REGULATION NO. 69-01
UNIFORM PROVISIONS CONCERNING THE APPROVAL OF REAR MARKING PLATES FOR SLOW
MOVING VEHICLES (BY CONSTRUCTION) AND THEIR TRAILERS
1. SCOPE
This Regulation applies to rear marking plates for vehicles of Categories M, N, O and T and
for mobile machinery, which, by construction, cannot move faster than 40km/h .
2. DEFINITIONS
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 retro reflected.
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°.

2.4.4. "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.
2.7.3. The Characteristics of the Fluorescent Material.
2.7.4. The Parts Affecting the Properties of the Retro-reflective Material or Devices.
3. APPLICATION FOR APPROVAL
3.1. The application for approval of a type of SMV rear marking plate shall be submitted by the
holder of the trade name or mark, or if necessary by his duly accredited representative and
shall be accompanied by:
3.1.1. Drawings, in triplicate, sufficiently detailed to permit identification of the type. The drawings
shall show geometrically the position in which the SMV rear marking plate is to be fitted to
the rear end of the vehicles. They shall also show the position intended for the approval
number and the identification symbol in relation to the circle of the approval mark.
3.1.2. A brief description giving the technical specifications of the materials of which the
retro-reflective areas are made.

5.4. Every SMV rear marking plate conforming to a type-approved under this Regulation shall
bear, in addition to the markings prescribed in Paragraph 4.1.
5.4.1. An international approval mark consisting of:
5.4.1.1. A circle surrounding the Letter "E" followed by the distinguishing number of the country
which has granted approval.
5.4.1.2. An approval number.
5.5. The approval mark shall be clearly legible and shall be indelible.
5.6. Annex 3 to this Regulation gives an example of the arrangement of the approval mark.
6. GENERAL SPECIFICATIONS
6.1. SMV rear marking plates shall be so constructed that they function satisfactorily and will
continue to do so in normal use. In addition, they shall not have any defect in design or
manufacture that is detrimental to their efficient operation or to their maintenance in good
condition.
6.2. The components of retro-reflective/fluorescent SMV rear marking plates (Class 1) or
retro-reflective only SMV rear marking plates (Class 2) shall not be capable of being easily
dismantled.
6.3. The means of attachment of the SMV rear marking plate shall be such that they allow a
stable and durable connection between the plate and the rear end of vehicles, for instance
by screws or rivets.
6.4. The outer surface of the retro-reflective/fluorescent SMV rear marking plate (Class 1) or
retro-reflective only SMV rear marking plate (Class 2) shall be easy to clean. The surface
shall therefore not be rough and any protuberances it may exhibit shall not prevent easy
cleaning.
7. SPECIAL SPECIFICATION (TESTS)
7.1. SMV rear marking plates shall also satisfy the conditions as to dimensions, shape, pattern
and the colorimetric, photometric, physical and mechanical requirements set forth in
Annexes 5 to 12 of this Regulation.

11. PRODUCTION DEFINITELY DISCONTINUED
If the holder of the approval completely ceases the manufacture of an SMV rear marking
plate approved in accordance with this Regulation, he shall so inform the authority which
granted the approval. Upon receiving the relevant communication, that authority shall inform
thereof the other Parties to the Agreement applying this Regulation by means of a
communication form conforming to the model in Annex 2 to this Regulation.
