Specific Absorption Rate
Specific absorption rate (SAR) Summary
SAR standards
The SAR standards of SAR-related international organizations and major countries
| Classification | Korea | Japan | U.S. | CENELEC1) | ICNIRP2) | IEEE3) | |
|---|---|---|---|---|---|---|---|
| Frequency range (Hz) | 105) ~ 1010) | 105) ~ 3X108) | 105) ~ X108) | 106) ~ X1011) | 105) ~ 1010) | 105) ~ X106) | |
| Normal use (W/kg) |
Whole body | 0.08 | 0.08 | 0.08 | 0.08 | 0.08 | 0.08 |
| Head/trunk | 1.6 | 2 | 1.6 | 2 | 2 | 2 | |
| Limbs | 4 | 4 | 4 | 4 | 4 | 4 | |
| Occupational user (W/kg) |
Whole body | 0.4 | 0.4 | 0.4 | 0.4 | 0.4 | 0.4 |
| Head/trunk | 8 | 10 | 8 | 10 | 10 | 10 | |
| Limbs | 20 | 20 | 20 | 20 | 20 | 20 | |
- Note) Head/trunk refers to body parts excluding the limbs; the SAR standard for this part is the average maximum value for 1 gram of arbitrary human tissue in Korea and the U.S. while the SAR standard of Japan, CENELEC, ICNIRP, IEEE and limbs is based on the average maximum value for 10 grams of arbitrary human tissue.
