Escopo e aplicabilidade

This standard applies to the design, manufacture, and inspection of portable X-ray security inspection equipment. It categorizes equipment into indoor and outdoor types, as well as single-energy and multi-energy spectrum types. It is not applicable to portable X-ray equipment based on backscatter technology. Manufacturers of security screening devices must ensure compliance with these mandatory specifications.

Requisitos técnicos

The standard specifies comprehensive requirements across several domains. For physical construction, it mandates specific enclosure protection ratings (e.g., IP20 for indoor, IP52 for outdoor) and robust structural integrity for handles and cables. Regarding power supply, it outlines strict adaptability for both AC and battery operations, requiring lithium batteries to comply with GB 31241. Manufacturers must implement reliable power management and anti-reverse connection designs. For radiation protection, the standard sets strict limits on leakage radiation and scattered radiation to ensure operator safety. Functional requirements dictate that devices must have clear visual and audible status indicators, advanced image processing capabilities (including zoom and enhancement), and secure image storage for at least 10,000 images. Equipment must also feature a self-diagnostic function to report the status of critical components. The performance metrics section defines minimum thresholds for penetration power, wire resolution, spatial resolution, and material discrimination. Additionally, the standard covers environmental adaptability and electromagnetic compatibility (EMC), ensuring the device operates reliably under varying climatic, mechanical, and electromagnetic conditions.

Métodos de ensaio

Testing procedures involve evaluating environmental adaptability using methods referenced in the GB/T 2423 series for temperature, humidity, vibration, and shock. EMC testing follows the GB/T 17626 series for immunity against electrostatic discharge and RF fields. Performance metrics such as penetration and resolution are verified using specific test blocks detailed in the normative appendix. Engineers must use the prescribed test apparatus to accurately measure radiation leakage and image quality.

Perguntas frequentes

What products are regulated under GB 12664-2024?

It regulates portable X-ray security inspection equipment used for on-site security checks. It explicitly excludes devices using X-ray backscatter technology.

Are there specific battery requirements in this standard?

Yes, equipment using lithium batteries must comply with GB 31241. The standard also requires anti-reverse connection designs and sufficient capacity for at least 100 continuous image acquisitions.

What are the enclosure protection requirements?

Indoor-type equipment must meet at least IP20, while outdoor-type equipment must meet at least IP52 as defined in GB/T 4208-2017.
