What is SAR?
Specific Absorption Rate (SAR) is a measure of the amount of RF power deposited in the human head or body whenever a mobile phone or other wireless radio device transmits. It is the maximum SAR value (in units of Watts/kilogram) that is measured during SAR compliance testing
All our mobile phone models are tested to make sure they meet national and international exposure limits for exposure to radiofrequency emissions, before they can be sold in each market.
The SAR values reported for each model of mobile phone tend to significantly overstate real-life exposure levels, as models of phones are tested at maximum power levels under laboratory conditions to ensure that they comply.
Mobile phones tend not to operate at maximum power levels during everyday use. In order to avoid network interference, improve battery life and available call time, mobile phones constantly adapt to the minimum power required to make and maintain a call.
How are mobile phones tested?
Each model of mobile phone is tested using both a 'phantom' head and a separate 'phantom' torso for body-worn measurements. he phantoms are filled with liquids that simulate human tissue and SAR values are measured with the phone at maximum power while operating at its different frequencies and placed in a number of normal use positions.
The test procedures measure each model of phone in a range of positions when held to the ear to make a phone call. Phones are also tested in body-worn configurations using belt-clips, holsters or similar accessories if they are provided or at a slight distance from the phantom to simulate clothing or the intended use of the phone.
A probe inside the liquid measures the electric field strength inside the phantom and shows the maximum SAR value for the model of mobile phone.
It is a complex procedure which including the testing of phone accessories can take up to two weeks.
What is standard of SAR in India:
At present, India follows an SAR limit of 2 watts/kg in accordance with International Commission on Non-Ionising Radiation Protection Association (ICNIRP) norms.

But with effect from 1st of September, 2012 all mobile phones sold in India should comply with guidelines & suggestions provided by Inter-Ministerial Committee on EMF Radiation set up by Ministry of Communications and Information Technology, Government of India. The product has to tested for SAR absorption as per FCC norms of United States of America by FCC approved testing laboratory or Telecom Engineering Centre, India and has to comply w with the maximum SAR limits of 1.6 W/kg. average over a six minute period and taken over a volume containing a mass of 1 gram of human tissue. According to these latest norms, the handsets will now have to display the SAR level. 

SAR information for models tested in compliance with Guidelines and suggestions of Department of Telecommunications, Government of India is as follows:
