Compliance overview
Scope and applicability
This standard applies to the design, manufacturing, assembly, acceptance, and use of transmission cargo security inspection systems. Specifically, it regulates micro-dose X-ray equipment where the maximum single edge length of the inspection channel entrance cross-section ranges from 0.91m to 2.41m. This standard is mandatory for all manufacturers of large-scale cargo X-ray scanners. It does not apply to Computer Tomography (CT) systems, electron accelerator equipment, X-ray devices with energy exceeding 500keV, or vehicle security inspection systems.
Technical requirements
The standard categorizes equipment into five types (Type I to V) based on the maximum single edge dimension of the inspection channel. It mandates strict performance metrics, including wire resolution, penetration resolution, and spatial resolution limits, which vary according to the equipment type. The equipment must accurately distinguish and color-code organic, mixture, and inorganic materials using specific saturated colors (orange, green, and blue respectively). Furthermore, the conveyor device must meet minimum speed requirements and possess specific load-bearing capacities depending on the equipment class. Manufacturers must ensure their systems meet these exact imaging and mechanical thresholds.
Testing methods
Testing involves the use of specialized Test Body A (for penetration force) and Test Body B (a comprehensive tester for resolution and material discrimination). The standard outlines visual evaluation procedures of X-ray images generated from these test bodies placed at specific positions within the inspection channel. Additionally, it references radiation testing methodologies, such as measuring the single inspection dose and ambient dose equivalent rate using designated scatter bodies, as defined in the parent standard GB 15208.1-2018. Compliance verification requires rigorous testing across multiple channel locations.
FAQs
What products are regulated under GB 15208.3-2018?
It regulates transmission cargo security inspection systems where the maximum single edge length of the inspection channel entrance cross-section is between 0.91m and 2.41m. It does not apply to CT scanners, electron accelerator systems, devices with X-ray energy >500keV, or vehicle inspection equipment.
How does GB 15208.3-2018 relate to other parts of the GB 15208 series?
It is part of the GB 15208 series. While Part 1 covers general technical requirements and Part 2 covers baggage scanners, Part 3 specifically addresses large-scale cargo inspection systems, introducing unique performance metrics like higher conveyor load capacities and specific penetration force thresholds.
Is compliance with GB 15208.3-2018 mandatory for market access?
Yes, all technical content in this standard is mandatory. Manufacturers must ensure their cargo inspection systems meet the specified performance, radiation safety, and environmental requirements before market entry.
