It´s simple. You make an appointment, bring in your device, they test it, it fails, you pay a lot of money. Repeat that 3-5 times,then finally you might succeed.
Or you can buy the norm that is related to this, read it, make the necessary tests by yourself, and then bring it to the test center only when you are sure it is ok.

Slight change! Whether it fails or passes, you pay a lot of money!
