|Title:||The National Institute of Justice Standards for Hand-Held and Walk-Through Metal Detectors Used in Concealed Weapon and Contraband Detection|
|Published:||January 01, 2003|
|Abstract:||The National Institute of Justice (NIJ) standards for hand-held and walk-through metal detectors were initially published in 1974 and later revised in 2000 and 2002 to accommodate the improvements in metal detector design and component technology and to address the concerns of the criminal justice, law enforcement, and corrections (CJLEC) agencies regarding detection performance, device quality and reliability, and system operation. This paper describes the 2000 and 2002 NIJ standards and how they address the new technolgoy and CJLEC agency concerns. The 1974 standards did not contain requirements for interference, durability, environmental tolerance, and certain detection performance specifications, which were introduced in the 2000 standards. New test objects and dector classifications were also introduced in the 2000 standards. The electromagnetic interference (EMI) requirements given in the 2000 standards were changed in the 2002 standards. The 2002 standards also require the use of slightly different test objects and procedures.|
