March 21, 2002 tests results:

On March 21, 2002 additional testing was conducted to supplement the data documented in test report FSSS10002-0 " Fixed Security Screening System FSSS Validation Testing: Phase 1 of 4". The testing methodology was modified to evaluate the system performance when attempts were made to conceal the explosive targets by adding items to the suitcase.

One hundred integrations were performed using two different explosive types providing 200 opportunities to identify an explosive target. The targets were successfully identified 200 times out of the 200 opportunities. There were six (6) re-shoot signals received when the C4 target was used and eight (8) re-shoot signals received when the TNT target was used. Each re-shoot signal was followed by an explosive signal for a 100% accuracy rate.

Twenty additional integrations were taken on the suitcase in areas void of an explosive target i.e. outside the range of the single detector-single source configuration but placing other items such as the ammonia cleaner within the field of view of the detector. No explosives indications were received confirming that no "false positives" would be obtained under the conditions this test was performed.
