The recommendation includes the evaluation of the most common types of EMF devices or applications (including static fields) in humans for non-medical purposes. The main evaluation criteria are the biological effect thresholds achieved in the applications, i.e. those field strengths or SAR values in the tissue above which biological effects can be detected. The thresholds above which a health risk cannot be excluded are also important. In addition, this recommendation specifies the technical requirements for the personnel who use the equipment on humans.
