shall not be removable without tools or without damaging the material. 4.4. The laminated materials (adhesive films) shall need a force of at least 10 N per 25 mm width at a speed of 300 mm per minute, to be removed from the substrate. 5. RESISTANCE TO WATER A section of a sample unit not less than 300 mm long shall be immersed in distilled water at a temperature of 23 ± 5 °C for a period of 18 hours; it shall then be left to dry for 24 hours under normal laboratory conditions. After completion of the test, the section shall be examined. No part inside 10 mm from the cut edge shall show evidence of deterioration which would reduce the effectiveness of the plate. 6. RESISTANCE TO IMPACT (except for plastics corner-cube reflectors) When a 25 mm diameter solid steel ball is dropped from a height of 2 m on to the retro-reflective and on the fluorescent surfaces of a supported plate, at an ambient temperature of 23 ± 2 °C, the materials shall show no cracking or separation from the substrate at a distance of more than 5 mm from the impacted area. 7. RESISTANCE TO CLEANING 7.1. Manual cleaning 7.1.1. A test sample smeared with a mixture of detergent lubricating oil and graphite shall be easily cleaned without damage to the retro-reflective surface or fluorescent surface when wiped with a mild aliphatic solvent such as n-heptane, followed by washing with a neutral detergent. 7.2. Power washing 7.2.1. When subjected to a continuous spraying action for 60 seconds on the test component in its normal mounting conditions, a test sample shall show no damage to the retro-reflective surface or delamination from the substrate or separation from the sample mounting surface under the following set-up parameters: (a) water/wash solution pressure 8 ± 0,2 MPa; (b) water/wash solution temperature 60 ° – 5 °C; (c) water/wash solution flow rate 7 ± 1 l/min; (d) the tip of the cleaning wand to be positioned at distance of 600 ± 20 mm away from the retro-reflective surface; (e) cleaning wand to be held at no greater angle than 45 degrees from perpendicular to the retro-reflective surface; (f) 40 degree nozzle creating wide fan pattern.

ANNEX 9 RESISTANCE TO HEAT 1. The four samples shall be kept for 48 hours in a dry atmosphere at a temperature of 65 ± 2 °C, after which the samples shall be allowed to cool for 1 hour at 23 ± 2 °C. They shall then be kept for 12 hours at a temperature of – 20 ± 2 °C. 1.1. The sample shall be examined after a recovery time of 4 hours under normal laboratory conditions. 2. After this test, no cracking or appreciable distortion of the surfaces, particularly of the optical units, shall be evident.

ANNEX 10 RIGIDITY OF THE PLATES The triangular plate shall be strongly held on one of its long sides, with the clamps of the holding device not encroaching over more than 20 mm. A force of 10 N perpendicular to the plane shall be applied to the opposite apex. The apex shall then not move in the direction of the force by more than 40 mm. After removal of the force, the plate shall visibly return to its initial position. The residual deflection shall not be more than 5 mm.

ANNEX 11 Stability in time of the optical properties (1) of rear marking plates 1. The authority which granted approval shall have the right to check the stability in time of the optical properties of a type of rear marking plate in service. 2. The Competent Authorities of countries other than the country in which approval was granted may carry out similar checks in their territory. If a type of rear marking plate in use exhibits a systematic defect, the said authorities shall transmit to the authority which granted approval, with a request for its opinion, any components removed for examination. 3. In the absence of other criteria, the concept of ‘systematic defect’ of a type of rear marking plate in use shall be interpreted in conformity with the intention of paragraph 6.1 of this Regulation. (1) Despite the importance of tests to check the stability in time of the optical properties of rear marking plates, it is in the present state of the art not yet possible to assess this stability by laboratory tests of limited duration.

ANNEX 13 Minimum requirements for conformity of production control procedures 1. GENERAL 1.1. The conformity requirements shall be considered satisfied from a mechanical and geometric standpoint, if the differences do not exceed inevitable manufacturing deviations within the requirements of this Regulation. 1.2. With respect to photometric performances, the conformity of mass-produced rear marking plates shall not be contested if, when testing photometric performances of any rear marking plate chosen at random, no measured value deviates unfavourably by more than 20 per cent from the values prescribed in this Regulation. 1.3. The chromaticity coordinates shall be complied with. 2. MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE MANUFACTURER For each type of rear marking plate the holder of the approval mark shall carry out at least the following tests, at appropriate intervals. The tests shall be carried out in accordance with the provisions of this Regulation. If any sampling shows non-conformity with regard to the type of test concerned, further samples shall be taken and tested. The manufacturer shall take steps to ensure the conformity of the production concerned. 2.1. Nature of tests Tests of conformity in this Regulation shall cover the photometric and colorimetric characteristics and the test of weather resistance of these characteristics. 2.2. Methods used in tests 2.2.1. Tests shall generally be carried out in accordance with the methods set out in this Regulation. 2.2.2. In any test of conformity carried out by the manufacturer, equivalent methods may be used with the consent of the competent authority responsible for approval tests. The manufacturer is responsible for proving that the applied methods are equivalent to those laid down in this Regulation. 2.2.3. The application of paragraphs 2.2.1 and 2.2.2 requires regular calibration of test apparatus and its correlation with measurements made by a competent authority. 2.2.4. In all cases the reference methods shall be those of this Regulation, particularly for the purpose of administrative verification and sampling. 2.3. Nature of sampling Samples of rear marking plates shall be selected at random from the production of a uniform batch. A uniform batch means a set of rear marking plates of the same type, defined according to the production methods of the manufacturer. The assessment shall in general cover series production from individual factories. However, a manufacturer may group together records concerning the same type from several factories, provided these operate under the same quality system and quality management. 2.4. Measured and recorded photometric characteristics The sampled rear marking plate shall be subjected to photometric measurements for minimum values at the points and chromaticity coordinates provided for in the Regulation. 2.5. Criteria governing acceptability The manufacturer is responsible for carrying out a statistical study of the test results and for defining, in agreement with the Competent Authority, criteria governing the acceptability of his products in order to meet the specifications laid down for verification of conformity of products in paragraph 9.1 of this Regulation. The criteria governing the acceptability shall be such that, with a confidence level of 95 per cent, the minimum probability of passing a spot check in accordance with Annex 14 (first sampling) would be 0,95.
