SAR compliance testing can be complicated. Failing compliance testing can result in product redesigns, delayed time to market, and increased cost of development. Understandably, these are things that every wireless device manufacturer would like to avoid, but what can be done? 

Pre-compliance SAR testing is the answer. When you work with a lab to conduct pre-compliance testing, you can determine if your device will pass SAR testing and if it has any issues that need to be addressed. Overall, this will save your business both time and money. Keep reading to learn everything you need to know about pre-compliance testing. 

SAR Compliance Testing

SAR stands for Specific Absorption Rate, and it’s a unit of measurement for the quantity of Radio Frequency (RF) energy absorbed by the body. SAR describes both the amount of RF energy absorbed by the body and the rate at which it’s absorbed by exposed tissue. Keep in mind that this is only measured in devices used within 20 cm (~8 inches) of the body. SAR compliance testing provides a clear-cut way to measure the RF exposure characteristics of wireless devices to ensure that they meet FCC regulations.

SAR value is indicated by watts per kilogram (W/kg) or milliwatts per gram (mW/g). RF exposure is a measure of both the electric and magnetic field strength and power density for transmitters operating at frequencies ranging from 300 kilohertz (kHz) to 100 gigahertz (GHz). 

Wireless devices are required to be evaluated to meet the RF exposure limits that have been determined by the FCC and other federal governmental agencies around the world. When a device proves compliance, this means that the device will not expose users to levels of RF exposure higher than what is allowed by regulatory guidelines.

Pre-Compliance Testing

SAR compliance testing is required to be conducted at the end of the development process. However, when a wireless device is designed and developed without input from anyone with knowledge of SAR regulations, you may end up with a device that will fail the testing process. Once this happens, the only thing that can be done is to completely redesign the device, as proof of compliance is required to sell these devices.

Fortunately, all of this can be avoided with pre-compliance SAR testing. This entails testing during the product development phase as well as working with a SAR testing lab to get guidance on the product’s design. 

Pre-compliance SAR testing can help you save time and money by helping you determine if a product will pass testing throughout the design and development process. If you find that there are any issues with the product, you can quickly correct them without significant loss of time or money. Although pre-compliance testing can result in slightly increased costs, the benefits it provides, and the time and money it will save your business, make up for these added costs.
