This informal document aims at correcting and clarifying the draft amendments to Regulation No. 110 as proposed in WP.29/2013/101. At its November 2013 session, the World Forum WP.29 is expected to consider and adopt draft Supplement 1 to the 01 series of amendments to Regulation No. 110, inserting new provisions for motor vehicles using Liquefied Natural Gas (LNG) in their propulsion system. During the last session, GRSG agreed to have a final review of the proposal.

Proposal to align the definition of the “driver’s ocular points” with that of Regulation No. 125 (forward vision) as also used in EC Directive 2003/97/EC as amended by Directive 2005/27/EC.

OICA counter-proposal to the German proposal (document GRSG/2013/27) to introduce more stringent requirements for rear underrun protection devices.

Proposal to adapt the provisions for multi-function displays to technological progress. In principle, current displays can convey more information to the driver, including levels of severity or importance, while the current text was written when technologies were less flexible. As a result, the current provisions risk impeding the use of beneficial multi-function tell-tales.

Proposal to refine the text of document GRSG/2013/23 wherein Germany proposed to clarify the provisions on the extended field of vision of heavy goods vehicles across different mirror classes. The text would require assessment of normal and extended fields of vision using a single mirror adjustment and to allow for the loss of up to 10% of the close-proximity field of vision in such configurations. The UK proposes to add the word “simultaneously” in several places to confirm that the mirror can not be re-adjusted during the approval test in order to meet the extended field of view requirements.

Justification for raising the stringency of rear underrun protection device requirements as proposed in document GRSG/2013/27.

Proposal to clarify the “resistance to high temperature” test procedure to account for the effect of higher altitudes (barometric pressure) on temperature calibrations (e.g., the boiling point of water).

Presentation in support of and offering revisions to Japan’s proposal (document GRSG/2013/5) for amendments to UN R46 in order to bring the regulation into line with Japanese regulations (pursuant to the International Whole Vehicle Type Approval initiative).

CLCCR recommendation to establish an expert group to further consider the German proposal to raise rear underrun protection device (RUPD) requirements. CLCCR raises concerns over the cost-benefit and in particular, over the relative effectiveness of higher requirements across the range of vehicle categories that would be affected.

The informal group on camera-monitor systems (CMS) produced a proposal to enable the use of CMS as an alternative to conventional mirrors (document GRSG/2011/23/Rev.1). A decision on this proposal has been pending while the Forum awaits the establishment of an ISO standard on CMS. Since the ISO standard is now in its final stages, Germany proposes to reactivate the CMS informal group in order to prepare an updated regulatory proposal for these systems.

Proposal to require automatic mirrors to unfold automatically when the vehicle reaches a speed higher than 10 km/h. The concern is to address certain mirrors designed not to unfold at speeds up to 45 km/h.

Proposal to clarify that the requirements and test procedures introduced for fuel rails in the 01 series are not intended to apply to other CNG components.
