Compliance overview
Scope and applicability
This standard applies to the design, manufacturing, assembly, acceptance, and use of transmission baggage security inspection systems. It specifically covers micro-dose X-ray equipment where the height and width of any inspection channel entrance are less than 1.1m. It is not applicable to CT scanners, electron accelerator systems, or X-ray devices with energy exceeding 500keV.
Technical requirements
The standard specifies comprehensive performance metrics for transmission baggage security inspection systems, categorized into Class I, II, and III based on capabilities. Key requirements include wire display, penetration resolution, and spatial resolution to ensure accurate threat detection. For multi-energy spectrum devices, it mandates specific capabilities for organic, inorganic, and mixed material differentiation, assigning distinct color codes (e.g., orange, green, blue) to different material types. Manufacturers must ensure the conveyor speed meets the minimum threshold and operates without significant lateral deviation. Additionally, the standard enforces strict radiation safety limits and environmental adaptability criteria, referencing the general requirements outlined in GB 15208.1-2018.
Testing methods
Testing involves using standardized test objects (Test Object A for image resolution and Test Object B for material differentiation) placed within the inspection channel. The methods evaluate the system's ability to visually resolve copper wires, line pairs, and steel steps under X-ray imaging. Tests also measure the single inspection dose and ambient dose equivalent rate using specific scattering bodies to verify radiation safety compliance. Furthermore, conveyor performance and environmental adaptability are assessed according to the procedures defined in GB 15208.1-2018.
FAQs
What products are regulated under GB 15208.2-2018?
GB 15208.2-2018 regulates transmission baggage security inspection systems utilizing micro-dose X-rays, specifically those with inspection channel entrances smaller than 1.1m in height and width.
Are there any updates from the previous version of GB 15208.2-2018?
Yes, this version replaces GB/T 15208.2-2006. It introduces general technical requirements, testing methods, inspection rules, and packaging guidelines, while also updating the specifications for test objects and adding scattering body requirements for radiation testing.
How does GB 15208.2-2018 relate to other standards?
This standard is Part 2 of the GB 15208 series. It extensively references GB 15208.1-2018 for general technical requirements, safety performance, electromagnetic compatibility, and testing methodologies.
