If I have an FCC certified BLE module, can I use it in a product destined for Europe and CE mark the product with no additional (intentional radiator) testing?
Not likey. The regulations differ a bit. However:
- If you still have the test results, you might be able to compare them to the EU standards and pass the tests
- I heard that a lot of manufacturers just slap on the CE marking and only test for compliance when their compliance is challenged. (At court or somewhere else). When you are confident it will pass, you could do this.
Disclaimer: I only did some research on this matter and have no real life experience whatsoever, so take this with a pinch of salt or mostly some general guidance on which to conduct your own research.
If your module is soldered or connected to a system that you designed, you have to go to an EMC lab and do some tests.
Not all, but just some.
For example, you will have to do the output power test.
This is true in Europe but I guess that holds in the US as well.
When coming to Europe from FCC you need to have a CB Report. It's basically paper.
That paper contains for example the extra tests you need to do to comply to European CE regulations.
UL, TUV and many others do that all the time.
