ECE R10, Regulation 10, R10 or UNECE R10 is one of the automotive regulations published by The United Nations Economic Commission for Europe (UNECE) which has 56 member states as of 18 February 2020. ECE R10 is defining Electromagnetic Compatibility (EMC) requirements of the vehicles and electronic sub assemblies (ESAs) used in automotive. It defines EMC requirements (tests and type approval) of the products (vehicles, electronic components and systems) 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.

    ECE R10 Rev.7 is not published yet. When Revision 7 of UNECE R10 published you will see the differences on this page. 


    ECE R10 is not the only regulation published by UN ECE. There are  160 regulations published by UN ECE. Each regulation specify requirements of the different types of vehicles or components that will be used on that vehicles.

    UNECE 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: emissions and immunity. Emissions and immunity tests are performed according to referred test standards. The standards referred to UNECE 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. These test standards are showing the test setup, level and limit details which are not given under ECE R10. 

    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 EMC 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. Emissions and immunity tests are performed. As Testups offers, ECE R10 EMC 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, EMC 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. Of course, if the product tested fails any EMC tests, product designer or manufacturer should modify it or send a new sample to be tested. 


    After ECE R10 EMC tests are done and PASS test report issued, Type Approval Certificaition or Homologation (E-marking) can be also issued for the product. In this step, ECE R10 test report, technical documents of the product, Conformity of Production (CoP) inspection report/certificate, 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 issued and submitted properly, E mark including a unique number can be affixed or labeled on the product.

    An approval number is assigned to each type approved. The type approval number consists of 4 sections. Each section shall be separated by the ‘*’ character.

    Section 1: The capital letter ‘E’ followed by the distinguishing number of the Contracting Party which has granted the type approval.

    Section 2: The number of the relevant UN Regulation, followed by the letter ‘R’, successively followed by:

    (a) Two digits (with leading zeros as applicable) indicating the series of amendments incorporating the technical provisions of the UN Regulation applied to the approval (00 for the UN Regulation in its original form);

    (b) A slash and two digits (with leading zeros as applicable) indicating the number of supplement to the series of amendments applied to the approval (00 for the series of amendments in its original form);

    (c) A slash and one or two character(s) indicating the implementing stage, if applicable.

    Section 3: A four-digit sequential number (with leading zeros as applicable). The sequence shall start from 0001.

    Section 4: A two-digit sequential number (with leading zeros if applicable) to denote the extension. The sequence shall start from 00.

    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.

    Unique Identifier (UI)

    UNECE, with its E/ECE/TRANS/505/Rev.3, allows an alternative marking, called Unique Identifier (UI), showing the type approval. For this, this requirement shall be satisfied:

    If the type approvals applicable to a wheeled vehicles, equipment or parts are stored on the secure internet database, then the approval markings required by UN Regulations may be replaced by a Unique Identifier (UI) preceded by the symbol (UI), unless specified otherwise in the UN Regulations. Such unique identifier shall be generated by the database automatically.

    UI marking, is assumed to solve complexity of several E markings of a type which falls under the scope of more than UNECE Regulations.


    Applicable EMC tests according to UN ECE R10 for the vehicles depend on the features of the vehicle tested. Radiated emissions tests are applicable for all vehicle types. Radiated immunity tests are applicable for vehicles having immunity related functions. Other EMC tests are applicable for electrical vehicles which can be charged via AC or DC power. Here is a brief summary list of EMC tests applicable for the vehicles: 

    Which countries are covered by ECE R10?

    There are 57 countries which are under the scope of UN ECE Regulation 10. Each country has a ECE symbol and designated type approval authority. For instance for Ireland, ECE symbol is E24 and designated type approval authority is NSAI. For whole list of ECE R10 countries visit this page: ECE R10 Countries


    There are two cost item for ECE R10 compliance: testing and type approval. 

    What are the costs for ECE R10 EMC testing?

    EMC testing costs depend on the features of the product, test plan, and location of test laboratory.  If your product is a simple electronic sub assembly which has no immunity related function, reduced EMC tests are allowed. This will make costs lower. For such a simple product operating at a single voltage and with a single operation mode, ECE R10 testing costs will change in this range: 3.000 – 3.500 USD. 

    What are the costs for ECE R10 Type Approval?

    Type approval costs depend on the agency or country issuing the type approval.  Although E1(Germany) and E24(Ireland) marks are technically identical, E1 marking takes some much more time and a bit expensive than E24 due to authorized agency costs. ECE R10 type approval (E marking) costs will change in this range: 1.500 – 2.000 USD.

    How to reduce ECE R10 testing costs ?

    If you are suffering from the costs for ECE R10 testing and type approval, take into account suggestions listed below: 

    • Check ECE R10 EMC tests during the design stage of your products. Early testing would save you time and money since you would have opportunity to get test results before serial production.
    • Use same or similar electronic components when designing your products. Using similar electronic components would increase the probability of the PASS ratio of test results. If you use various types of electronic components, ensure that they have been EMC tested or certified.
    • Group similar products in terms of electromagnetic compatibility and reduce number of model names with product family names. ECE R10 allows product grouping if technically applicable. When defining your product model names, try to group them under a product family model names.
    • Start testing with pre-compliance EMC tests during design validation stage of your products, this would save time and cost during ECE R10 certification. If an electronic product or vehicle never tested before, it would probably fail at one of ECE R10 tests. Pre-compliance testing would save you time and money even it seems causing extra costs.
    • Try to perform some EMC tests in house by having EMC test equipments (if you regularly need ECE R10 testing or type approval service). Work on investing on some of the EMC test instruments and prepare test setups which are most essential for your product. By in house testing, you would get opportunity to design your product more comfortable and to check your product’s EMC performance during its pilot or serial production.
    • Build a UN ECE R10 compliant EMC test laboratory (if you have various products that need ECE R10 testing or type approval service). UN ECE R10 compliant test laborotory needs some expert staff like test engineers and technicians. If your team can handle these laboratory operations, building a new test laboratory would make you much more comfortable in terms of electromagnetic compatibility of your products. If you would like go further, have accreditation or authorisation for your laboratory to show your lab’s independency and satisfy your customers.

    What is Conformity of Production (CoP)?

    The manufacturer is responsible for ensuring all the products manufactured, sold and registered in the applicable market conform to UNECE Regulation 10. CoP is a means of evidencing the ability to produce a series of products that exactly match the specification, performance and marking requirements outlined in the type approval documentation. Whether you are a manufacturer, or the agent applying for approvals on behalf of a manufacturer, and whatever your product is, suitable CoP arrangements must be made. Your CoP inspection report or certificate will be checked during the ECE R10 type approval certififcation. If this report or certificate is missing, you can have this service from an accredited body or from us. We are partnering with certification agencies who are capable of inspecting and issuing CoP certificate. 

    How to prepare for ECE R10 Certification?

    Four tips you should do prior to ECE R10 Certification of a product:

    1. Finalize design and prepare technical documents of the product

    2. Apply some pre-compliance EMC tests to your product (you can either perform some EMC tests in house or hire an EMC laboratory for pre-compliance EMC tests)

    3. Set a budget and time schedule for ECE R10 EMC tests and type approval certification

    4. Prepare whole document set (product, company, quality, conformity of production)

    If you consider above tips your ECE R10 certification process will be smooth.
