Certification (CE)

A cost-effective and efficient certification process

Extensive support and advice

Starting from 2013, Cosesy offers extensive support and advice for certification preparation, documentation, pre-compliance testing, failure analysis, on-site debugging, project management, regulations and standards update, etc. for electronics/IoT products with SGS branch in Shenzhen, China. Who is SGS? 

As a result of our knowledge and expertise, we can offer you more than just a regular test house certification service. We enable you to take charge of the product certification process, so that you will gain new insights.

Whether you need assistance for the entire process or guidance for certain parts, we can help you:

° Determine which EU directives and standards apply to your products, and your markets

° Offering you advice and guidance

° Verification of design

° File and document preparation

° EMC (electromagnetic compatibility) testing

° Risk analysis and assessment

° User manual and instruction assessment

° Get a faster response from the lab

° On-site debugging to help understand the failure

° Find an affordable way to validate hardware changes. 


CE mark



We have helped customers

certify over 50 smart products in China, among others:


IEC 62368-1:2018 

RoHS, Reach

FCC (the U.S.), IC (Canada)

Why mark CE with our partner (SGS in China)?


For authority:

SGS is a world’s leading certification and testing company headquartered in Switzerland, with a network of 1250 laboratories in over 100 countries, and over 200 laboratories and 6,000 professionals in China.

For lower cost:

In comparison with the certification cost in Europe, it is undoubtedly cheaper in China, simply because certification process itself demands a lot of time, and the man-power is naturally cheaper in China than in Europe.


What is CE?

CE is a mandatory conformity mark required for a wide variety of products. CE-marking indicates that the product complies with stringent EU product safety directives.

Avoid panic with pre-compliance testing


The secret is to rent SGS laboratories.

Certification requires a large investment in cost and engineering. Before you are sure that you can pass the tests, we recommend you run pre-compliance testing e.g. EMC, RF.

Pre-test is much cheaper than a full certification process, it saves engineers immense amount of time particularly if the full certification happen to fail, and everyone involved is in panic.

Based on a long and strong cooperation with SGS Shenzhen, SGS offers pre-testing service to us, as well as satisfactory support, that means, customer can always rent their lab to test e.g. 

  • RSE - Radiated Spurious Emission
  • CE test - Conducted Emission test
  • RE - Radiated Emission test…
  • 200-point 3D antenna pattern measurement
  • Absolute power and harmonics
  • IP assessment
  • Material test e.g. metal surface treatment and contamination + layer thickness…

The lab can be rented for minimum one hour for around 1000 DKK – 1500 DKK.

There are many advantages with pre-compliance testing, among others: If the pre-compliance testing is passed, it will not be retested for the complete product.

Analyze failure by on-site debugging


When a failure happens during a full certification process, don't panic, our effective actions and solutions will support through the whole process.

The first step is to understand the failure, but often it's difficult to locate the cause.

In this case, Cosesy will arrange a meeting quickly with the customer and SGS lab together to discuss possible causes and improvement suggestions will also be ready.

Cosesy team in China will visit SGS lab, talk to their team so they will prioritize and focus on validating the result of the fresh changes. 


How do you ensure your product continue to comply with CE regulations after updates?

The answer is re-certification.

Re-certification is also easy. Only the updated parts need to be tested, and a complete CE report will be updated. 


Plan certification early in the NPI process.

We suggest:

Plan certification early in the NPI process. Not just to avoid delays and problems in the certification process, but also to avoid large technical changes for example tooling of casings, antenna positions...

Take advantage of our experience and close connection with SGS in Shenzhen, China, we together achieve highly cost-effective and efficient certification process.
