The full English name of SAR is Specific Absorption Rate, commonly known as electromagnetic wave absorption ratio or specific absorption rate, which is the electromagnetic wave energy absorption ratio of mobile phones or wireless products. The detailed definition: Under the action of the external electromagnetic field, the human body will generate an induced electromagnetic field. Since various organs of the human body are lossy media, the electromagnetic field in the body will generate electric currents, leading to absorption and dissipation of electromagnetic energy. SAR is commonly used to express this physical process in biological dosimetry.
SAR refers to the electromagnetic power absorbed or consumed by a unit mass of human tissue, and the unit is W/kg.

However, our SAR services do not only refer to European standards. We can also perform other internationally recognized SAR measurements. The following guidelines are fundamental to this:
USA
IEEE C 95.1-1992/IEEE C 95.1-1999 / IEEE C 95.1-2005
IEEE C 95.3-2002
IEEE 1528-2013 (KDB Publication 447498 and KDB Publication 865664)
Canada
RSS-102 2015-03
Australia
Radio communications (Electromagnetic Radiation — Human Exposure) Standard 2014
Korea
The SAR standard of Korea is close to that of America FCC.
Japan
ARIB STD-T56
Limit requirement: Japan’s SAR limit is the same as Europe’s 2.0W/Kg (10g average) standard.
Note: Non-mandatory standard.
We support SAR testing on mobile devices such as mobile phones, tablets, and walkie-talkies. Test frequency ranges from 300MHz to 6GHz, including 2G, 3G, 4G, WIFI and other communication systems.
