Scope

This document establishes standards for the technical performance of cabinet x-ray imaging systems used for screening at security checkpoints and other inspection venues. Included are all x-ray systems designed primarily for the inspection of baggage at airline, railroad, and bus terminals, and in similar facilities. An xray tube used within a shielded part of a building, or x-ray equipment that may temporarily or occasionally incorporate portable shielding, is not considered to be a cabinet x-ray system. Hereinafter, systems covered by the scope of this standard are referred to as the system. This standard applies to x-ray imaging equipment with all of the following characteristics: -Meet the definition of cabinet x-ray systems as given in 21 CFR 1020.40 -Operate at or above 120 kV -Have tunnel nominal dimensions of up to 1.1 m × 1.1 m -Provide a single-view direct-projection image as the primary image -Are used to examine items to detect prohibited and illicit materials at security-checkpoint locations (e.g., airports, seaports, land border crossings, office buildings, court houses, correctional institutions, nuclear power facilities, military facilities, commercial shipping and receiving stations, stations used for manifest verification) For further clarification, systems included in this standard can be those with or without organic/inorganic differentiation, with or without active or passive threat alerts, and those incorporating multi-view and computed-tomography (CT) imaging (if the primary image presented is a single-view projection image), if they have all of the characteristics found in the list above. This standard therefore is not intended for x-ray imaging systems with any of the following characteristics: -Operate at potentials that are less than 120 kV -Are not cabinet systems (e.g., open bomb-squad systems) -Do not present a direct-projection image -Can provide a projection image only through image reconstruction from multiple views -Are based primarily on the use of CT -Are used for medical diagnostic imaging -Are used for non-destructive evaluation (NDE) or non-destructive testing (NDT), industrial quality control (e.g., food inspection), industrial sortation of recyclables or natural resource extraction, systems used for scientific research purposes -Are based only on backscattered or coherently scattered x-rays This standard specifies minimum requirements and test procedures for x-ray imaging performance, radiation-limitation requirements, and electrical, mechanical, and environmental requirements. This standard addresses technical image-quality performance, not threat-detection performance.
