UN R118 — Burning behaviour of vehicle interior materials
Consider a material’s behaviour together with where it is used in the vehicle.
Explore the scopeWhat does it cover?
UN R118 addresses ignition, burning rate and melting behaviour of vehicle materials, as well as their ability to repel fuel or lubricant. This version focuses on M3 class II and III vehicles and also mentions class I at the manufacturer’s request. Vehicle type and component approval are covered separately, with distinctions for the interior, engine compartment, separate heating compartment and electrical cables.
Who is it for?
Bus manufacturers, interior-trim and insulation suppliers, and fire-safety testing teams.
Which subjects are addressed?
- Burning behaviour
- Repellence of fuel and lubricants
- Vehicle-type and component approval
- Cables and protective sleeves or ducts
Common question
Does a material certificate replace approval of the whole vehicle?
No. The regulation treats component and vehicle-type approval separately. The location of the material and the vehicle scope must also be assessed.
