This week (April 17th), ANATEL published Act 5155, replacing the current Act 5159. Effective October 14th, 2024, this new regulation introduces updated testing requirements for mobile phone chargers.
Revised Testing Parameters
Under Act 5155, testing requirements for mobile phone chargers have been enhanced to ensure safety and reliability. This includes rigorous testing, including 1,000 cycles of connection and disconnection, withstand voltage testing (2000V) to check leakage current, and various mechanical tests to ensure chargers withstand stress safely.
Electrostatic Discharge (ESD) and Surge Testing
Under the provisions of Act 5155, Electrostatic Discharge (ESD) requirements for Vehicular Chargers have been revised. Specifically, ESD must now adhere to Item 8.3 of ISO 10605/2008, with levels established at 6 kV for contact discharges and 8 kV for air discharges, thereby modifying the previous 2/4kV and 4/6kV requirements.
Dimensional and Mechanical Testing
Starting January 1st, 2025, adapters must comply with dimensional specifications outlined in standard ABNT NBR NM 60884-1/2010 and Annex A of standard ABNT NBR 14136/2012. Additionally, rigorous mechanical, electrical, and thermal stresses testing are required to assess charger durability.
Enhanced Safety Protocols and Transition Guidelines
Effective October 14th, all renewals of wall adapters used for mobile phones must comply with Act 5155 and undergo new safety testing. However, vehicle chargers produced under Act 5159 are exempt from repeat testing during renewal. The new regulation mandates safety testing on a sample size of 22 adapters to ensure robust assessment procedures.
