On April 17th) ANATEL published the new Act 5155 with testing requirements for Mobile phone’s Chargers.
This new act will come into force on October 14th, 2024, replacing the actual Act 5159.
Here are the main changes with the new Act 5155:
Electrostatic Discharge (ESD) Levels for Vehicular Chargers: Under the new Act, the ESD requirements for Vehicular Chargers have been refined. Specifically, ESD must now comply with Item 8.3 of ISO 10605/2008, with levels set at 6 kV (removed 2/4kV) for contact discharges and 8 kV (removed 4/6kV) for air discharges.
Streamlined Surge and Transient Immunity Testing: For Vehicular Chargers, Surge and transient immunity testing now only need to be applied in pulses 2a, 3a, and 3b, as per ISO 7637-2/2004, eliminating the requirement for pulses 2b.
Safety Tests on Wall Adapters: The new regulations stipulate that 22 normal samples of the adapter will be required for safety testing, ensuring robust assessment procedures.
Dimensional test for wall adapters’ Plug: Effective from January 1st, 2025, adapters will be mandatory to demonstrate compliance with the dimension specifications, as per item 9.1 of standard ABNT NBR NM 60884-1/2010 (Plugs and sockets for domestic and similar use) and Annex A of standard ABNT NBR 14136/2012 (Plugs and sockets for domestic and similar use up to 20A/250 V in AC current). If manufacturer wishes to already testing using Act 5155, this dimensional requirement will be optional for chargers homologated before Jan 1st, 2025.
New mechanical, electrical and thermal stresses testing for wall adaptor: 1,000 cycles of connection and disconnection to see if there is any deterioration that affects safety or prevents their subsequent use, withstand voltage (2000V) after the connection/disconnection cycle to check leakage current. Chargers must withstand mechanical testing such as Free Fall, Impact, Compression, Traction, and Abrasion tests without exhibiting safety-compromising deterioration.
As for Oct 14th, all renewal of wall adapters used for mobile phones, it will be necessary to update the CoC to the new Act 5155 doing the new safety testing. Vehicles chargers done according to Act 5159 will not need to repeat testing during the renewal.
