SAR Testing

Overview

Government agencies around the world are increasingly focused on the health and safety impact of products using RF transmitters. Manufacturers of wireless devices are required to demonstrate their products' compliance with the RF exposure limits set forth in national specific absorption rate (SAR) regulations. UL tests to all current SAR standards. We can analyze devices at any and all stages of the product development cycle to help manufacturers speedily bring their compliant products to the global market.

Definition

SAR testing measures the electromagnetic energy absorbed by a body using a wireless device. SAR testing is intended to verify that a device does not exceed a country’s established RF exposure limits.

Benefits

UL provides our customers with expert technical advice, project management and conformance testing to help ensure that products meet essential market requirements.

We perform SAR testing to all world standards, for all devices requiring CE, FCC, IC and Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) approvals. Our comprehensive expertise, based on more than 10 years of experience in SAR testing, not only helps our customers launch RF products quickly and efficiently, but also helps to eliminate the possibility of recalls.

Using state-of-the-art SAR testing equipment enables UL to assist our customers at any stage of the development cycle, mitigating the risk of discovering a product is noncompliant just prior to its planned launch.

Our qualified test facilities around the world enable UL to provide services in our customers’ own time zones and languages.

UL’s presence on technical committees helps to guarantee that we remain up to date with the latest international standards and drafts, including the regular updates applied to the FCC Knowledge Database and Permit-But-Ask procedures and requirements.
