2.3. "Retro-reflecting optical unit" means a combination of optical components producing retroreflection.
2.4. "Retro-reflecting device" / means an assembly ready for use and comprising one or more retro-reflecting optical units.
2.5. "Angle of divergence" means the angle between the straight lines connecting the centre of reference to the centre of the receiver and to the centre of the source of illumination.
2.6. "Illumination angle" means the angle between the axis of reference and the straight line connecting the centre of reference to the centre of the source of illumination.
2.7. "Angle of rotation" means the angle through which the retro-reflecting device is rotated about its axis of reference starting from one given position.
2.8. "Angular diameter of the retro-reflecting device" means the angle subtended by the greatest dimension of the visible area of the illuminating surface, either at the centre of the source of illumination or at the centre of the receiver.
2.9. "Illumination of the retro-reflecting device" is the abbreviated expression used conventionally to designate the illumination measured in a plane perpendicular to the incident rays and passing through the centre of reference.
2.10. "Coefficient of luminous intensity (CIL)" means the quotient of the luminous intensity reflected in the direction considered, divided by the illumination of the retro-reflecting device for given angles of illumination, divergence and rotation.
2.11. The symbols and units used in this Regulation are given in annex 1 to this Regulation.
2.12. A type of "retro-reflecting device" is defined by the models and descriptive literature submitted with the application for approval. Retro-reflecting devices can be considered as belonging to the same type if they have one or more "retro-reflecting optical units" which are identical with those of the standard model, or if not identical are symmetrical and suitable for mounting one on the left and one on the right side of the vehicle, and if their other parts differ from those of the standard model only in ways not affecting the properties to which this Regulation applies.
2.13. Retro-reflecting devices are divided into three classes according to their photometric characteristics: Class IA or IB, Class IIIA and Class IVA.
2.15. Retro-reflecting devices are divided into three classes according to their photometric characteristics: Class IA or IB, Class IIIA and Class IVA.
2.16. Retro-reflecting devices of Class IB are devices combined with other signal lamps which are not watertight according to annex 8, paragraph 1.1., and which are integrated into the body of a vehicle.

Annex 4
TEST PROCEDURE - CLASS I A AND CLASS III A
The applicant shall submit for approval ten samples which shall be tested in the chronological order indicated in annex 12.
After verification of the general specifications (paragraph 6 of the Regulation) and the specifications of shape and dimensions (annex 5), the ten samples shall be subjected to the heat resistance test described in annex 10 to this Regulation and at least one hour after this test examined as to their colorimetric characteristics (annex 6) and CIL (annex 7) for an angle of divergence of 20' and an illumination angle V = H = 0 degrees or if necessary, in the position defined in annex 7, paragraphs 4 and 4.1. The two retro- reflecting devices giving the minimum and maximum values shall then be fully tested as shown in annex 7. These two samples shall be kept by the laboratories for any further checks which may be found necessary. The other eight samples shall be divided into four groups of two:
First Group:
The two samples shall be subjected successively to the water penetration test (Annex 8, paragraph 1.1.) and then, if this test is satisfactory, to the tests for resistance to fuels and lubricants (Annex 8, paragraphs 3 and 4).
Second Group:
The two samples shall, if necessary, be subjected to the corrosion test (annex 8, paragraph 2), and then to the abrasive-strength test of the rear face of the retro-reflecting device (annex 8, paragraph 5).
Third Group:
The two samples shall be subjected to the test for stability in time of the optical properties of retro-reflecting device (annex 9).
Fourth Group:
The two samples shall be subjected to the colour-fastness test (annex 11).
After undergoing the tests referred to in the above paragraph, the retro-reflecting devices in each group must have:
3.1. a colour which satisfies the conditions laid down in annex 6. This shall be verified by a qualitative method and, in case of doubt, confirmed by a quantitative method.
3.2. a CIL which satisfies the conditions laid down in annex 7. The verification shall be performed only for an angle of divergence of 20 and an illumination angle of V = H = 0 degrees or, if necessary, in the position specified in annex 7, paragraphs 4 and 4.1.
Annex 5
SPECIFICATIONS OF SHAPE AND DIMENSIONS
SHAPE AND DIMENSIONS OF RETRO-REFLECTING DEVICES IN CLASS IA OR IB
1.1. The shape of the illuminating surfaces must be simple, and not easily confused at normal observation distances, with a letter, a digit or a triangle.
1.2. The preceding paragraph notwithstanding, a shape resembling the letters or digits of simple form O, I, U or 8 is permissible.
SHAPE AND DIMENSIONS OF RETRO-REFLECTING DEVISES IN CLASS III A
(See appendix to this annex)
2.1. The illuminating surfaces of retro-reflecting devices in Class III A must have the shape of an equilateral triangle. If the word "TOP" is inscribed in one corner, the apex of that corner must be directed upwards.
2.2. The illuminating surface may or may not have at its centre a triangular, non-retro- reflecting area, with sides parallel to those of the outer triangle.
2.3. The illuminating surface may or may not be continuous. In any case, the shortest distance between two adjacent retro-reflecting optical units must not exceed 15mm.
2.4. The illuminating surface of a retro-reflecting device shall be considered to be continuous if the edges of the illuminating surfaces of adjacent separate optical units are parallel and if the said optical units are evenly distributed over the whole solid surface of the triangle.
2.5. If the illuminated surface is not continuous, the number of separate retro-reflecting optical units including the corner units shall not be less than four on each side of the triangle.
2.5.1. The separate retro-reflecting optical units shall not be replaceable unless they consist of approved retro-reflecting devices in Class I A.
2.6. The outside edges of the illuminating surfaces of triangular retro-reflecting devices in Class III A shall be between 150 and 200mm long. In the case of devices of hollow- triangle type, the width of the sides, measured at right angles to the latter, shall be equal to at least 20% of the effective length between the extremities of the illuminating surface.
SHAPE AND DIMENSIONS OF RETRO-REFLECTING DEVICES IN CLASS IV A
3.1. The shape of the light emitting surfaces must be simple and not easily confused at normal observation distances with a letter, a digit or a triangle. However, a shape resembling the letters and digits of simple form, O, I, U and 8 is permissible.
3.2. The light emitting surface of the retro-reflecting device must be at least 25cm2.
COMPLIANCE WITH THE ABOVE SPECIFICATIONS SHALL BE VERIFIED BY VERIFIED BY VISUAL INSPECTION.

