Proposal as prepared by the UN R55 informal group and approved by the GRRF to update UN R55 with respect to:
a) Requirements on remote indication;
b) Availability of information on coupling fixing points for A50X couplings;
c) On lateral strength of drawbars; and
d) a new class definition for fully automatic drawbar couplings.

Proposal to clarify that fully integrated surveillance mirrors may be mounted below 2 metres in cases where they are integrated in a housing including one or more Class II or III mirrors.

Proposal to correct an oversight by aligning the “alternative procedures” provisions of the regulation with the previously adopted amendment of the regulation that raised the rear-impact speed to between 48 and 52 km/h (03 series of amendments).

This proposal clarifies that the provisions concern any cable used in the entire vehicle, not only to those in the interior compartment, engine compartment and separate heater compartment. The proposal also clarifies that the regulation applies not only to electric cables, but also to cable sleeves or cable conduits and it updates the reference to paragraph 5.22. of ISO 6722-1:2011. Specifically, the proposal would apply testing to electric cables, cable sleeves, and cable conduits that exceed a length of 100 mm.

Proposal to remove the provisions for welded constructions of compressed natural gas (CNG) cylinders or metal liners, including high-strength steel CNG cylinders and consolidating the earlier proposal (from document WP.29/2015/90 that was adopted but set aside at the November 2015 WP.29 session pending the proposal on cylinder construction) to regulate the discharge direction of pressure relief devices on CNG containers.

Proposal to modify UN R125 in line with the amendment to UN R46 (indirect vision) that introduces the use of camera-monitor systems (CMS) in place of rear-view mirrors. This proposal also ends the temporary exemption permitting CMS device obstruction of driver field of view from 1 September 2021.

Proposal to mandate fire suppression systems on Class I and II buses.

Proposal to

1. extend requirements for exterior rear-view mirrors to camera monitor systems;
2. reduce the speed threshold for deactivation of emergency controls from 5 km/h to 3 km/h;
3. clarify the requirements concerning the height of steps in vehicles which comply with Annex 8;
4. limit the mandatory application of the requirements for dedicated areas for prams and pushchairs to Class I vehicles;
5. require activation of the alarm and fire suppression systems as soon as the heater is in function regardless of whether the engine is operating;
6. extend requirements for exposed seats adjacent to step wells to apply to other exposed seats where there is a risk of the occupant being thrown forward; and
7. correct the text of the Regulation.

Proposal to

• extend requirements for exterior rear-view mirrors to camera monitor systems;
• reduce the speed threshold for deactivation of emergency controls from 5 km/h to 3 km/h;
• clarify the requirements concerning the height of steps in vehicles which comply with Annex 8;
• limit the mandatory application of the requirements for dedicated areas for prams and pushchairs to Class I vehicles;
• require activation of the alarm and fire suppression systems as soon as the heater is in function regardless of whether the engine is operating;
• extend requirements for exposed seats adjacent to step wells to apply to other exposed seats where there is a risk of the occupant being thrown forward; and
• correct the text of the Regulation.

Proposal to allow for small variations in the presentation of motorcycle telltales and control symbols.

Correction of the French text only of the 01 series of amendments to UN R73.

Chronology summarizing the discussions held on agricultural coupling requirements under UN R55 since 2011.

Proposal to allow for a vertical load up to 80 kg for drawbar coupling designs with a jaw that pivots about the horizontal transverse axis because such configurations are commonly used in fire trucks and other special use vehicles in Germany, Austria and Switzerland.

One of the outcomes of the work on updating UN R55 was the recognition that agricultural couplings present a set of challenges distinct from other vehicles. Therefore, Germany proposes the establishment of an informal working group to develop a new regulations (UN R55-A) to respond to the specific needs of agricultural vehicle couplings.

Proposal from the informal group on UN Regulation No. 55 to introduce provisions for coupling applications in multi-vehicle combinations ( e.g. rigid truck + dolly + semi-trailer) presently not addressed by the regulation.

Quick review of the informal group’s anticipated schedule for completing its work on updating the regulation on mechanical couplings.

Further refinements from the informal group on UN Regulation No. 55 to introduce provisions for modular vehicle combinations (e.g., rigid truck + semi-trailer + dolly). This proposal concerns a procedure to identify allowable combinations of performance values Dc and V for drawbar coupling equipment.

Working draft of the regulation pursuant to the 11th AECS informal group session.

Request for task force views with regard to the work on automatic emergency call devices (AECD):

1. Does R10.04 (and any later version) fully cover the EMC aspects for AECD components to be fitted to vehicles and for vehicles with these systems installed/integrated?
2. If not, what amendments can be proposed to Regulation 10?
3. Are specific EMC provisions necessary within the Regulation on AECS?
