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.

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.

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.

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

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.

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?

Pending requests and future items for changes to UN R55.

Proposal as developed by the UN R55 informal group during its 12th session. This proposal concerns a procedure to identify allowable combinations of performance values Dc and V for drawbar coupling equipment. This proposal would amend the Revision 2 proposal for UN R55.

Revised proposal developed by the UN R55 informal group to introduce provisions for mechanical couplings used in modular vehicle combinations (e.g., rigid truck + dolly + semi-trailer) presently not addressed within the regulation.

Proposed text for determining worst case conditions for physical testing of couplings.

Informal group schedule for finalizing amendments to update UN R55.

Revised version of document GRRF-80-41 pursuant to the 12th UN R55 informal group session. GRRF-80-41 was the revised formal proposal to 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.

During its first session, the EMC Task Force considered proposal regarding the application of UN R10 to trolley buses (under UN R107), to UN R46 (indirect vision and camera monitor systems), and to the work on automatic emergency call systems (AECS), as well as a proposal to amend UN R10 itself. OICA provides the views of its EMC experts in this document.
