L-3 eXaminer XLB Explosives Detection System Receives New EU Standard 3 Approval

WOBURN, Mass. – L-3 Security & Detection Systems announced today that its eXaminer® XLB explosives detection system (EDS) has passed the European Union Commission Regulation Standard 3 for Aviation Safety under the European Civil Aviation Conference (ECAC) Common Evaluation Programme of Security Equipment (CEP). The system was successfully tested by the Service Technique de l’Aviation Civile (STAC), the engineering department of France’s aviation regulatory agency.

The eXaminer XLB is the first high-speed CT EDS to achieve EU Standard 3 approval under the new CEP and delivers operational throughput greater than 1,200 bags per hour.

“The eXaminer XLB is the highest-performing in-line CT EDS available and the only EU Standard 3 system with sufficient throughput for European Level 1 operation,” said Thomas M. Ripp, president of L-3 Security & Detection Systems. “We continue to invest in the eXaminer platform to meet current and future EU standards.”

Featuring a meter-wide tunnel, the eXaminer XLB generates high-resolution 3-D image data for explosives detection by combining helical CT with dual-energy imaging. Using 3-D Continuous Flow CT technology, the system generates high-resolution medical quality images in real time. With advanced tools that include 360-degree rotational views of entire bags and individual threat objects, operators can quickly and confidently clear bags for flight or designate bags for search.

Since 1998, L-3 has used medical-grade imaging technology developed for aviation security with an understanding of the complex demands faced by airport personnel and regulatory agencies around the globe. Nearly 1,000 eXaminer systems have been deployed at airports domestically and internationally and supported by L-3’s world- service organization.
