Conformity testing is the cornerstone of any EMC assessment. It ensures that devices, components, and systems meet applicable electromagnetic requirements and do not interfere with other products or environments. This is based on national and international standards that define clear limit values and test procedures. By conducting tests in accordance with these standards, manufacturers create the conditions necessary for market access, approval, and the safe operation of their products. At the same time, these tests help ensure the long-term functionality and reliability of devices in real-world operating environments.
Seibersdorf Laboratories offers a fully accredited testing portfolio that covers all key requirements of the EMC Directive as well as industry-specific product standards.
We help companies make their products secure, legally compliant, and marketable — from prototype to series production — with our extensive testing infrastructure, experienced experts, and clearly structured test processes
Our compliance testing covers all relevant immunity and emission tests for devices and systems operated in a wide variety of electromagnetic environments, such as industrial and commercial settings, as well as for operating conditions with specific requirements.
We check whether devices are causing excessively high levels of electromagnetic interference.
This includes:
Testing the robustness of the device against external interference.
This includes:
Electrical and electronic systems are now the backbone of modern vehicles. They control safety-critical functions, support comfort systems, connect vehicles with their environment and form the basis for e-mobility. We support manufacturers and suppliers in carrying out standard-compliant emission and immunity tests of automotive components in one of our anechoic chambers as well as automotive pulse tests in accordance with ISO and OEM standards and requirements on our transient test benches/electrical system simulators.
Since 2025, our EMC test center has had a state-of-the-art reverberation chamber that meets the requirements of international standards ISO 11452-11 and IEC 61000-4-21 for testing electromagnetic compatibility (EMC). This test procedure allows us to evaluate the immunity of electronic devices even at very high field strengths.
Unlike traditional anechoic chambers, the reverberation chamber uses statistical field distributions to expose products to uniform electromagnetic exposure. This allows tests to be conducted with exceptional efficiency and precision—even for large test specimens or complex applications that can be accommodated within the test volume.
With this new testing method, we are expanding our service portfolio. Our customers will benefit from reliable results for industry-specific standards in the automotive and defense sectors.
We perform EMC tests on rolling stock and rail infrastructure to ensure that rail vehicles, signaling technology, energy supply systems, and other electrical components function reliably in the complex electromagnetic environment of rail operations while avoiding undue disruptions.
We conduct testing in accordance with the relevant European product standards and also take into account specific requirements from train manufacturers, infrastructure operators, and transport companies that must be met as part of certification and acceptance procedures.
Our tests are based on the relevant standards and technical requirements of the railway industry, including:
With accredited measurements of emissions and immunity, analysis of electromagnetic interactions, and our technical expertise, we support manufacturers, system integrators, and operators in the development, certification, and operation of modern railway systems.
Railway systems operate in an environment with high electromagnetic interference: high currents, strong magnetic fields, long conduction paths. We test in accordance with EN 50121-x and related railway standards and simulate typical operating conditions.
Our portfolio of testing standards includes:
Electronic devices on rail vehicles are exposed to extreme conditions. As an accredited test laboratory, we ensure that your components meet the strict requirements of EN 50155. We validate the electrical safety and functionality of your systems so that they can survive tough rail operations in the long term.
To confirm the compliance of your products, we carry out the decisive electrical type tests:
Special tests require precision, flexibility and a deep understanding of the respective areas of application. Our laboratory offer modern testing environments, experienced EMC specialists and the reliability of accredited testing processes.
We provide you with reliable results, clear recommendations for action and are a partner who understands critical applications from a technical and regulatory perspective.
We carry out tests and measurements for technical systems that are used in particularly demanding application environments. In doing so, we help manufacturers and operators ensure the electromagnetic compatibility and reliability of their systems under realistic operating conditions.
We start where standards are no longer sufficient.
In certain industries, there are significantly stricter EMC requirements than in traditional industry. Aerospace, defense systems, or specialized high-performance devices must withstand extreme electromagnetic conditions without interfering with each other or being disturbed. This is exactly where the special tests at Seibersdorf Laboratories come in: We test where complex operating conditions, safety-critical applications or industry-specific special standards are paramount.
Special tests require precision, flexibility and a deep understanding of the respective areas of application. Our laboratories offer modern testing environments, experienced EMC specialists and the safety of accredited testing processes.
For companies, this means reliable results, predictable approval processes and the assurance that products function stably even under exceptional conditions.
Devices and systems in aviation or military environments are frequently exposed to strong electromagnetic fields, changing loads, long lines or extreme operating conditions. Mistakes here would not only be costly, but could also jeopardize security. For this reason, these industries require an EMC assessment that goes well beyond traditional standards.
You get clarity about the actual usability of your product before it is integrated into a highly critical environment.
We cover the most important standard areas that fall outside of classic EMC tests. The services are modular and can be combined for devices or systems in several areas of application.
Our portfolio of testing standards includes:
For decision makers, these tests not only offer technical safety, but also clear economic benefits:
They reduce development time, ensure product quality and strengthen the market position against competitors.
