Scope

This Standard defines the procedure to determine the specific absorption rate (SAR) for
hand-held devices used in close proximity to the ear.
It applies to any electromagnetic field (EMF) transmitting device intended to be used
with the radiating part of the device in close proximity to the human head and held against the
ear, including mobile phones, cordless phones, etc. The frequency range is 300 MHz to 3
GHz.
The objective of this Standard is to specify the measurement method for demonstration
of compliance with the specific absorption rate (SAR) limits for such devices. The standard
is about the measurement method, rather than the safety thresholds.

Summary	This standard specifies the use of emission portion close to the ear using a handheld wireless communication device specific absorption rate assessment procedures. This standard applies to the operating frequency range of 300MHz-3GHz arbitrary electromagnetic field emission devices, such as: mobile phones, cordless phones and so on. The purpose of this section is to demonstrate how safety limits according to the corresponding measuring device under test SAR value, this part is just a method of electromagnetic radiation measurement standards, rather than on a standard safety limits.