Note: These sketches are for illustration purposes only.
Annex 6
COLORIMETRIC SPECIFICATIONS
These specifications shall apply only to clear, red or amber retro-reflecting devices.
1.1. Retro-reflecting devices may consist of a combined retro-reflecting optical unit and filter, which must be so designed that they cannot be separated under normal conditions of use.
1.2. The colouring of retro-reflecting optical units and filters by means of paint or varnish is not permitted.
When the retro-reflecting device is illuminated by ICI standard illuminant A, with an angle of divergence of 1/3 degrees and an illumination angle V=H= 0 degrees, or, if this produces a colourless surface reflection, an angle V= +/- 5 degrees, H = 0 degrees, the trichromatic coordinates of the reflected luminous flux must be within the following limits:
RED: Limit towards yellow: y < 0.335
Limit toward purple: z < 0.008
AMBER: Limit towards yellow y < 0.429
Limit towards red: y < 0.398
Limit towards white: z > 0.007
2.1. In the case of red and amber, compliance with the colorimetric specifications shall be verified by a visual comparison test.
2.2. If any doubt remains after this test, compliance with the colorimetric specifications shall be verified by determining the trichromatic co-ordinates of the most doubtful sample.
Clear retro-reflecting devices must not produce a selective reflection, that is to say, the trichromatic co-ordinates "x" and "y" of the standard illuminant "A" used to illuminate the retro-reflecting device must not undergo a change of more than 0.01 after reflection by the retro-reflecting device.
3.1. This shall be verified by the visual comparison test indicated above, the control field being illuminated by a light source of which the trichromatic coordinates differ by 0.01 from that of standard illuminant A.
3.2. In case of doubt, the trichromatic coordinates for the most selective sample shall be determined.
Annex 7
PHOTOMETRIC SPECIFICATIONS
When applying for approval, the applicant shall specify the axis of reference. This corresponds to the illumination angle V = H = 0 degrees in the table of coefficients of luminous intensity (CIL).
For photometric measurements only the illuminating surface contained within a circle of 200mm diameter for Class IA or IB shall be considered, and the illuminating surface itself shall be limited to 100cm2 though the surfaces of the retro-reflecting optical units need not necessarily attain this area. The manufacturer shall specify the perimeter of the area to be used. In the case of Class III A and IV A the whole of the illuminating surfaces shall be considered without limitation as to size.
CIL values
3.1. Class IA, Class IB and Class IIIA
3.1.1. The CIL values for red retro-reflecting devices must be at least equal to those in the table below, expressed in millicandelas per lux, for the angles of divergence and illumination shown.
CIL values lower than those shown in the last two columns of the above table are not permissible within the solid angle having the reference centre as its apex and bounded by the planes intersecting along the following lines:
(V = +/- 10 degrees, H = 0 degrees)
(V = +/- 5 degrees, H = +/- 20 degrees).
3.1.2. CIL values for amber retro-reflecting devices in class IA or IB must be at least equal to those in the table of paragraph 3.1.1. above multiplied by the coefficient 2.5;
3.1.3. CIL values for colourless retro-reflecting devices in class IA or IB must be at least equal to those in the table of paragraph 3.1.1. above multiplied by the coefficient 4.

After verification of the specifications in paragraphs 6.1. to 6.5. and the specifications of shape and dimensions (annex 5), the ten samples shall be subjected to the heat resistance test (annex 10) and one hour minimum after this test examined as to their colorimetric characteristics (annex 6) and CIL (annex 7) for an angle of divergence of 20' and an illumination angle V = H = 0 degrees or, if necessary, in the positions defined in annex 7. The two retro-reflecting devices giving the minimum and maximum values shall then be fully tested as shown in annex 7. These two samples shall be kept by the laboratories for any further checks which may be found necessary.
Four samples out of the remaining eight samples shall be selected at random and divided into two groups of two in each group.
First group:
The two samples shall be subjected successively to the water-penetration resistance test (annex 8, paragraph 1) and then, if this test is satisfactory, to the tests for resistance to fuels and lubricating oils (annex 8, paragraphs 3 and 4).
Second group:
The two samples shall, if relevant, be subjected to the corrosion test (annex 8, paragraph 2), and then to the abrasive-strength test of the rear face of the retro-reflecting device (annex 8, paragraph 5). These two samples shall also be subjected to the impact test (annex 13).
After undergoing the tests referred to in the above paragraph, the retro-reflecting devices in each group must have:
4.1. A colour which satisfies the conditions laid down in annex 6. This shall be verified by a qualitative method and, in case of doubt, confirmed by a quantitative method;
4.2. A CIL which satisfies the conditions laid down in annex 7. Verification shall be performed only for an angle of divergence of 20' and an illumination angle of V = H = 0 degrees or, if necessary, in the positions specified in annex 7.
The four remaining samples can be utilized, if necessary, for any other purpose.
Retro-reflecting devices of Class IB shall be tested according to the test procedures specified in Annex 4, following the chronological order of tests given in annex 12, with the exception of the test according to annex 8, paragraph 1, which for Class IB devices may be replaced by the test specified in annex 8, paragraph 1.2.
