Meeting minutes documenting PMP discussions on amendments to Brakes GTR 24 and UN R179, including TF3a layout and testing topics, TF3b vehicles limited speed work, TF3c brake replacement parts with a new UNR to be introduced, and TF4 electromechanical brakes with no further progress. GTR and UNR informal documents on HD brakes were presented with trailers removed from scope, open points on PM Emission Factor units, caliper position, test input parameters, and cooling air flow value addressed, and a 3-month delay in round robin testing reported.

Editorial corrections to the Appendix and reference to Annex 4.

Overview of working documents for the 95th session of GRPE, listing five working documents on new GTR for heavy-duty brake emission, UN R179 second supplement, GTR 24 third amendment, vehicles with limited speed for UN R179 and GTR 24, and new UNR on emissions covering brake replacement parts, with informal documents to follow from clean working documents.

Progress report on development of a Global Technical Regulation for brake emissions testing. The document presents bracketed parameters under development including brake test temperature measurement, sampling plane positioning, brake enclosure dimensions, payload factors, and emission factor calculations. It outlines the structure of the informal document based on UN R179, defines endurance braking systems and electric regenerative braking, presents C-factor methodology for primary and secondary endurance braking, and describes conformity of production procedures and next steps including removal of brackets and round-robin data analysis.
