▍What is ANATEL Homologation?

ANATEL is a short for Agencia Nacional de Telecomunicacoes which is Brazil governmental authority to certified communication products for both compulsory and voluntary certification. Its approval and compliance procedures are the same both for Brazil domestic and abroad products. If products are applicable to compulsory certification, the testing result and report must be in line with the specified rules and regulations as requested by ANATEL. Product certificate shall be granted by ANATEL first before product is circulated in marketing and put into practical application.

▍Who is liable for ANATEL Homologation? 

The Brazil governmental standard organizations, other recognized certification bodies and testing labs are ANATEL certification authority for analyzing the production system of manufacturing unit, such as product design process, procurement, manufacturing process, after service and so on to verify the physical product to be complied with Brazil standard.

The new standard KC 62133-2:2020 has been implemented. The differences between KC62133-2
and IEC62133-2 are briefly summarized as follows：Definitions from KS C IEC61960-3 application scope (for mobile devices)- Coin-shaped cells and batteries using them are excluded from the scope of
application- Personal transporter under 25 km / hr(Self balancing scooter, E-bike)
1) Coin-shaped cells and batteries will be excluded from the scope- it cannot be expanded, because of the old KC scope (there is no justification)
2) Self balancing scooter etc. will be in the scope- This product is one of dangerous good, but the scope of IEC standard cannot be covered. So KC 62133-2 : 2020 will include it in the scope before new IEC standard
develops.
