1、Designation: F3278 17Standard Performance Specification forHand-Held Metal Detectors Used in Safety and Security1This standard is issued under the fixed designation F3278; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of
2、 last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This performance specification applies to all hand-heldmetal detectors (HHMDs) used to find metal contrabandconcealed
3、 or hidden on people or other objects with accessiblesurfaces. This performance specification describes baselineperformance requirements, which includes metal object detec-tion performance, safety (electrical, mechanical, fire), electro-magnetic compatibility, environmental conditions and ranges,and
4、 mechanical durability. The requirements for metal detec-tion performance are unique and, therefore, test methods forthese parameters are provided, including the design of testobjects. An agency or organization using this performancespecification is encouraged to add their unique operationally-based
5、 requirements to those requirements listed in this baselineperformance specification.1.2 This performance specification describes the use ofspherical test objects, instead of actual threat objects orexemplars of threat objects, to test the detection performanceof hand-held metal detectors. Spherical
6、 test objects are usedbecause the detectability of spherical test objects is notorientation dependent, whereas this is not true for non-spherical test objects. This orientation-dependent detectabilityof non-spherical test objects may allow a HHMD to beincorrectly attributed a higher performance capa
7、bility than thatHHMD is capable of providing. To aid agencies wishing to addspecific threat objects to their detection performancerequirements, included in Annex A1 is the analysis of theprobability of detection for different orientations of agency-specific threat objects.1.3 This standard does not
8、purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international sta
9、ndard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.2.
