In response to concerns that approval agencies may not grant manufacturers the additional 1dB for L(wot) on conformity of production tests as changes had been made to Annex 6 of R41-04, GRB issued an interpretation recorded in the report of its 56th session. However, IMMA believes that industry and agency personnel may still not be aware of the interpretation. Therefore, IMMA proposes to codify the interpretation within UN R41.

The purpose of this proposal is to update the reference to the latest version of the ISO 10844 and to introduce transitional provisions for the shift of the test track requirements from ISO 10844: 1994 to ISO 10844: 2014. This proposal supersedes document GRB/2015/5.

Proposal to require proof of electromagnetic compatibility through compliance with UN R10 or any other equivalent test as may be agreed between the manufacturer and test service.

Proposal to delete the angle of incidence provision that was developed to ensure that the vehicle registration plate is illuminated. Given current technologies (e.g., LED lamps), the performance requirements of Annex 5 can be met without reference to the angle of incidence.

Proposal to introduce a definition for “twinned wheels”.

Proposal to allow for small variations in the presentation of motorcycle telltales and control symbols that do not deviate to such an extent as to cause confusion.

IMMA comments on the EC revised draft text for the GTR on motorcycle evaporative and crankcase emissions (document EPPR-11-14).

In response to concerns that approval agencies may not grant manufacturers the additional 1dB for L(wot) on conformity of production tests as changes had been made to Annex 6 of R41-04, GRB issued an interpretation recorded in the report of its 56th session. The proposal formalizes the interpretation as an explicit provision of the regulation.

Proposal to clarify the electromagnetic compatibility requirements under UN R78 with regard to the application of UN Regulation No. 10.

Proposal to introduce a definition for “twinned wheels”.

Proposal to delete the angle of incidence provision that was developed to ensure that the vehicle registration plate is illuminated. Given current technologies (e.g., LED lamps), the performance requirements of Annex 5 can be met without reference to the angle of incidence.

Proposal to enable the approval of emergency stop signal on motorcycles to increase safety.

Proposal to enable the approval of sequential activation of light sources of direction indicators lamps for motorcycles.

Proposal to allow the use of different brake lamp activation methods and to align the brake lamp provision with those applicable for four-wheelers.

Proposal to allow for the installation on motorcycles of light-signalling devices with light sources that can be sequentially activated.

Proposal to delete references to UN R113 Class B headlamps from the regulation.

Correction of two minor reference errors contained in the proposal for Supplement 2 to the 04 series of amendments to Regulation No. 41 which was adopted during the March 2015 session of WP.29.

Proposal to specify that conditioning of exhaust or silencing systems is required only in cases where the fibrous materials are in contact with exhaust gases because there is no possibility for the dispersion of fibrous materials under any other condition.

Documents GRRF/2015/40 and 41 propose to align GTR 3 and UN R78 with the provisions for anti-lock braking systems used in other regulations. The proposal clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle. IMMA wishes to make the wording more technology-neutral, clarify test conditions considered impractical, and allow time for manufacturers to comply (i.e., add transitional provisions).

IMMA presentation regarding the intention to propose emergency stop signal (ESS) provisions to UN R78 and GTR No. 3. ESS, which automatically activates hazard warning lights during forceful braking situations, already exists under UN R13-H for cars and trucks. IMMA has submitted document GRE-2015-40 to similarly amend UN R53.

The current text of UN R41 provides an allowance that increases the noise limit value by 1 dB(A) for motorcycles tested only in second gear under Annex 3. This allowance expires on 1 January 2017. IMMA proposes to extend this allowance until 1 January 2018 in response to the delayed implementation of UN R41-04 in the EU (2016 instead of planned 2014).

Revised proposal, taking into account comments from the previous GRSG session, to allow for small variations in the presentation of motorcycle telltales and control symbols that do not deviate to such an extent as to cause confusion.

Revised proposal to delete in Regulation No. 53 the references to headlamps of Class B of Regulation No. 113.

Proposal to allow Emergency Stop Signal (ESS) systems on motorcycles and related vehicles.
