2. Evaluation method and Limit
According to KDB447498 D01 General RF Exposure Guidance v06 Section 4.3.1 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, listed below, is 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.22 The minimum test separation distance
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 (see 5) of section 4.1). To qualify for SAR test
exclusion, the test separation distances applied must be fully explained and justified by the
operating configurations and exposure conditions of the transmitter and applicable host platform
requirements, typically in the SAR measurement or SAR analysis report, according to the required
published RF exposure KDB procedures. When no other RF exposure testing or reporting is
required, a statement of justification and compliance must be included in the equipment approval, in
lieu of the SAR report, to qualify for the 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 & tablets etc.23 “
[(max. power of channel, including tune-up tolerance, mW)/ (min. test separation distance, mm)] ·
[√f (GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where:
• f (GHz) is the RF channel transmit frequency in GHz
• Power and distance are rounded to the nearest mW and mm before calculation
• The result is rounded to one decimal place for comparison
• 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below
The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm
and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test
separation distance is < 5 mm, a distance of 5 mm according to f) in section 4.1 is applied to
determine SAR test exclusion.
