A comprehensive EMC testing service

Case Study Overview

A major global automotive OEM appointed HORIBA MIRA to handle the entirety of its electromagnetic compatibility (EMC) testing for the UK and Europe.

This partnership enabled the OEM to operate without the significant costs associated with running a large-scale EMC test facility.

Full case study


The test programme was coordinated by HORIBA MIRA engineers embedded within the client’s organisation. As an integrated part of the development team, they have a deep understanding of each project’s specific timeline and requirements. This allowed them to tailor the test plan extremely efficiently.

Likewise, working side-by-side with the OEM engineers ensured that the HORIBA MIRA team was aware of any specific challenges imposed by new parts or new technologies on the vehicle.

This meant that they could identify upcoming test requirements and develop or adapt the test methodologies to support these well in advance.

Test activities typically began with component and systems-level evaluations and progressed through whole-vehicle prototype stages before reaching sign-off. As part of the support, HORIBA MIRA handled all wraparound services, such as vehicle preparation and fault finding, allowing the OEM to take a hands-off approach.

Successes and benefits

HORIBA MIRA handled the entirety of the client’s EMC testing across a broad range of vehicle platforms and powertrain types. Key points included:

  • Integrating into OEM teams to ensure cascade of control to its suppliers, agreeing evaluation plans, monitoring requirements and evaluation criteria.
  • Liaising with suppliers to identify potential EMC issues and flagging any concerns through detailed evaluation of supplier provided reports.
  • Engineers embedded within the client OEM ensures that the vehicle evaluation plan takes into account the latest developments in the programme and responds as efficiently as possible to ensure fast turnaround.
  • Flexible access to HORIBA MIRA’s world-class suite of EMC testing facilities.
  • Full range of wraparound services to ensure that the testing progresses smoothly and efficiently.

The wraparound service that we provide takes a lot of risk out for the manufacturer. If a test vehicle encounters an issue, for instance, our technicians will diagnose, communicate and resolve where possible to ensure project timelines stay on track.
