Project Overview
This case study describes a collaboration between TPS Elektronik and a system integrator operating in the industrial automation sector.
The project focused on electromagnetic compatibility (EMC) pre-testing to support the client’s preparation for formal EMC compliance testing.
EMC verification is an important step in the development of electronic products intended for industrial environments. Early testing can help identify potential emissions or immunity issues before the final certification process begins.
The Challenge
The client was preparing several automation devices for regulatory compliance and needed to verify their electromagnetic compatibility.
Key requirements included:
- Evaluating conducted and radiated emissions
- Assessing immunity behaviour under typical disturbance scenarios
- Preparing the product design for compliance testing under the European EMC Directive
- Reducing the risk of unexpected issues during formal certification testing
Because the devices were intended for installation in industrial environments, maintaining controlled electromagnetic behaviour was an important design consideration.
EMC Pre-Testing Approach
TPS Elektronik supported the project by performing EMC pre-testing to evaluate the electromagnetic behaviour of the client’s devices before official compliance testing.
The process included:
- Initial product evaluation and review of the device configuration
- Emission measurements under representative operating conditions
- Immunity testing against common disturbance sources
- Documentation of test observations and potential improvement areas
Based on the observations from the pre-testing phase, TPS Elektronik provided technical feedback to support design adjustments where necessary.
This iterative approach can help manufacturers address potential EMC issues earlier in the development process.
Project Outcome
The EMC pre-testing phase enabled the client to identify several areas where design adjustments could improve electromagnetic performance.
After implementing the recommended changes, the client proceeded to formal compliance testing with improved confidence in the device behaviour.
According to the client, the preparation carried out during the pre-testing stage helped streamline the certification process and reduce the likelihood of repeated test cycles.
Following the project, the client continued to collaborate with TPS Elektronik on additional EMC verification tasks for future product developments.
FAQ
-
What is EMC pre-testing?
EMC pre-testing is an early evaluation performed before official compliance testing. It helps identify potential emission or immunity issues during the development phase so that design adjustments can be made before certification testing begins. -
Which regulations are relevant for EMC compliance in Europe?
Electronic equipment placed on the European market typically needs to comply with the European EMC Directive (2014/30/EU). Compliance is generally demonstrated using relevant harmonised standards and testing procedures. -
Does TPS Elektronik provide certification?
TPS Elektronik focuses on engineering support, EMC pre-testing, and measurement services. For formal certification, manufacturers typically work with accredited testing laboratories or certification bodies.
