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.
