Your challenge
You need to obtain certification before launching your product?
You need a partner who can help you speed up the measurement and improvement process?
Did you face challenges or failures during EMC testing and need assistance in identifying and resolving the issues?
Our solution to your challenge
Guiding you through the certification process, our assistance includes in-house EMC testing. While not official, this proactive testing helps identify and address potential issues early on, ensuring a smoother path to certification. Leveraging our network with multiple certification bodies, we prioritize a swift and high-quality process.
When customers consider the time it takes to design and develop a product, they are often surprised that it could take anywhere from 2 to 18 months to obtain the certification needed to launch the product in even one country with one certifying body (e.g. FCC certification can take 8-12 weeks, CE certification for medical devices can take 12-16 weeks, best case scenarios). The global market for testing, inspection, and certification (TIC) is projected to surpass a valuation of US$285 billion by the end of 2024 based on different end use applications (Market Research Reports Search Engine (MRRSE) – “Testing, Inspection and Certification (T.I.C.) Market – Global Industry Analysis, Size, Share, Growth, Trends and Forecast 2016 – 2024”).
The complexity of the certification process, particularly in the realm of electromagnetic compatibility testing, can be daunting for customers.
Many “smart” products in today’s market, especially those with wireless connectivity, are subject to certification regulations for radio frequency transmissions and interference at various levels. There isn’t a one-size-fits-all global certification body for these products. Testing must be carried out at accredited labs for each notified body before a product can be legally sold in a specific market. The ramifications of using a product without the appropriate certification are significant, including potential removal from the market and penalties. Our role is to guide customers through this intricate process from the initial design phase up until certification. We understand that successful certification involves more than just paperwork submission and functional product samples; it requires thoughtful engineering design that accounts for certification requirements long before formal testing.
We offer comprehensive support in the following ways:
-
- Pre-Certification Guidance: We assists in selecting the right pre-certified modules or verified designs, streamlining the certification process for existing products, upgrades, and new versions.
- Network with Multiple Certification Bodies: Our well-established network with multiple certification bodies enables collaboration with internationally certified testing houses and labs. This network ensures a smoother and faster measurement and improvement loop.
- EMC Testing Support: Recognizing the importance of EMC testing, we offer assistance in identifying and addressing challenges related to electromagnetic compatibility. While not official testing, our proactive approach helps customers pinpoint and rectify potential issues before formal EMC testing, saving time and resources.
- Pre-compliance testing: Integral to our service, it ensures values stay within the appropriate range under changes in environmental parameters dictated by governing certification bodies, minimizing the need for retesting, delays, and costs.
We help guide customers through this process from design to certification. We can help select the right pre-certified modules or verified design that will expedite certification for existing products, upgrades and new versions.

FAQ
Top FAQ Product Development
We have a product that we would like to push through the notified body (e.g., US FCC Part15, RED directive, Electrical IEC 60950, IEC 61010, IEC 61000, IEC 60601). Can you help us?
Yes we can! We use the following procedure independent of the governing standard:
- We firstly look in the design files of the product (technical file, HW design files, Product description) to get acquainted with the matter.
- We do internal pre-check measurements to detect possible anomalies
- We go to the notified body and perform complete pre-check measurements
- We create patches to fix the anomalies (if possible during the pre-check time)
- We do the official measurements at the notified body.
We have a medical device that needs to pass certification, are you able to help us?
Yes. We can assist with specific EMC problematics (RE, RI, CI, CE) or run your product through complete testing according to IEC 60601. We can assist with the Technical File for EU and US markets as well.
How do you assure that the certification process will be completed on-time and on budget?
- We have internal engineering best practices guidelines regarding how to design and produce products to pass EMC
- We do:
-
- Design checks
- Pre-compliance measurements at our premises
- Pre-compliance measurements at the notified body
Where do electronic products normally fail during the certification process?
We see the biggest challenge in Radiated Emission and Radiated Immunity regarding EMC and poor product and project structure regarding the notified body
What are the biggest issues in EMC?
The most common challenges are related to radiated immunity and radiated emission in the field of 80 MHz to 1 GHz.
Up to 300 MHz mostly due to the operation of switching the power supply,
From 200 MHz to 1 GHz as a result of fast digital signals (clock, communication signals, other fast digital signals…)
Interferences resulting from the ground or earth separation due to safety standards.
Immunity in the proximity field
Very high values of the proximity field reveal EMC vulnerability
Other issues: conductive immunity, conductive emission, ESD (electrostatic discharge)…
Where are the main issues originating from in electronic EMC testing?
- Used mechanical solutions were done with implementation simplicity in mind, forgetting about electrotechnical principles (e.g., how to do terminations, fixation of bigger components, the shape of RF shields)
- Price constraints on the designs, where components related to guarding against EMC phenomena are omitted first – just one too many
- Using other manufacturers’ components or submodules, which are already close to the EMC limits themselves
- Design misconception that the certification of the final design is a sum of all EMC performances of individual components
