Session 76 | Geneva | 17-21 Feb 2014
5. (a) Regulation No. 78
GRRF/2014/5 | Proposal for amendments to Regulation No. 78 Proposal from the International Motorcycles Manufacturer Association (IMMA) to introduce amendments clarifying the current text on the use of Combined Braking Systems (CBS) into UN R78.
GRRF/2014/6 | Proposal for amendments to Regulation No. 78 Updated proposal for a series of amendments to clarify a variety of requirements, notably concerning test surface requirements, ABS cycling, and peak braking coefficient measurements under UN R78.
GRRF-76-19 | Comments from the Netherlands on the document GRRF/2014/6 (concerning UN R78 on motorcycle braking) Explanation of Dutch concerns with the IMMA proposals on the measurement of brake efficiency and the use of a representative vehicle for testing.
GRRF-76-32 | India’s Comments on documents GRRF/2014/4 and /5 India supports the purpose of the amendments to GTR No. 3 (GRRF/2014/4) and UN R78 (GRRF/2014/5) to provide same safety in the case of a failure in CBS as that of the conventional system of the two independent brakes for two wheelers. However, India believes the application of the amendments to three-wheelers requires additional consideration. Therefore, in order to proceed with amendments concerning CBS for two-wheelers, India proposes changes to the proposed text in order to allow further consideration of three-wheelers.
GRRF-76-36/Rev.1 | Proposal for amendments to ECE/TRANS/WP29/GRRF/2014/5 Proposal to clarify the intent of the selected paragraphs to ensure that systems with with one service brake meet braking performance requirements using only that brake system (i.e, without any assistance from the secondary brake system). There had been an interpretation that for systems with two service brakes each brake had to meet the requirements which would result in higher stringency levels than intended by the requirement for single brake systems. The proposal also clarifies the parts of the braking system that should be considered with respect to hydraulic brake and mechanical transmissions and further clarifies that the test procedures are designed to simulate a brake failure rather than produce one.
GRRF-76-45 | Proposal for amendments to Regulation No. 78 Proposal to clarify provisions on the use of Combined Braking Systems (CBS) and make some additional editorial improvements. This document contains GRRF/2014/05, GRRF/2014/06, GRRF-76-36 Rev 1 and updated by the comments raised at the seventy-sixth GRRF session.
12. (b) Revision and extension of approvals
GRRF/2013/31 | Proposal for collective amendments to Regulations Nos. 13, 13-H, 30, 54, 55, 78, 79, and 90 Text prepared by the International Organization of Motor Vehicle Manufacturers (OICA) to introduce the concept of "revision of approvals" into the UN Regulations under GRRF responsibility in order to align the UN Regulations with the EU Whole Vehicle Type Approval Directive 2007/46/EC in order to ease the administrative burden for both manufacturers and approval administrations regarding the extension of existing approvals.
