ECE-R-10
UNECE Regulation No. 10 (ECE-R-10) specifies the electromagnetic compatibility (EMC) requirements for vehicles and their electrical and electronic components. It is a mandatory framework for type approval in many countries, especially in the European Union.
Scope and Application
ECE-R-10 applies to vehicles of classes M, N, O, L, T, and S and to electronic sub-assemblies (ESAs) with independent electrical functions. It covers both whole vehicles and components that are intended to be installed in vehicles. Compliance is required for ECE type approval and is recognized in many global markets outside the EU.
Key Technical Requirements
Emission limits: Radiated and conducted emissions must remain below defined thresholds.
Immunity: Devices must maintain functionality under defined electromagnetic disturbances.
Wireless communication: Systems such as radar, cellular modules, and GNSS are subject to specific tests.
OBD-related testing: Specific requirements apply to on-board diagnostics during EMC testing.
Testing is conducted according to Annex 6 (component level) and Annex 7 (vehicle level) of the regulation, with reference to international standards such as ISO 11452 and CISPR 25.
Certification and Compliance
The EMC performance must be assessed and approved by a technical service designated by an approval authority. The resulting EMC test reports form part of the official type approval documentation. A valid ECE approval mark is issued once compliance is confirmed.
Lifecycle Relevance
ECE-R-10 plays a role throughout the product lifecycle:
Pre-compliance testing during development
Final type approval before production
Requalification after design or software modifications
Relation to Other Standards
ECE-R-10 complements the EMC Directive (2014/30/EU) for automotive components and interfaces with the Radio Equipment Directive (2014/53/EU) when wireless technologies are used. It is especially relevant for Automotive Radar, Bluetooth, and GNSS-enabled systems in vehicles.
