本标准旨在确定x射线和伽马射线的成像性能 用于检查装载或空载车辆的系统，包括任何类型的个人和商用车辆；任何尺寸的海运和空运集装箱；火车车厢；以及每天超过1米的托盘或非托盘货物？横截面为1米。本标准适用于以下系统: --单个或多个能量、源或视图 --采用初级（即传输）和/或散射（例如后向散射）辐射检测 --用于检测禁用和受控材料和/或验证舱单 --主要是成像系统，但也可能具有互补功能，如材料识别和自动主动或被动威胁警报。本标准不涉及如何测试这些补充特性。 遵守所有适用的机械和电气安全要求以及与所有适用安装规范的兼容性，包括电磁兼容性要求，对于任何类型的x射线或伽马射线极为重要- 射线筛查系统；然而，这些要求的识别不在本标准的范围内。

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.
