ASTM C1270-97(2021)

1.1''This practice covers a procedure for determining the weakest detection path through the portal aperture and the worst-case orthogonal orientation of metallic test objects. It results in detection sensitivity maps, which model the detection zone in terms related to detection sensitivity and identify the weakest detection paths. Detection sensitivity maps support sensitivity adjustment and performance evaluation procedures (see Practices C1269 and C1309).

1.2''This practice is one of several developed to assist operators of walk-through metal detectors with meeting the metal detection performance requirements of the responsible regulatory authority. (See Appendix X2)

1.3''This practice is neither intended to set performance levels, nor limit or constrain operational technologies.

1.4''This practice does not address safety or operational issues associated with the use of walk-through metal detectors.

1.5''The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.6''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.
