Electromagnetic Compatibility in Road Vehicles

Electromagnetic compatibility in road vehicles is of great importance for the safe, stable and interference-free operation of modern automotive systems. Many critical components used in vehicles, such as electronic control units (ECUs), radars, sensors, communication modules and safety systems, may both emit electromagnetic interference and be affected by surrounding electromagnetic influences. Therefore, EMC testing in vehicles is an essential part of both the design process and the homologation stage.

EMC Tests for Road Vehicles

EMC tests are applied to ensure that electrical and electronic automotive components operate in harmony with other systems. These tests determine that components do not generate electromagnetic interference (emission) and are resistant to environmental disturbances (immunity). In this way, automotive electronics can operate smoothly without compromising driving safety and comfort.

Automotive Testing and Reporting Process

The testing process begins with the technical analysis of the product. After the appropriate test standard and protocol are determined, all tests are carried out in our accredited laboratory in accordance with international standards. Tests are completed under emission and immunity categories. The technical report prepared at the end of the test is submitted to manufacturers to document regulatory compliance and facilitate market entry processes.
