ECE R118 Annex 9 – Determination of the Resistance of Materials to Fuel or Lubricant
Our test laboratory performs accredited testing according to ECE R118 Annex 9. The test is used to evaluate the behaviour of non-metallic materials and components when exposed to fuels, lubricants, and comparable operating media. It is particularly applied to materials used in the interiors of buses, commercial vehicles, and other vehicle categories.
The regulation is especially relevant for materials and components that may come into contact with operating fluids in passenger compartments or adjacent areas, such as floor coverings, trim materials, insulation materials, textile fabrics, coated materials, as well as other non-metallic materials and composite structures in the automotive and commercial vehicle sector. ECE R118 is an essential part of international vehicle approval and type certification, for example for buses of categories M2 and M3.
The accredited testing laboratory of FILK is a designated Technical Service of Category A recognized by the German Federal Motor Transport Authority (Kraftfahrt-Bundesamt, KBA). Our services are recognized by leading manufacturers such as Daimler Buses & Trucks and MAN.
Test Principle and Procedure
In the ECE R118 Annex 9 test, defined test media such as fuels or lubricants are applied to the material surface under specified conditions. It is then evaluated whether and to what extent the liquids are absorbed by or penetrate the material.
The assessment particularly includes:
• resistance to fuels and lubricants,
• absorption and penetration behaviour of liquids,
• changes in surface or material structure after exposure to media,
• suitability of materials to limit the ingress of flammable liquids.
The test is used to assess material suitability under safety-relevant operating conditions in vehicles. It complements the fire safety tests according to ECE R118 Annex 6 to 8 and forms part of the overall safety assessment of materials and components in the commercial vehicle and bus sector.
