When it comes to RF and SAR testing, there are some existing misconceptions that can be a source of confusion for manufacturers. These tests are essential for ensuring the safety and compliance of devices that emit RF energy, but misinformation can cloud their importance. In this article, we’ll debunk common myths surrounding SAR and RF testing, provide accurate information, and help manufacturers understand the realities of the testing process to ensure their products meet regulatory standards and keep users safe.

SAR testing isn’t necessary for low-power devices

The reality is that even low-power devices like wearables or IoT gadgets emit RF energy if they function wirelessly. SAR testing ensures that these devices comply with safety standards, especially since many are used in close contact with the body.

SAR and RF testing are the same

The truth is that SAR testing measures the RF energy absorbed by the body, while RF testing focuses on the device’s electromagnetic emissions. Both are critical but serve different safety and performance functions.

As long as a device passes testing in one country, it’s fine everywhere

SAR limits vary by country and region. For example, the FCC sets a SAR limit of 1.6 W/kg over 1 gram of tissue, while the EU limit is 2.0 W/kg over 10 grams of tissue. Each region has specific regulations.

Devices always pass testing on the first try

Many devices need design adjustments after initial testing to meet SAR and RF compliance. Pre-compliance testing during development helps identify issues early, which can prevent design or other issues that may lead to test failure.

If a device passes RF testing, SAR testing is unnecessary

RF testing verifies emissions, while SAR testing assesses human exposure. A device can pass RF tests and still fail SAR testing if it emits too much energy near the body.

SAR testing only applies to phones

SAR testing is required for all devices containing a transmitter, including tablets, laptops, smartwatches, wireless headsets, medical devices, and more to ensure safety in close contact with users.

Devices always emit RF energy at maximum levels

Devices often adjust power levels based on usage conditions. SAR testing covers a range of operating conditions, ensuring safety under both low and high power levels.

Older Devices Don’t Need Retesting

If a device’s components, antennas, or software are updated, retesting may be required to ensure continued compliance with SAR and RF standards.
