EU publishes UN brake-emission measurement rule for light-duty vehicle approvals

Vehicle manufacturers must use UN R179 brake-emission evidence for approvals

Change
The EU Official Journal published UN Regulation No 179 on laboratory measurement of brake emissions for light-duty vehicle approvals.
Why it matters
The publication fixes the laboratory measurement standard for brake-emission approval evidence. Vehicle manufacturers and type-approval teams must align brake-emission test files to UN Regulation No 179 when seeking approval for covered light-duty vehicles.
Implications
  • Light-duty vehicle manufacturers seeking approval must prepare brake-emission test evidence under UN Regulation No 179 instead of relying on non-aligned laboratory methods.
  • Type-approval teams must check whether brake-emission submissions for covered light-duty vehicles match the UN Regulation No 179 measurement provisions before approval files are lodged.
