ANFR: Radiofrequency (RF) radiation devices: SAR display reinforced to better inform the public


Auto translated from French. Source:

The obligation to inform the consumer regarding the specific absorption rate (SAR) is extended, from July 1, 2020, to all radio equipment emitting more than 20 mW and intended to be used near the body. This obligation was previously limited only to mobile telephones. The national agency of frequencies (ANFR) will reinforce the information of the users and will proceed to the control of these devices.

To improve public information and to take account of changes in consumption patterns and the appearance of new devices that may expose consumers to the airwaves, the obligation to display the SAR is extended to all radioelectric equipment whose maximum average power is more than 20 mW and intended to be used near the human body: phones, tablets, certain connected watches, wireless headsets … This obligation will thus allow consumers to choose their equipment in an informed manner. For these devices, the regulations already required measuring the SAR, but the display obligation was previously only applicable to mobile phone devices.

The SAR values ​​must appear in the instructions for use of equipment whose date of first placing on the market is later than July 1 as well as at points of sale, in the immediate vicinity of the equipment concerned. The obligation also applies in the case of free distribution and in all advertising. To ensure consumer protection, the limit value for the “limbs” SAR is set at 4 W / kg. This new value thus supplements the limits already set for the “head” and “trunk” SAR (2 W / Kg). 

As part of its mission to control public exposure to electromagnetic waves, the ANFR will therefore carry out verifications from July 2020 to ensure compliance with these new provisions. The results of the measurements will be available in an open data on the site

Finally, to better understand what DAS is and what will change on July 1, the ANFR has designed videos and infographics for the general public – see
