ECE R10 is a regulation published by The United Nations Economic Commission for Europe (UNECE) for automotive industry. UNECE has 56 member states as of 18 February 2020. ECE R10 is defining Electromagnetic Compatibility requirements of the vehicles and electronic sub assemblies (ESAs) used in automotive.


As given on the scope of ECE R10, the regulation applies to:

1.1. Vehicles of categories L, M, N O, T, R and S1 with regard to electromagnetic compatibility;

1.2. Components and separate technical units intended to be fitted in these vehicles with the limitation given in paragraph 3.2.1. with regard to electromagnetic compatibility.

1.3. It covers: (a) Requirements regarding the immunity to radiated and conducted disturbances for functions related to direct control of the vehicle, related to driver, passenger and other road users’ protection, related to disturbances, which would cause confusion to the driver or other road users, related to vehicle data bus functionality, related to disturbances, which would affect vehicle statutory data; (b) Requirements regarding the control of unwanted radiated and conducted emissions to protect the intended use of electrical or electronic equipment at own or adjacent vehicles or nearby, and the control of disturbances from accessories that may be retrofitted to the vehicle; (c) Additional requirements for vehicles and ESAs providing coupling systems for charging the REESS regarding the control of emissions and immunity from this connection between vehicle and power grid.


    Version of ECE R10 is mentioned as ECE R10 Rev.6ECE R10 Rev.5 or ECE R10 Rev.4The latest version is Revision 6 and it has been officially published by UN ECE. On 30 October 2020, United Nations published an amendment for ECE R10 Rev.6. ECE R10 regulations and its amendments are free documents, you can download them by visiting official website of UN ECE. However, you can not reach test standards mentioned in the regulation since most of the test standards are not free of charge. If you need to check the details of standards you have to purchase them from web store of the standard publisher. Alternatively, you can ask Testups any technical questions about the tests.

    UN ECE R10 explains how to perform EMC tests and there are various test standards that are applied. Each test and test setup is explained in detail. UN ECE R10 EMC Tests can be categorized into two groups: emission and immunity. Emission and immunity tests are performed according to referred test standards. The standards referred to UN ECE R10 Revision 6 are listed below:

    CISPR 12, CISPR 16-1-4, CISPR 25, ISO 7637-2, ISO-EN 17025, ISO 11451, ISO 11451-1, ISO 11451-2, ISO 11451-4, ISO 11452, ISO 11452-1, ISO 11452-2, ISO 11452-3, ISO 11452-4, ISO 11452-5, ITU Radio Regulations, edition 2008, IEC 61000-3-2, IEC 61000-3-3, IEC 61000-3-11, IEC 61000-3-12, IEC 61000-4-4, IEC 61000-4-5, IEC 61000-6-3, CISPR 16–2–1, CISPR 22, CISPR 16-1-2, IEC 61851-1 and CISPR 32.

    What are immunity related functions?

    ECE R10 mentions immunity related functions of the vehicle. This defines the test plan since products with immunity related functions need much more testing. “Immunity related functions” are listed as six function categories. This list is not exhaustive and shall be adapted to the technical evolution of vehicle or technology. 

    1) Functions related to the direct control of the vehicle: 

    • By degradation or change in: e.g. engine, gear, brake, suspension, active steering, speed limitation devices;
    • By affecting drivers position: e.g. seat or steering wheel positioning;
    • By affecting driver’s visibility: e.g. dipped beam, windscreen wiper, indirect vision systems, blind spot systems.

    2) Functions related to driver, passenger and other road user protection: 

    • E.g. airbag and safety restraint systems, emergency calling systems; 

    3) Functions which, when disturbed, cause confusion to the driver or other road users: 

    • Optical disturbances: incorrect operation of e.g. direction indicators, stop lamps, end outline marker lamps, rear position lamp, light bars for emergency system, wrong information from warning indicators, lamps or displays related to functions in subparagraphs (a) or (b) which might be observed in the direct view of the driver; 
    • Acoustical disturbances: incorrect operation of e.g. anti-theft alarm, horn. 

    4) Functions related to vehicle data bus functionality: 

    • By blocking data transmission on vehicle data bus-systems, which are used to transmit data, required to ensure the correct functioning of other immunity related functions. 

    5) Functions which when disturbed affect vehicle statutory data: e.g. tachograph, odometer; 

    6) Function related to charging mode when coupled to the power grid: 

    • For vehicle test: by leading to unexpected vehicle motion; 
    • For ESA test: by leading to an incorrect charging condition (e.g. over-current, over-voltage).

    How to apply ECE R10 tests?

    EMC tests are performed according to relevant clauses of ECE R10 regulation at EMC testing laboratories. EMC testing laboratories which are able to perform ECE R10 tests, are equipped with IEC, ISO or CISPR compliant EMC test chambers and equipments. Test experts check the product features and functions and make a test plan according to applicable ECE R10 EMC tests. Emission and immunity tests are performed. As Testups offers, ECE R10 tests can be finished in 4 weeks, if the product passes all product-specific EMC tests listed on the regulation and referred standards. After passing all applicable ECE R10 tests, test report is issued for the product (vehicle or ESA). This test report shows the ECE R10 test results of the product and it is required if the product also needs ”E-mark” or type approval according to UN ECE R10.


    After ECE R10 tests are done and PASS test report issued, Type Approval or Homologation (E-marking) can be also issued for the product. In this step, ECE R10 test report, technical documents of the product and quality documents (like valid ISO 9001 certificate) of the manufacturing or/and distributor company are checked by a third party and authorized agency. They are also called designated technical service. If all product and company documents are submitted properly, E mark including a unique number can be affixed or labeled on the product.

    Examples of approval marks

    The below approval mark affixed to a vehicle or ESA shows that the vehicle type concerned has, with regard to electromagnetic compatibility, been approved in the Netherlands (E 4) pursuant to Regulation No. 10 under approval No. 05 2439. The approval number indicates that the approval was granted according to the requirements of Regulation No. 10 as amended by the 06 series of amendments.
