Informal Group on the Installation of Agricultural Vehicle Lighting | Session 3 | 2-3 Dec 2013
Bonn
Agenda Item 4.
Discussion of amendments to UN R86

4. The comments received on AVLI-01-03/Rev.1 (AVLI-02-03/Rev.1) were discussed.

5. Detailed information on the decisions taken can be found in document AVLI-02-03/Rev.2. In the meeting all comments received on the proposal have been discussed finally. For nearly all comments, there could be found a consensus in the AVLI group.

6. However, there are three items where the final decision will be taken by GRE during its 71th session on 31 March to 4 April 2014. It concerns:
- reversing lamp
- rear fog lamp
- daytime running lamp.

There was no consensus whether the installation of these lamps should be optional or mandatory. Therefore the term “optional” was put in square brackets indicating that a GRE decision/discussion is needed.

7. At the beginning of the meeting, CEMA and CLEPA experts asked to come back to Chapter 6.2 with regard to the installation height of additional dipped beam headlamps. It was proposed to increase the height to more than 3 m. The conclusion was to keep the decision taken during the 2nd session. CEMA and CLEPA were invited to prepare, if need be, an informal document with a proposal and a justification for discussion within GRE.

8. As agreed in the 2nd session, DE made a proposal to improve the wording concerning the installation height of 4 m to avoid that the maximum height of the vehicle exceeds 4 m due to the frame of the lamps as follows:

“Lamps shall be installed in such a way that the vehicle complies with applicable (national of regional) legislation concerning its maximum height.”

This proposal was accepted and was included in Chapter 5.8 of AVLI-01-03/Rev2b.

9. As also agreed in the 2nd session, Dr. Karl Manz made a proposal concerning the installation of the reversing lamp(s) and minimum requirements to avoid glaring. The proposal was discussed and slightly amended to read (See also AVLI-03-05):

“However, if the shape, structure, design or operational conditions of the vehicle makes it impossible to keep the lamp within 1,200 mm it is allowed to increase the height up to 4,000 mm.

In the latter case the lamp shall be installed with an downwards inclination of at least 3° for a mounting height larger than 2,000 mm and not more than 3,000 mm and at least 6° for a mounting height larger than 3,000 mm and not more than 4,000 mm.

No inclination is needed for mounting height up to 2,000 mm."

This proposal was accepted and was included in Chapter 6.4.4.2 of AVLI-01-03/Rev.2b.

10. Furthermore it was agreed to delete the Chapter 6.22 (Emergency Stop Signal) as this signal makes only sense at high speeds above at least 50 km/h in conjunction with strong dynamic behaviour at very high deceleration values (e. g. > 4,5 m/s2 for N2, N3 and > 6 m/s2 for M1). It could therefore only be acceptable under the same conditions as for N2, N3. In addition, there is a formal problem that R 13 resp. R 13 H which provide the necessary control signal are not applicable to tractors.

11. Also deleted was Chapter 6.23 (Signalling Panel) in the first step as signalling panels are mainly important for trailers and towed machines. Panels (Component) will be covered by R 70, the material used for the panels in R 104 (see also documents ECE-TRANS-WP29-GRE-2013-64e and ECE-TRANS-WP29-GRE-2013-65e). As a consequence, Annexes 6 and 7 have been deleted as well.