For buildings, industrial plants as well as large machines and complex technical systems, we offer EMC tests directly on site to investigate electromagnetic disturbances under real operating conditions. Such investigations are particularly necessary when systems cannot be tested in a classic testing environment due to their size, integration into existing infrastructure or operating conditions.
Electromagnetic challenges occur not only in the laboratory — but especially in real world operating conditions.
In production facilites, office buildings, technical centers, or critical infrastructure environments, a wide variety of electromagnetic sources coexist: machines, frequency inverters, control panels, wireless applications, power supplies, and IT systems. If these are not properly coordinated, interference can occur—resulting in outages, data errors, unintended shutdowns, or sporadic malfunctions.
This is precicely where Seibersdorf Laboratories' EMC testing comes into play: We conduct on-site analyses of buildings, facilities and technical areas, identify sources of malefunction and lay the groundwork for reliable and safe operations.
This provides significant added value for your business: improving operational reliability and avoiding costly downtime.
Companies tend to call EMC experts only when a problem has already occurred. However, our experience shows that a preventive assessment of buildings, systems or new technical areas prevents many problems from the outset. An early EMC analysis provides clear planning security, particularly for new buildings, modifications or the replacement of large machines.
Early EMC tests mean: less operating risk, reliable processes and lower follow-up costs for expansions or modernizations.
Seibersdorf combines scientific precision with practical experience directly from industry.
Companies benefit from:
A well-designed housing can significantly reduce unwanted emissions while increasing a device's resistance to electromagnetic interference. The choice of material, housing design, contacts, seals, and cable openings all have a significant influence on the shielding effect.
The housing of an electronic device is decisive for the EMC properties of the finished product. A well-designed housing reduces emissions and increases immunity and is therefore crucial for passing EMC tests.
Inspection of Entire Housings
All tests on the housing parts can also be carried out on the entire housing, in which a standard-compliant emission measurement is carried out in the anechoic chamber. To do this, an emission source is placed inside the housing, which generates a broadband signal. The shielding effect of the housing is determined by measuring the emission.
The dielectric material parameters are essential parameters for the characterization of materials when their behavior in electromagnetic fields (spatial propagation, damping) is to be described. We offer two different measurement methods:
The dielectric material parameters determined by measurement can be used in various numerical simulations.
Numerical simulation offers cost-effective support with continuous optimization for the entire development cycle from the first prototypes to the finished product. In numerical simulation, field quantities can be made available that are not accessible through measurement. In addition, any number of changes to products can be carried out in the simulation, which in reality would require a great deal of effort.
We offer the following numerical methods:
We are happy to model your scenario with the appropriate simulation software and can help optimize your product by making the electromagnetic fields visible.
The step from CAD model in simulation, to illustrative 3D printing (e.g. using cutting-edge laser sintering, SLS) to EMC evaluation for functional prototypes, or even for the first small series, is also a smaller one.
We also have many years of expertise in the area of 3D printing. Our competent team will be happy to advise you and support your development from initial planning to implementation of the finished product.
EMC project support is a key success factor for the development and certification of modern devices and systems. Early and continuous support can reduce risks, shorten development times and avoid cost-intensive rework. We provide comprehensive support — from selecting relevant standards and conducting pre-compliance testing to implementing targeted interference suppression measures.
Is your product compatible with other devices and compliant with the legal EMC requirements of the European market?
Before launching their product on the market, manufacturers must demonstrate compliance with the relevant regulations. These vary depending on the economic region. For the EMC sector, for example, these include the EMC Directive and UN ECE Regulation 10 in Europe, FCC CFR 47 in the United States, and MIL standards for aerospace and military technology.
Often, it is not enough to simply meet the legal requirements. However, tenders may contain specific EMC requirements that go beyond the minimum legal requirements and demand special test conditions.
We support you in designing EMC-compliant devices and systems from the initial concept through to acceptance testing. We assist you in selecting the appropriate EMC regulations and standards for the relevant domestic and international markets and in interpreting and implementing EMC requirements in tenders and contracts.
We perform pre-compliance measurements and support you in EMC-compliant device and system design, EMC system planning, and the resolution of EMC issues. To this end, we have access to all the testing methods of a modern EMC test center.
Knowledge and experience are key components for effectively managing electromagnetic compatibility. Through our events, seminars, and workshops, we offer practical training and share our expertise with professionals in industry and technology. In doing so, we combine in-depth technical knowledge with real-world applications from everyday work.
Once a year, in technical cooperation with TU Graz, the OVE and the IEEE EMC Austria Chapter, we organize the Austrian EMC Conference, which takes place alternately at the Seibersdorf site and at TU Graz.
As speakers, we are happy to share our experience with you. At our Academy, we offer a 6-day EMC seminar series with a modular structure, allowing each module to be booked individually.
Training courses tailored specifically to your needs are also possible. These can be held in our seminar rooms, but also as an in-house seminar at your premises.
