Under no circumstances will S21 be held liable for any loss, injury or damage associated with the use of this data. You should also be aware that the SAR values shown are maximum values and in practice emissions from mobile phones will normally be lower than these figures.

The emissions depend on factors such as distance from a transmission mast, whether the phone is used indoors or outdoors, how close the phone is held to the ear and other operating factors.

It is important to realise that a phone with a high SAR rating may actually operate with much lower emissions in practice, and conversely a phone with a lower SAR rating may operate with emissions higher than a high SAR phone in practice.

You should not rely on a low SAR rating to guarantee your health. Comment by Abinashkumar from India on 24th Sep What about tenor e mobile phones?

The A3 as you can see in the samsung website in the sar page, was measured at the right distance of 0,5cm, that is why its body sar eu appears to be high and it is high.

However, this measurement, even though it is high, it is accurate. The other measurement of the a3 is essentially non-valid.

This is High. This means that essentially, the a3 has a higher body eu sar than the a3 ! It is usually mentioned below or after the sar measurement.

And for the US sars they measure at 1cm or 10mm which is ok. Samsung tests the US sar of some of their phones at 1. The samsung and LG are just examples.
