IEC/IEEE 62209-1528 Standard
New IEC/IEEE 62209-1528 standard combines three already existing standards, IEC 62209-1:2016, IEC 62209-2:2010, and IEEE Std 1528-2013. The new standard includes many significant technical changes considering SAR testing, compared to the existing ones. The changes are related to, for example, testing of devices with proximity sensors, uncertainty analysis, application specific phantoms and device holder specifications.
One of the most significant changes is that this new standard has broadened the SAR testing frequency range. The widest testing frequency range among the united standards has so far been from 30 MHz to 6 GHz, whereas the new standard includes testing frequencies down to 4 MHz and up to 10 GHz. The new wide frequency range covers ISM frequencies of 13.553-13.567 MHz.
Verkotan has the capability to test 13.553-13.567 MHz frequencies
Many common RFID (radio frequency identification) and NFC (Near Field Communication) systems use this 13.553-13.567 MHz ISM band. Normal life devices such as credit cards, wireless chargers, wireless payment systems and personnel identification, use these frequencies.
According to the new IEC/IEEE 62209-1528 standard, SAR testing is now required for devices that operate on output power higher than 20mW and operate at 13.56 MHz frequency. Verkotan is one of the few laboratories that has the capability to do the SAR testing at that specific frequency area. Testing SAR at 13.56 MHz requires specific blend of tissue simulating liquid. Verkotan has the capability to blend the required specific tissue simulating liquid for SAR testing at the frequency of 13.56 MHz. In addition, Verkotan can also offer these specific tissue simulating liquids, for example, for the purpose of R&D phase testing.
Applicability of the new standard
The standard has been announced to be mandatory in Canada by ISED (Innovation, Science and Economic Development Canada) since third of May 2021. This means that devices, which are operating at a frequency range from 4 MHz to 6 GHz, will be required to have a certification of a conducted SAR test or alternatively an SAR exemption report. For devices that use frequency above 6 GHz, the power density is sufficient metric for assessing RF exposure compliance. Read more about the subject from notice 2020-DRS0020.
