Specific Absorption Rate (SAR) Testing

Ensure your wireless devices adhere to SAR standards to gain access to global markets. Element’s specialized Specific Absorption Rate (SAR) services will help you comply with international regulations. As a global leader in RF Exposure assessments, our capabilities include Power Density (PD) and SPR-002 Nerve Stimulation Testing for comprehensive RF safety compliance.

What is Specific Absorption Rate (SAR) testing and why is it important? 

Specific Absorption Rate (SAR) is the measure of how much Radio Frequency (RF) energy from wireless devices is absorbed by the human body. Governments worldwide enforce safety guidelines, limiting RF exposure within 20 cm (7.8 in) of the head or body. SAR testing ensures compliance with these guidelines and helps ensure the safety and well-being of your customers. This mandatory approach safeguards public health and promotes the responsible development and usage of wireless communication technologies.

How is Element’s SAR testing conducted?

SAR testing at Element uses the highly advanced DASY6 scanning system, for the latest technology in SAR testing. This involves placing your wireless device next to a “phantom” (a simulated model of a human body part, such as a head, torso, wrist or hand). Your device is then operated at its maximum power levels while SAR probes measure the energy absorbed by different body tissues. The results are used to calculate the SAR values. These values can be used to ensure devices comply with exposure limits, such as the SAR limit of 1.6 W/kg for the general population in the US and Canada, regulated by 47 CFR Part 2, section 2.1093. The European Union and other countries have a SAR limit of 2.0 W/kg under Council Recommendation 1999/519/EC. Similar tests can also be conducted using DASY6 and phantoms to assess Power Density (PD) levels.

Key benefits of Specific Absorption Rate testing with Element

• Ensure Regulatory Compliance: Our SAR testing service guarantees that your wireless devices meet established regulatory limits. The testing process provides essential data demonstrating your devices' compliance with safety standards, streamlining the certification and regulatory approval process for you.
• Remain Accountable: As a manufacturer, uphold your accountability through independent verification using our SAR testing procedure. This allows you to assess and showcase your products' adherence to specific standards, providing an objective and standardized method to identify and address potential issues related to RF energy absorption.
• Achieve Global Market Access: SAR testing facilitates your product's global market access by providing evidence of compliance with international SAR standards including those for the US, Canada, Korea, Japan, and Europe, simplifying the certification processes necessary for your products to enter the global market.
• Optimize Your Network: To optimize the network integration of your products, SAR testing offers crucial information about RF energy absorption by the human body during device usage. This data assists you in optimizing network performance (considering factors such as placement, and supportive or shielding devices) and addressing potential issues related to device interaction within the network.
• One supplier, One solution: Our expert engineers can arrange Power Density (PD) testing, as well as SPR-002 Nerve Stimulation testing, alongside or separately from SAR testing – providing the convenience of complete compliance through one supplier, reducing time to market and unnecessary costs. Element is also a global leader in a wide range of other EMC and Global Market Access services and our team is happy to discuss your individual needs.
