Specific Absorption Rate (SAR) is a measure which explains how much radio frequency energy is absorbed by the user’s or bystander’s body or head. SAR testing must be done on radio devices that are used closer than 20 cm to the human head or body.
RF exposure evaluations are performed on devices with fixed and/or mobile transmitters that operate on low time average power or are intended to be used at distances with more than 20 cm from the end-user. E.g., Maximum Permissible Exposure (MPE) Evaluations.
We can test the following technologies & products
- 2G, 3G, 4G and 5G (FR1) cellular devices, satellite, TETRA, BLE, VHF, UHF and WLAN devices
- Cellular base station antennas
- Medical, healthcare, military and consumer products
- Animal care (e.g. tracking devices)
SAR Testing Capabilities
- CE, FCC & ISED SAR Testing
- Pre-Compliance Testing
- Head, Body, Extremity Capability
- Whole-Body SAR Measurement
- Test Frequencies between 12-6000MHz
- In Non-Signaling and Signaling Modes
- Dielectric Parameter Validation
- SAR testing from user equipment to large base station antennas size up to 900mm x 1400mm
We are also able to test limb SAR. From 1st July 2020, France requires limb SAR to be tested, in addition to the head and body SAR. Distributors must display SAR values provided by the manufactures of each appliance put on sale from 1st July 2020 at the point of sale or distribution.
Consumer protection has driven an increase in SAR testing and regulations. We at Verkotan are aware of these updated regulations.
Test Facilities
Verkotan’s SAR test facilities are fully equipped with the premier supplier of SAR evaluation systems and government-preferred vendor: SPEAG.
We are using DASY5 SAR test systems with RX 90 robotic arm, equipped with probes, tissue simulants, and multiple different phantoms such as twin SAM, ELI and Base Station Phantoms.
DASY5 is capable of evaluating products for SAR to all the global SAR standards for both head and body-worn devices.
Our testing is carried out according to standards and specifications in the US, Canadian, European, and Japanese markets:
- US – FCC Knowledge Database Publications on RF Exposure
- Canada – RSS-102, SPR-002
- EU – EN 50357, EN 50360, EN 50383, EN 50385, EN 50566, EN 62209-1, EN 62209-2, EN 62232, EN 62311, EN 62479
- International – IEC 62209-1, IEC 62209-2, IEC 62311, IEEE 1528

Four ways to show RF exposure compliance
Electromagnetic radiation is emitted from various natural and man-made sources. For example, electromagnetic radiation emitted from the sun keeps us warm and electromagnetic radiation emitted from the mobile phones enables wireless communication. But how is the radio frequency (RF) exposure of these wireless devices measured? Continue reading to find out. Read more
