Worldwide Compliance Testing: International SAR Exposure Limits

Worldwide Compliance Testing: International SAR Exposure Limits

SAR measures the rate at which radio frequency (RF) energy is absorbed by the human body. Because RF energy does have an effect on the body, worldwide compliance testing regulations have been set by authorities in each country. These include the Federal Communications Commission (FCC), European Union (EU), Innovation Science and Economic Development Canada (ISED), Australian Communications and Media Authority (ACMA), and Australian Radiation Protection and Nuclear Safety Agency (ARPANSA).

Keep reading to learn everything you need to know about how these worldwide compliance testing regulations affect you as a manufacturer.

International SAR Regulations

It’s important to note that SAR exposure limits vary from country to country. In the US and Canada, mobile devices are required to meet a limit of 1.6 W/Kg measured from 1 g tissue volume. In order for a device to gain FCC or ISED certification and be allowed to be sold in either country, the maximum SAR level cannot exceed this. In the EU, the SAR limit of a device is 2.0 W/Kg measured from 10 g tissue volume. 

The SAR test reports you’ll need for your device will depend on the country or countries your product will be sold in. When it comes to worldwide compliance testing, different countries have different certifications, meaning they require different reports.

If your products require SAR testing, you can find published RF exposure regulations for many countries or contact us for help. Remember that if your product fails to meet SAR regulations in a country or region, you will not have access to that market.


Canada’s requirements are the most precise. The requirements in this country include CE and FCC certification requirements along with requirements of its own. This makes obtaining certification in Canada a little more challenging than in other countries. 

Just like in the US, Canada requires that devices that emit RF energy and operate at or below 6 GHz with a separation distance of up to 20 cm (8.5 inches) between the user and the device undergo SAR testing.
