SAR Testing

Specific Absorption Rate (SAR) is the unit of measurement for the amount of radio frequency (RF) absorbed by the body when using a wireless device. SAR testing measures the electromagnetic energy absorbed by a body using a wireless device. SAR testing is intended to verify that a device does not exceed a country’s established RF exposure limits. The SAR value is expressed in terms of watts per kilogram (W/kg) or milliwatts per gram (mW/g). Government agencies around the world are increasingly focused on the health and safety impact of products using RF transmitters. Manufacturers of wireless devices are required to demonstrate their products' compliance with the RF exposure limits set forth in national specific absorption rate (SAR) regulations. The most generally accepted method for measuring SAR values is the direct method SAR test. CDG provides SAR Testing on portable and mobile telecommunications equipment. Your product will be tested with state-of-the-art equipment, using cutting edge technology, providing you with accurate and dependable RF exposure measurements.

Parameters that can affect SAR include:

  • Types of radio service (cellular, PCS, LMR, WLAN, etc.)
  • Types of modulations (CDMA, GMSK, TDMA, AMPS, etc.)
  • Physical orientation to person (held-to-ear, held-to-face, belt-clip, lap-held, etc.)
  • RF power level (in Watts or mW)
  • Changes to transmitter, antenna (extracted/retracted) or accessories (clips, batteries, etc.)

We Conduct SAR Test for Following Standards:

IEEE STD 1528 IEEE, FCC OET 65, IC RSS-102, EN 50361, EN 62311, IEC 62209-1, EN 62209-2, ACMA, ARIB STD-56, EN 50360, EN 50364, EN 50371, EN 50385
