The Agência Nacional de Telecomunicações (ANATEL) in Brazil updated the test procedures for evaluating the Specific Absorption Rate (SAR) of telecommunications products.

ANATEL published Act 1630 on March 11th, 2021. The new Act revokes Act No. 955, dated February 8th, 2018.

The major changes are:

• ANATEL now requires SAR tests for portable devices operating from 4MHz to 6GHz (previously SAR tests would apply to portable devices operating from 300MHz to 6GHz). Low power devices (average power below 20mW and peak power below 20W) that are portable continue to be exempt from SAR tests regardless of the operating frequency band
• Alignment of the testing procedures with the IEC/IEEE 62209-1528 standard, for certification and homologation purposes of portable terminal stations, in the 4MHz to 6GHz radio frequency band
• Inclusion of Time-Averaging SAR (TAS) evaluation procedures
• Approving the considerations in the evaluation of products with proximity sensors, as provided in item 7.7 of the IEC/IEEE 62209-1528 standard, after 180 (one hundred and eighty) days from the publication of the Act
• To determine test procedures for Dynamic Power Control and Exposure Time-Averaging (DPC-ETA) in the verification of TAS protocol, on a provisional basis, until the final version of the technical standard of the working group JGW-13 of Technical Committee 106 of the International Electrotechnical Commission (IEC) is published
