Draft amendments to the proposal to improve and correct the procedure for measuring laboratory brake emissions on light-duty vehicles (GRPE/2026/30). The document establishes scope and application for vehicles of category M₁ and N₁, defines abbreviations and symbols, sets compliance requirements with emission limits for PM10, and specifies test procedures including cooling adjustment, brake bedding, and emissions measurement sections using the WLTP-Brake cycle. It addresses brake corner emission families, type approval requirements, conformity of production testing at least once every 12 months with statistical pass/fail decision charts, and conformity assessment through verification procedures.
