EN 55025 Vehicle EMC Immunity Testing: A Comprehensive Guide to Eurolabs Laboratory Testing Services

Standard-Related Information

EN 55025 is a European standard that outlines the requirements for vehicle electromagnetic compatibility (EMC) immunity testing. This standard is part of a broader set of regulations aimed at ensuring that vehicles do not emit electromagnetic interference (EMI) that can compromise the performance or safety of other electronic devices.

The relevant standards governing EN 55025 Vehicle EMC Immunity Testing include:

  • EN 55025:2018: Electromagnetic compatibility - Vehicles, motor boats and ships - Emission and immunity

  • ISO 11452-1:2017: Road vehicles - Component test methods for electromagnetic compatibility - Part 1: General requirements

  • IEC 61967-3:2004: Electromagnetic compatibility (EMC) - Automatic test equipment (ATE) - Part 3: Test procedures

    • The legal and regulatory framework surrounding EN 55025 Vehicle EMC Immunity Testing is primarily governed by the European Unions (EU) electromagnetic compatibility regulations, which are outlined in Directive 2014/30/EU. This directive requires vehicle manufacturers to ensure that their products comply with the relevant EMC standards.

    International and national standards also apply to this specific laboratory test. For example:

  • The International Organization for Standardization (ISO) publishes a series of standards related to electromagnetic compatibility, including ISO 11452-1.

  • The Association for Electrical, Electronics, Information Technology and Telecom Industries in Europe (EICTA) is responsible for promoting the development and application of EMC standards.

    • Standard development organizations play a crucial role in evolving and updating standards. These organizations include:

  • Comité Européen de Normalisation (CEN): The European Committee for Standardization.

  • International Electrotechnical Commission (IEC): A global organization that develops and publishes international electrical and electronic engineering standards.

  • International Organization for Standardization (ISO): A worldwide federation of national standards bodies.

    • Standards evolve through a continuous process of revision, update, and refinement. This ensures that the standards remain relevant and effective in ensuring EMC compliance.

    Specific standard numbers and their scope are outlined below:

  • EMI measuring instruments (e.g., spectrum analyzers)

    • Testing environment requirements include:

  • Temperature: 23C 2C

  • Humidity: 50 10

  • Pressure: 1013 mbar 5

    • Sample preparation procedures involve preparing the vehicle for testing, including:

  • Installing test equipment and software.

  • Configuring the vehicles electrical systems.

    • The testing parameters and conditions include:

  • Frequency range: 30 MHz to 1000 MHz

  • Power level: Up to 500 W

    • Measuring and analyzing the test results involves evaluating the vehicles ability to withstand electromagnetic interference. This includes assessing the magnitude of any electromagnetic fields generated by the vehicle and determining if they comply with regulatory limits.
