Last week, on April 17th, Brazil ANATEL published the new Act 5155, which outlines testing requirements for mobile phone chargers. This new act is set to take effect on October 14th, 2024, replacing the current Act 5159.
Here are the main changes introduced by the new Act 5155:
Electrostatic Discharge (ESD) Levels for Vehicular Chargers: The ESD requirements for Vehicular Chargers have been refined under the new Act. Specifically, ESD must now comply with Item 8.3 of ISO 10605/2008, with levels set at 6 kV for contact discharges and 8 kV for air discharges, removing the previous 2/4kV and 4/6kV levels respectively.
Streamlined Surge and Transient Immunity Testing: Surge and transient immunity testing for Vehicular Chargers 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: Starting from January 1st, 2025, adapters must demonstrate compliance with the dimension specifications outlined in item 9.1 of standard ABNT NBR NM 60884-1/2010 and Annex A of standard ABNT NBR 14136/2012. If manufacturers wish to test using Act 5155 before this date, this dimensional requirement will be optional for chargers homologated before January 1st, 2025.
New Mechanical, Electrical, and Thermal Stresses Testing for Wall Adaptors: Chargers must undergo 1,000 cycles of connection and disconnection to check for deterioration affecting safety or subsequent use. They must also withstand a withstand voltage (2000V) test after the connection/disconnection cycle to check for leakage current. Mechanical testing such as Free Fall, Impact, Compression, Traction, and Abrasion tests must be conducted to ensure chargers do not exhibit safety-compromising deterioration.
Effective October 14th, all renewals of wall adapters used for mobile phones will require an update to comply with the new Act 5155 and undergo the new safety testing. Vehicle chargers certified under Act 5159 will not need to repeat testing during renewal.
