IEC 62209-3 Fast SAR Automatic Measurement System,CSAR3D - SAR
System With Novel Vector Array Technology
SAR: the full English name of SAR is specific absorption rate,
which is generally called electromagnetic wave absorption ratio or
specific absorption rate in Chinese. It is the electromagnetic wave
energy absorption ratio of mobile phone or wireless product, which
is defined as: under the action of external electromagnetic field,
induced electromagnetic field will be generated in human body.
Since various organs of the human body are lossy media, the
electromagnetic field in the body will produce current, resulting
in the absorption and dissipation of electromagnetic energy.
Specific absorption rate (SAR) test is a radio frequency (RF)
dosimetry method to quantify the size and distribution of
electromagnetic energy absorbed by biological objects exposed to RF
field. Excessive exposure to RF energy will damage human tissues.
In order to prevent this from happening, many countries in the
world have introduced standards to limit the amount of RF radiation
allowed by all types of transmitters. SAR is often used to
characterize this physical process in biological dosimetry. The
meaning of SAR is the electromagnetic power absorbed or consumed by
human tissue per unit mass, in w / kg.

Standard: YD / t1644
Limit requirements: the SAR limit takes 10g average value, and the
limit is 2.0w/kg.
CE test standard:
Test specification: EN62209-1:2016

limit is 2.0w/kg.
FCC test standard:
The standards are: 47cfr part 2.1093, FCC OET bulletin 65 supply C,
ANSI / IEEE C95.1 and c95.3, ANSI / IEEE P1528
Limit requirements: the SAR limit takes 1g as the unit to calculate
the peak, and the limit is 1.6w/kg
