REGULATION NO. 70-01
UNIFORM PROVISIONS CONCERNING THE APPROVAL OF REAR
MARKING PLATES FOR HEAVY AND LONG VEHICLES
1. SCOPE
This Regulation applies to rear marking plates for the following vehicles :
1.1. Articulated vehicles of Category M, Classes II and III;
1.2. Vehicles of Category N , with a maximum mass exceeding 7.5 t and N , except tractors for
semi-trailers;
1.3. Vehicles of Category O , O and O exceeding 8.0m in length;
1.4. Vehicles of Category O .
2. DEFINITIONS
2.1. For the purpose of these provisions, the following definitions shall apply:
2.1.1. "Rear marking plate" a plate faced with retro-reflective and fluorescent material or devices
intended to increase the visibility and permit easy identification of heavy and long vehicles;
2.1.2. "Sample unit" a complete, finished marking plate ready to be mounted on a vehicle and
representative of current production;
2.1.3. Class(es) of Rear Marking Plates
Class 1:
Class 2:
Class 3:
Class 4:
Class 5:
Rear marking plates for heavy motor vehicles (trucks and tractors) with red
fluorescent and yellow retro-reflective alternative stripes.
Rear marking plates for long vehicles (trailers and semi-trailers) with red
fluorescent border and yellow retro-reflective centre.
Rear marking plates for heavy motor vehicles (trucks and tractors) with red
retro-reflective and yellow retro-reflective alternative stripes.
Rear marking plates for long vehicles (trailers and semi-trailers) with red
retro-reflective border and yellow retro-reflective centre.
Rear marking plates for motor vehicles or trailers with red and white
retro-reflective alternative stripes.

2.3.12 "Angle of rotation ε" angle through which the sample is turned about its mean vertical 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')" the quotient of the coefficient of luminous intensity R
of a plane retro-reflecting surface by its area A. The symbol is R'

⎜R
' =
⎝ E
Ι
⊥ ⋅


A ⎠
The coefficient (R') is expressed in candelas per lux per m (cd.lx .m );
2.4.2. "Angular diameter of the retro-reflector 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 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 wave-length 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 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.

5. APPROVAL
5.1. If the marking plates submitted for approval in accordance with Paragraph 4 above meet the
requirements of this Regulation, approval for this type of marking plate shall be granted.
5.2. An approval number shall be assigned to each type-approved. Its first two digits (at present
01) shall indicate the series of amendments incorporating the most recent major technical
amendments made to the Regulation at the time of issue of the approval. The symbol above
the circle indicates the classes of rear marking plate, "RF" in the case of Classes 1 and 2
(retro-reflective and fluorescent materials) and "RR" in the case of Classes 3 and 4 (retroreflective
only materials). The same Contracting Party may not assign the same number to
another type of rear marking plate.
5.3. Notice of approval or refusal or extension of approval of a type of rear marking plate under
this Regulation shall be communicated to the Parties to the Agreement which apply this
Regulation by means of a form conforming to the model in Annex 2 to this Regulation and of
a drawing annexed thereto supplied by the applicant for approval, in a format not exceeding
A4 (210 × 297mm ) or folded to that format and if possible on a scale of 1 : 1.
5.4. Every marking plate conforming to a type-approved under this Regulation shall bear, in
addition to the marking 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.

methods applied in each production facility. The normal frequency of these verifications
shall be once every two years.
10. PENALTIES FOR NON-CONFORMITY OF PRODUCTION
10.1. The approval granted in respect of a type of marking plate pursuant to this Regulation may
be withdrawn if the requirements set forth above are not met or if a marking plate bearing
the approval mark does not conform to the type-approved.
10.2. If a Party to the Agreement applying this Regulation withdraws an approval it has previously
granted, it shall forthwith so notify the other Contracting Parties applying this Regulation by
means of a communication form conforming to the model in Annex 2 to this Regulation.
