SAR and RF exposure testing
SAR testing ensures the safety of radio products by measuring the RF energy absorbed by the body, ensuring devices meet exposure limits for user and manufacturer peace of mind.
At RadioPark, with over 15 years of experience in RF exposure evaluations and SAR testing, we specialize in helping companies navigate the complexities of RF safety. Our expert team ensures precise testing for SAR compliance, helping your products meet strict safety standards and RF exposure limits.
What is SAR Testing?
Specific Absorption Rate (SAR) testing is essential for measuring the amount of radiofrequency (RF) energy absorbed by the human body when using a device. It ensures that devices such as mobile phones, medical equipment, and various wireless products comply with strict RF exposure limits set by regulatory authorities. These limits vary by region, but SAR testing ensures that a device will not cause harmful exposure to its users or those nearby.
Why is SAR Testing Important?
In order to safeguard users from excessive RF exposure, SAR testing verifies that a device meets the required safety standards. This process is critical for ensuring that products conform to the safety regulations set by organizations such as the CE, FCC, and ISED. Without SAR testing, manufacturers risk non-compliance and potential harm to users, making it an indispensable step in product development.

Frequently Asked Questions about SAR and RF Exposure Testing
-
What is the difference between RF Exposure Evaluation and SAR testing?
RF Exposure Evaluation involves reviewing the technical details of a device and calculating the potential RF exposure, while SAR testing directly measures how much RF energy is absorbed by the body when using the device. SAR testing is required in cases where RF Exposure Evaluation is insufficient.
-
Do I need SAR testing for every device I produce?
No, SAR testing is only required for devices that are used close to the body or when the combined power of all radios in the device exceeds certain thresholds. RF Exposure Evaluation may be enough in other cases, especially when the device is used more than 20 cm away from the body.
-
What regions require SAR testing?
SAR testing is required for compliance with regulations in multiple regions, including Europe (CE), North America (FCC and ISED), and many other global markets. Each region has its own RF exposure limits, so testing must meet the specific standards applicable to the target market.
-
ow long does SAR testing take?
The duration of SAR testing depends on the complexity of the device and the tests required. Our team ensures efficient processing to meet your deadlines and regulatory requirements.
