Communication Concerning the Approval or Extension or Refusal or Withdrawal of
Approval or Production Definitely Discontinued of a Vehicle Type with Regard to the
Speedometer Equipment Including its Installation Pursuant to Regulation No. 39
Annex 2 – Arrangements of Approval Marks
Annex 3 – Test of Speedometer Accuracy for Conformity of Production

2.5. "speedometer" means that part of the speedometer equipment which indicates to the
driver the speed of his vehicle at any given moment;
2.5.1. "tolerances of the speedometers measuring mechanism" shall mean the accuracy of
the speedometer instrument itself, expressed as the upper and the lower speed indication
limits for a range of speed inputs;
2.5.2. "technical constant of the speedometer" shall mean the relationship between the input
revolutions or pulses per minute and a specified displayed speed.
2.6. "odometer" means that part of the odometer equipment which indicates to the driver the
total distance recorded by the vehicle since its entry into service.
2.6.1. "Technical constant of the odometer" means the relationship between the input
revolutions or pulses and the distance travelled by the vehicle.
2.7. "unladen vehicle" means the vehicle in running order, complete with fuel, coolant,
lubricant, tools and a spare wheel (if provided as standard equipment by the vehicle
manufacturer), carrying a driver weighing 75kg, but no driver's mate, optional accessories or

equipment including its installation shall be submitted by the vehicle manufacturer or by his
duly accredited representative.
3.2. It shall be accompanied by the following documents in triplicate and by the following
particulars:
3.2.1. A description of the vehicle type with regard to the items mentioned in Paragraphs 2.2., 2.3.,
2.4., 2.5., and 2.6. above; the vehicle type shall be specified.
3.3. An unladen vehicle representative of the vehicle type to be approved shall be submitted to
the technical service conducting approval tests.
3.4. The competent authority shall verify the existence of satisfactory arrangements for ensuring
effective control of the conformity of production before type-approval is granted.

5. SPECIFICATIONS
5.1. An onboard speedometer and odometer complying with the requirements of this Regulation
shall be fitted to the vehicle to be approved.
5.2. The display of the speedometer must be located within the direct field of view of the driver
and must be clearly legible both day and night. The range of speeds displayed must be
sufficiently wide to include the maximum speed of this type of vehicle as stated by the
manufacturer.
5.2.1. In the case of speedometers intended for vehicles of Categories M, N, and L , L and L , the
graduation shall be 1, 2, 5 or 10km/h. The numerical values of the speed shall be indicated
on the display as follows: when the highest value on the display does not exceed 200km/h,
speed values shall be indicated at intervals not exceeding 20km/h. When the maximum
value on the display exceeds 200km/h, then the speed values shall be indicated at intervals
not exceeding 30km/h. The indicated numerical speed value intervals need not be uniform.
5.2.2. In the case of vehicles of Categories M, N, and L , L and L manufactured for sale in any
country where imperial units are used, the speedometer shall also be marked in mph (miles
per hour); the graduations shall be of 1, 2, 5 or 10mi/h. The numerical values of the speed
shall be indicated on the display at intervals not exceeding 20mi/h and commencing at 10 or
20mi/h. The indicated numerical speed value intervals need not be uniform.
5.2.3. In the case of speedometers intended for vehicles of Categories L (mopeds) and L , the
display readings must not exceed 80km/h. The graduation shall be 1, 2, 5 or 10km/h and the
marked numerical values of the speed indicated shall not exceed 10km/h. The indicated
numerical speed value intervals need not be uniform.
5.3. The accuracy of the speedometer equipment shall be tested in accordance with the
following procedure:
5.3.1. The tyres shall be one of the types normally fitted to the vehicle as defined in Paragraph 2.3.
of this Regulation. A test shall be carried out for each type of speedometer intended to be
fitted by the manufacturer.
5.3.2. The test shall be carried out with the vehicle at its unladen weight. An additional weight can
be carried for purposes of measurement. The weight of the vehicle and its distribution
between the axles shall be indicated in the approval communication (see Annex 1,
Paragraph 6.);
5.3.3. The reference temperature at the speedometer shall be 23 ± 5°C;
5.3.4. During each test the pressure of the tyres shall be the normal running pressure as defined in
Paragraph 2.4.;

7. CONFORMITY OF PRODUCTION
7.1. The conformity of production procedures shall comply with those set out in the Agreement,
Appendix 2 (E/ECE/324-E/ECE/TRANS/505/Rev.2), with the following requirements:
