Description / Abstract:
This standard is intended to be used to determine the imaging
performance of x-ray and gamma-ray systems utilized to inspect
loaded or empty vehicles, including personal and commercial
vehicles of any type; marine and air cargo containers of any size;
railroad cars; and palletized or unpalletized cargo larger than 1 m
× 1 m in cross-section. The standard applies to systems that are
the following:
— Single or multiple energy, source, or view
— Employ primary (i.e., transmission) and/or scatter (e.g.,
backscatter) radiation detection
— Used to detect prohibited and controlled materials and/or to
verify manifests
—Primarily imaging systems but also may have complementary
features such as material discrimination and automatic active or
passive threat alerts. This standard does not address how to test
these complementary features.
Adherence to all applicable mechanical and electrical safety
requirements and compatibility with all applicable installation
codes, including electro-magnetic compatibility requirements, is
extremely important for any type of x-ray or gamma-ray screening
system; however, identification of these requirements is not within
the scope of this standard.
Purpose
The purpose of this document is to provide standard, repeatable
and verifiable methods to describe and measure the imaging
performance characteristics of the systems listed above. It is not
intended to determine the capability of a security screening system
under specific operational inspection conditions.
