Submitted by Poland to replace document GRE/2012/27 proposing an alternative set of requirements for the initial aiming of dipped-beam headlamps and allowing to remove the artificial 2,000 lm borderline and Light Emitting Diode (LED) automatic levelling.
9. The Expert from Poland introduced ECE/TRANS/WP.29/GRE/2012/27 proposing to remove the present 2000 lm borderline and the Light Emitting Diodes (LED) automatic levelling requirement. The proposal received several comments (GRE-68-20, GRE-68-31, GRE-68-32 and GRE-68-34).
10. GRE agreed with the suggestion of the expert from the Netherlands to concentrate requirements only on the “initial aiming” (and leave out the other parts on labelling, photometrics, etc.). It was also suggested that the proposal would focus on possible overlaps to the headlamp mounting height and would consider this “new approach” for the initial aiming requirements as an alternative to the existing (“old approach”) requirements in UN Regulation No. 48. GRE agreed to resume consideration of this subject at its next session on the basis of a revised proposal tabled by the expert from Poland including the suggestions mentioned above.
11. GRE noted that the World Forum (WP.29) referred back ECE/TRANS/WP.29/2011/99 and Corr. 1 for further consideration. GRE agreed to resume consideration of this subject at its April 2013 session. The expert from GTB introduced GRE-68-38, GRE-68-39 and GRE-68-40 providing a status report of the GTB’s activities on Glare and Visibility
12. The expert from Poland introduced ECE/TRANS/WP.29/GRE/2013/15 proposing an alternative to the existing initial aiming provisions. The experts from France and the United Kingdom requested the author to clarify the aspect linked to the measurements and to specify the measurement method as well as the tools to be used. The expert from the Netherlands supported, in general, the proposal but questioned waiving automatic levelling as an incentive to use this alternative method. GRE agreed to resume consideration on this matter at its October 2013 session on the basis of an updated proposal prepared by the expert from Poland in collaboration with experts from France, the Netherlands and the United Kingdom.
12. The expert from Poland presented GRE-70-41, introducing ECE/TRANS/WP.29/GRE/2013/57 and proposing performance based requirements on initial aiming of dipped-beam headlamps as an alternative to the existing requirements. The proposal received some comments (GRE-70-42). The expert from France requested adding proper tolerances from the Conformity of Production provisions. GRE agreed to revisit this subject (on initial aiming and considering the original 50 m visibility distance requirement) at its next session on the basis of a revised document, which the expert from Poland volunteered to prepare.
