Submission for the October GRE session listing the Stage One and Stage Two amendments under development.

Currently under UN R48, it is possible to have additional contributors for driving-beam (more than four) in relation with AFS requirements (Par. 6.22.4.1.2.). This proposal is intended to extend such a possibility to driving-beam without AFS (Par. 6.1.). Brightness will be always limited by the requirements in Par. 6.1.9.1. (Imax value 430,000 cd for all driving-beam headlamps switch ON simultaneously). In case of additional modules, the surface of the driving-beam will increase and its luminance will decrease. Consequently, an oncoming driver would not receive any additional glare.

For light sources with integrated electronics an “Electronic light source control gear” comprises components between the supply and the light emitting elements. The definition was derived from IEC and CIE, where a light source is the light emitting element. Provisions for “Electronic light source control gear” are normally used in installation and device regulations, but create confusion in relation to light sources with integrated electronics. Therefore, it is proposed to tune this term to the use in installation and device regulations and no longer specifically mention integration (or not) in the light source; “Electronic light source control gear” is not defined in R.E.5., but is part of the light source definition. The proposal also delete the term “igniter” because it is not used in the regulation.

Proposal to correct an error introduced by the 01 series of amendments to UN R113 when angular coordinates were introduced instead of dimensions in mm with screen at 25 m. The same correction applies to the 02 and 03 series of amendments to UN R113 and to UN R149. The proposal also corrects Annex 3, Figure C of UN R113 where the description of the zone 1 is not in line with the photometric requirements set in paragraph 6.2.5.2. which defines the horizontal angles to 5° to the left and 5° to the right. Similarly, the proposal corrects Annex 4, Figure A4-IX of UN R149 where the description of the zone 1 is not in line with the photometric requirements set in paragraph 5.4.4.2. Table 34 which defines the horizontal angles to 5° to the left and 5° to the right for the class BS headlamps.
