UN R117 establishes test procedures ensuring reliability, repeatability and reproducibility of results through standard reference test tyres manufactured by Manufacture Francaise des Pneumatiques Michelin in accordance with ASTM International standards. In 2024, the Russian Federation’s technical service was officially refused supply of these tyres due to export sanctions. The Russian Federation contends this refusal constitutes discrimination against a Contracting Party to the 1958 Geneva Agreement and calls on WP.29 to assess this discrimination and explain to the manufacturer its role in implementing the Agreement within the UN system.
