ECE R10 is a United Nations Economic Commission for Europe regulation that establishes uniform provisions concerning the approval of vehicles with regard to electromagnetic compatibility (EMC).

What vehicles does ECE R10 apply to?

ECE R10 applies to motor vehicles including motorcycles, passenger cars, commercial vehicles, and their electronic sub-assemblies (ESAs) with regard to electromagnetic compatibility.

How does ECE R10 affect motorcycle key systems?

ECE R10 affects motorcycle key systems by setting EMC requirements for immobilizers, key fobs, and electronic control units to ensure they don't interfere with vehicle systems and can operate in electromagnetic environments.

What are the key EMC requirements?

Key EMC requirements include emission limits for radiated and conducted disturbances, immunity to electromagnetic fields, electrostatic discharge, and transient disturbances according to specified test methods.
