Abstract

The purpose is to establish performance requirements and testing methods for active walk-through metal detectors used to find metal weapons and/or metal contraband carried on a person and/or concealed by a non-metal object. The requirements for acceptance include electrical requirements, detection performance specifications, operating requirements, mechanical specifications and requirements, functional requirements, detector mount, quality control and assurance, and documentation. Detection performance specifications include detection sensitivity, speed, repeatability, discrimination, operating controls, environmental ranges and conditions. Performance testing procedures include general test conditions, detection performance tests, alarm indication test, test for operation near a metal wall, steel reinforced floor, or moving metal door, and burn-in test. General test conditions include test location, environment, and preparations. Field testing procedures are for large, medium, and small object size. During field testing procedures, the detector is turned on and a clean tester walks through the detector portal carrying large, medium, and small object size test objects. 22 references
