The National Radio Frequency Agency (ANFR) carry out annual measurements of SAR control (Specific absorption rate) of smartphones to check their relevance and compliance with the maximum thresholds.
In 2020, she announced that she had tested 95 smartphones obtained through traditional sales channels and which therefore correspond to models sold to consumers, and not copies loaned by manufacturers which may have been modified to meet expectations.
The ANFR carried out three types of measurement: head SAR, trunk SAR and limb SAR, the first two not to exceed 2 W / Kg and the last 4 W / Kg. No exceedance was observed concerning the head SAR and limb SAR measurements on the different models tested.
For trunk SAR, 9 smartphones (see table) were pinned for values exceeding the famous 2 W / Kg. Overall, 8 of them were the subject of a corrective update which allowed them to return to values below the maximum threshold and were therefore able to remain marketed.
A model, the Razer Phone 2, for its part was withdrawn from the market “after voluntary recall from the holders of this terminal. Due to a trunk SAR of 3.29 W / Kg, the ANFR had given notice in early 2020 to the company Razer to take the necessary measures.The latter had opted for a withdrawal from the market with a recall procedure for telephones already sold.
