General SAR test exclusion guidance 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(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.29 a) For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [ (푚푎푥.푝표푤푒푟 표푓 푐ℎ푎푛푛푒푙,푖푛푐푙푢푑푖푛푔 푡푢푛푒−푢푝 푡표푙푒푟푎푛푐푒,푚푊) (푚푖푛.푡푒푠푡 푠푒푝푎푟푎푡푖표푛 푑푖푠푡푎푛푐푒,푚푚) ] × √f (GHz) ≤ 3.0 for 1g SAR [ (푚푎푥.푝표푤푒푟 표푓 푐ℎ푎푛푛푒푙,푖푛푐푙푢푑푖푛푔 푡푢푛푒−푢푝 푡표푙푒푟푎푛푐푒,푚푊) (푚푖푛.푡푒푠푡 푠푒푝푎푟푎푡푖표푛 푑푖푠푡푎푛푐푒,푚푚) ] × √f (GHz) ≤ 7.5 for 10g 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 calculation31  The result is rounded to one decimal place for comparison  The values 3.0 and 7.5 are referred to as numeric thresholds in step b) below The test exclusions are applicable only when the minimum test separation distance …
