Proposal to insert new paras. 3.3.29. to 3.3.33. defining “Semi-Metallic-Organic,” “Low-Steel-Organic,” “Non-Asbestos-Organic,” and “Low-Steel-Non-Organic” friction materials and “Pad area,” amend Annex 2 title to read “Annex 2 Communication,” insert a new footnote to Annex 2, and insert a new Annex 2 – Appendix containing a list of vehicle data for UN Regulation No. [XXX] approvals including vehicle type description, brake linings and discs specifications, vehicle test mass, maximum speed, tyre dimensions, brake circuit configuration, and brake specifications.
This document proposes a new UN Regulation on uniform provisions concerning approval of non-original and identical replacement brake parts regarding particulate emissions. The regulation applies to laboratory measurement of brake emissions from non-original replacement brake pads, linings, discs, and drums for vehicles of categories M₁, N₁, and N₂ originating from vehicles with type approval under Regulation No. 179. Approval requires emission factors to comply with specified limits based on vehicle category and powertrain technology. The regulation establishes brake emissions families based on characteristics including calliper type, vehicle axle location, friction material formulation, brake disc or drum material, disc surface form, friction material surface area, and drum diameter. Testing procedures, conformity of production requirements, marking and packaging specifications, and approval extension procedures are detailed.
