Update to Act 3481

Sep 8, 2021 | Brazil

In an effort to update Act 3481 – Technical Requirements and Test Procedures for Conformity Assessment of Charger Used In Mobile Phone, ANATEL, the Brazilian certification body, released Public Consultation No. 47 (Annex).

The main proposed changes are:

  1. Vehicular chargers – ESD testing must be done according to ISO 10605/2008, not IEC 61000-4-2 as before (see item 6.1);
  2. Mint label for vehicular chargers installed inside the car panel will be voluntary (see item 9.1.1). Accordingly, the use of mint labels in this case is optional and eliminates the need of buying mint labels. Additionally, if the manufacturer decides to not use the mint label, they will need to include the ANATEL ID on the charger label (regular marking). An example of devices that can use this exception is a wireless charger installed in the car panel.At this moment, it is not clear if this exception will apply only to vehicular chargers installed behind the car panel (neither seen nor touched by the user) or to the versions where the user can see, and directly touch, its upper surface.
  3. ESD (ISO 10605) and Electrical transient (ISO 7637-2) testing applied exclusively for USB type vehicular chargers installed in the car panel or other parts of the vehicle can be done in a 1st part or 2nd part laboratory (see item 10.4).
  4. Example of device under this scope is USB I/F Box similar to below picture:

This consultation is open for comments until Nov 7th, after which ANATEL will analyze the comments and issue the final document. The publication date of the final version is unknown and will depend on the numbers of contributions. The official document can be accessed using the link below:
