1、Designation: F3020 16Performance Standard forHand-Worn Metal Detectors Used in Safety and Security1This standard is issued under the fixed designation F3020; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision
2、. 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 standard applies to all hand-worn or glove-typemetal detectors used to find metal contraband concealed orhidden on people or o
3、ther objects with hand-accessible sur-faces. Hand-worn metal detectors (HWMDs) are significantlydifferent in design compared to the more common hand-heldmetal detector (HHMD). For example, the HWMD generates amuch more localized magnetic field than does the HHMD andthe useful field of the HWMD is no
4、rmal to the plane of thehand whereas the useful field of the HHMD is multi-directional.1.2 This standard describes minimally acceptable perfor-mance requirements, which includes metal object detectionperformance, safety (electrical, mechanical, fire), electromag-netic compatibility, environmental co
5、nditions and ranges, andmechanical durability. The requirements for metal detectionperformance are unique and, therefore, test methods for theseparameters are provided, including the design of test objects.An agency or organization using this standard is encouraged toadd their unique operationally-b
6、ased requirements to thoserequirements listed in this minimally-acceptable performancestandard.1.3 This documentary standard describes the use of spheri-cal test objects, instead of actual threat objects or exemplars ofthreat objects, to test the detection performance of hand-wornmetal detectors. Sp
7、herical test objects are used because thedetectability of spherical test objects is not orientationdependent, whereas this is not true for non-spherical testobjects. This orientation-dependent detectability of non-spherical test objects may allow a HWMD to be incorrectlyattributed a higher performan
8、ce capability than that HWMD iscapable of providing. To aid agencies wishing to add specificthreat objects to their detection performance requirements,included in Annex A1 is the analysis of the probability ofdetection for different orientations of agency-specific non-spherical threat objects.1.4 Th
9、is standard does not 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.
