Mexico IFT changes SAR requirements for in-country testing

Mexico Instituto Federal de Telecomunicaciones (IFT) published IFT-012-2019 which defines technical specifications for compliance on the maximum limits of Specific Absorption Rate (SAR) for in-country testing.


IFT-012-2019 mandates SAR in-country testing requirements for mobile terminal equipment and will be mandatory on 26th February 2021, a year after the publication date.


IFT-012-2019 is in line with the following international standards:


1. IEC 62209-1: Measurement procedure for the assessment of specific absorption rate of human exposure to radiofrequency fields from hand-held and body-mounted wireless communication devices- Part 1: Devices used next to the ear (frequency range of 300 MHz to 6 GHz).


2. IEC 62209-2: Human exposure to radiofrequency fields from hand-held and body-mounted wireless communication devices-Human models, instrumentation, and procedures - Part. 2: Procedure to determine the specific absorption ratio (SAR) for wireless communication devices used in close proximity to the human body (frequency range of 30 MHz to 6 GHz).


3. International Commission on Non-Ionizing Radiation Protection, "Guidelines for limiting

exposure to time-varying electric, magnetic and electromagnetic fields (up to 300 GHz)".

IFT-012-2019 will apply to telecommunications devices which may be connected to a

telecommunications network and/or make use of the radio spectrum in the frequency range of 30 MHz to 6 GHz and that are used:


  • a. Near the head, particularly near the ear, in the 300 MHz - 6 GHz frequency range, and / or

  • b. At a distance less than or equal to 200 mm from the human body, in the 300 MHz - 6 GHz frequency range
