【国外标准】 Standard Guide for Installation of Walk-Through Metal Detectors

4.1 This guide is intended for use by the designers, evaluators, and users of walk-through metal detectors to be installed to screen persons entering or leaving a controlled access area. This guide is not meant to constrain design liberty but is to be used as a guide in the selection of location and installation of walk-through metal detectors.1.1 Some facilities require that personnel entering designated areas be screened for concealed weapons and other metallic materials. Also, personnel exiting designated areas are often screened for metallic shielding material and other types of metallic contraband. Walk-through metal detectors are widely used to implement these requirements. This guide describes various elements to be considered when planning to install walk-through metal detectors.1.2 This guide is not intended to set performance levels, nor is it intended to limit or constrain operational technologies.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
