Summary This standard specifies procedures for the evaluation of the peak spatially averaged SAR by repeatable measurements using a simplified model of the head. This standard applies to electromagnetic field (EMF) emitting devices used close to the ear (the transmitting unit of which is close to the head), such as: mobile phones, cordless phones, some types of (head-worn) headphones, etc. When this standard assesses the head peak spatial SAR, a conservative assessment should be given with limited uncertainty for a significant population of people who normally use these devices. The frequency range of this standard is 300 MHz to 6 GHz.
