Proposal to update document GRE/2016/34. At the 73rd GRE session, France proposed to delete a design restrictive requirement (GRE/2015/22 and GRE-73-26). This proposal received comments from Germany and the Netherlands. Poland suggested a different approach on this issue (GRE-73-21). The Chair invited France, Germany, Netherlands, Poland, CLEPA and IEC to prepare a revised proposal for the next session. Based upon the approach proposed in GRE/2015/22 and GRE-73-26, GTB has investigated the specification of minimum levels of flux projected in critical zones of the passing beam distribution. This approach offers a technology-neutral performance based requirement. The result of the GTB study is to propose minimum projected flux requirements in two zones:
a) 15°D-1°U/30°L-30°R to ensure overall adequate illumination of the road and
b) 3.5°D-1°U/30°L-30°R to ensure sufficient range.

Exchange of communications between the secretariat and the UN Office of Legal Affairs concerning the simplification of lighting and light-signalling Regulations (SLR). GRE proposed to consolidate around 30 Regulations on different individual lighting and light-signalling devices (lamps) into three new Regulations (forward lighting, light-signalling, and retro-reflective devices). OLA provides general comments in response to GRE questions intended to ensure that the selected approach respects the legal and administrative requirements of UN treaties and specifically the 1958 Agreement.

Analysis raising concerns regarding the proposal to establish photometric requirements for Class B1 based on average real performance of present Class B (halogen/LED) without reference to design specifications such as the luminous flux of light source.

Presentation concerning the proposal to introduce a new optional “Class B1” headlamp.

Proposal to introduce a new optional “Class B1” headlamp. The proposal would establish photometric requirements for Class B1 based on average real performance of present Class B (halogen/LED) but would not include additional design restrictions such as the luminous flux of light source.
