PROPOSAL FOR DRAFT AMENDMENTS TO REGULATION No. 39

(Speedometer equipment)

Transmitted by the Expert from Sweden

Note: The text reproduced below was prepared by the expert from Sweden in order to harmonize the speedometer requirements with those of the European Directives and to adapt it to technical progress. It is based on document TRANS/WP.29/GRSG/1999/14 and the proposed European Community Directive for speedometers for two- or three-wheel motor vehicles. It supersedes document TRANS/WP.29/GRSG/1999/14.

" ...... a maximum design speed exceeding 25 km/h."

Paragraphs 2.2. to 2.2.3., amend to read:

"2.2.	"type of vehicle in respect of its speedometer" means vehicles which do not among themselves display any essential differences, where those differences can apply, in particular, to the following:"

2.2.1.	the size designation of the tyres chosen from the range of tyres normally fitted;

2.2.2.	the overall transmission ratio, including any reduction drives, to the speedometer;

2.2.3.	the type of speedometer as characterised by:

2.2.3.1.	the tolerances of the speedometer's measuring mechanism;

2.2.3.3.	the range of speeds displayed."

Insert new paragraphs 2.5.1. and 2.5.2., to read:

200 km/h, speed values shall be indicated at intervals not exceeding 20 km/h. When the maximum value on the dial exceeds

200 km/h, then the speed values shall be indicated at intervals not exceeding 30 km/h. The indicated numerical speed value intervals need not be uniform."

5.1.3.1.	In addition, the dial must show the speed of 45 km/h clearly and

25 km/h where the speedometer is intended for fitting to a vehicle of category L1 having a maximum design speed not exceeding 25 km/h."

Paragraph 5.1.2. (former), renumber as paragraph 5.1.4. and amend to read:

"5.1.4.	In the case of vehicles of categories M, N, and L2, L3, L4 and L5 manufactured for sale in any country where imperial units are used, the speedometer shall also be marked in mph (miles per hour); the graduation shall be of 1, 2, 5 or 10 mph. The numerical values of the speed shall be indicated on the dial at intervals not exceeding 20 mph and commencing at 10 or 20 mph. The indicated numerical speed value intervals need not be uniform."

Insert new paragraphs 5.1.5 and 5.1.5.1., to read:

"5.1.5.	In the case of vehicles of categories L1 (mopeds) manufactured for sale in any country where imperial units are used, the speedometer shall also be marked in mph (miles per hour); the graduation shall be of 1, 2, 5 or 10 mph. The highest value indicated on the dial shall not exceed 50 mph. The numerical values of the speed shall be indicated on the dial at intervals not exceeding 10 mph. The indicated numerical speed value intervals need not be uniform.

5.1.5.1.	In addition, the dial must show the speed of [30] mph clearly and 15 mph where the speedometer is intended for fitting to a vehicle of category L1 having a maximum design speed not exceeding 15 mph."

Paragraph 5.2.1., amend to read:

"5.2.1.	The tyres will be one of the types normally fitted to the vehicle as defined in paragraph 2.3. of this Regulation. A test will have to be carried out for each type of speedometer intended to be fitted by the manufacturer."

Paragraph 5.2.5., amend to read:

"5.2.5.	The vehicle is tested at the following speeds:

Maximum design speed (Vmax) of the vehicle specified by the vehicle manufacturer
