Evaluating X-Ray System Performance: Standard Practice by ASTM International

This standard covers all X-ray screening systems, up to 1m wide by 1m high, including explosives detection systems, producing projection or projection/scatter images. It's applicable to X-ray systems screening baggage, packages, cargo, or mail for prohibited items like weapons and explosives. It outlines quantitative and qualitative evaluation methods, without setting specific performance requirements. It employs three standard test objects: HP for human perception, RT for routine testing, and OE for objective evaluation, each detailed within the standard.

• Purpose and Applicability: This practice applies to X-ray systems with specific dimensions and usage
• Purpose and Usage: This standard is for screening systems used in various contexts
• Test Objects: Three standard test objects are used for different evaluations
• Standardization Process: This international standard was developed following recognized principles
• Safety Considerations: Users must establish safety practices and determine regulatory limitations
