General SAR test exclusion guidance
Standalone SAR test exclusion considerations
● Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head
or body and 10-g extremity SAR evaluation for general population exposure conditions, by
measurement or numerical simulation, is not required when the corresponding SAR Test
Exclusion Threshold condition(s), listed below, is (are) satisfied. These test exclusion conditions
are based on source-based time-averaged maximum conducted output power of the RF channel
requiring evaluation, adjusted for tune-up tolerance, and the minimum test separation distance
required for the exposure conditions.28 The minimum test separation distance defined in 4.1 f) is
determined by the smallest distance from the antenna and radiating structures or outer surface of
the device, according to the host form factor, exposure conditions and platform requirements, to
any part of the body or extremity of a user or bystander. To qualify for SAR test exclusion, the test
separation distances applied must be fully explained and justified, typically in the SAR
measurement or SAR analysis report, by the operating configurations and exposure conditions of
the transmitter and applicable host platform requirements, according to the required published RF
exposure KDB procedures. When no other RF exposure testing or reporting are required, a
statement of justification and compliance must be included in the equipment approval, in lieu of
the SAR report, to qualify for SAR test exclusion. When required, the device specific conditions
described in the other published RF exposure KDB procedures must be satisfied before applying
these SAR test exclusion provisions; for example, handheld PTT two-way radios, handsets,
laptops and tablets, etc.
