What is BS EN 62209-1- Procedure for determining the specific absorption rate of human exposure to radio frequency fields about?
BS EN 62209-1 is a safety standard on the devices used next to the ear (Frequency range of 300 MHz to 6 GHz).
BS EN 62209-1 specifies protocols and test procedures for the measurement of the peak spatial-average SAR induced inside a simplified model of the head with defined reproducibility.
BS EN 62209-1 applies to certain electromagnetic field (EMF) transmitting devices that are positioned next to the ear, where the radiating structures of the device are near the human head, such as mobile phones, cordless phones, certain headsets, etc. These protocols and test procedures provide a conservative estimate with limited uncertainty for the peak-spatial SAR that would occur in the head for a significant majority of people during normal use of these devices.
Note: The applicable frequency range is from 300 MHz to 6 GHz.
Who is BS EN 62209-1- Procedure for determining the specific absorption rate of human exposure to radio frequency fields for?
BS EN 62209-1 on devices used next to the ear (Frequency range of 300 MHz to 6 GHz is relevant to:
- Manufacturers of wireless communication devices such as mobile phones, cordless phones, certain headsets
- Manufacturers of electromagnetic field (EMF) transmitting devices that are positioned next to the ear
- SAR and EMC testing authorities
Why should you use BS EN 62209-1- Procedure for determining the specific absorption rate of human exposure to radio frequency fields?
IEC TC 106 has the scope to prepare International Standards on measurement and calculation methods used to assess human exposure to electric, magnetic, and electromagnetic fields. IEC TC 106 has developed BS EN 62209-1 to provide procedures to evaluate the specific absorption rate (SAR) of human exposures due to electromagnetic field (EMF) transmitting devices when held close to the ear.
The types of devices include but are not limited to mobile telephones, cordless telephones, headphones, etc., which are used close to the ear. While basic restrictions on SAR in the ICNIRP Guidelines [64] 1 go up to 10 GHz, the frequency range for BS EN 62209-1 is limited to an upper-end frequency of 6 GHz since current wireless handsets operate below this frequency. IEC TC 106 and IEEE/ICES TC342 worked together formally through common membership to achieve the goal of harmonization, between IEC TC 106 Maintenance Team 1 for BS EN 62209-1 and IEEE/ICES TC34 for IEEE Std 1528 [66]. During the process, a primary effort involved was to harmonize these two standards. To aid the user of BS EN 62209-1, a quick start guide has been prepared and included as an informative annex. A SAR measurement system consists of the SAM phantom (a human head model) filled with tissue-equivalent liquid, electronic measurement instrumentation, a scanning system, and a DUT holder. BS EN 62209-1 provides test procedures for a sagittally-bisected SAM phantom oriented horizontally only. For the typical set-up of a sagittally-bisected phantom, each half of the head model is placed on its side, and the DUT is placed underneath.
Overall, BS EN 62209-1 is useful as it guides on the maximum deviation of the SAR measured when rotating around the major axis of the probe while it is exposed to a wave impinging from a direction along its major axis. BS EN 62209-1 assist with the transmitting frequency range associated with a specific wireless operating mode.
