Overview
IEC 62963:2020 is an international standard published by the International Electrotechnical Commission (IEC) that specifies the technical requirements and performance criteria for X-ray computed tomography (CT) inspection systems used in the security inspection of bottled or canned liquids. This standard is specifically tailored to systems employing tomographic scanning techniques rather than conventional X-ray projection methods. The scope of IEC 62963:2020 encompasses the inspection of liquids, aerosols, and gelatinous substances contained within transparent or visually opaque bottles and cans.
This standard addresses multiple facets of these CT inspection systems, including their structure, functionality, radiation safety, electrical and mechanical safety, environmental resilience, electromagnetic compatibility, and documentation requirements. Additionally, IEC 62963:2020 provides guidance on testing methods, inspection criteria, labelling, packaging, shipping, and storage of such systems. It establishes baseline technical and performance benchmarks essential for manufacturers and regulators involved in radiation protection instrumentation for bottled/canned liquids inspection.
Key Topics
-
Technical and Performance Requirements
Defining minimum standards for CT inspection systems to ensure reliable detection and image quality, including contrast sensitivity and spatial resolution tests.
-
Radiation Protection and Safety
Specifications to safeguard operators and the environment from harmful radiation exposure, with compliance to ambient dose equivalent limits.
-
Electrical and Mechanical Safety
Guidelines on electrical safety compatible with measurement and control equipment standards, plus mechanical robustness to withstand operational stresses.
-
Environmental and Electromagnetic Compatibility
Requirements for systems to function correctly under various environmental conditions (temperature, humidity, vibration) and to maintain immunity against electromagnetic interference.
-
Markings, Labelling, and Documentation
Standardized labeling and comprehensive documentation obligations covering user manuals, safety warnings, and calibration certificates.
-
Packaging, Shipping, and Storage
Instructions for secure packaging and handling to prevent damage during transportation and storage.
-
Test Methods and Inspection
Detailed reference procedures for conducting technical performance tests such as contrast-sensitivity evaluations and spatial resolution assessments using standardized test articles.
Applications
IEC 62963:2020 is primarily applicable to the design, manufacture, installation, and regulatory approval of X-ray CT inspection systems at security checkpoints, manufacturing quality controls, and inspection facilities focusing on bottled and canned liquids. Practical applications include:
-
Airport and Border Security
Inspecting liquids for hidden threats or contraband using advanced CT scanning for higher resolution imaging beyond conventional X-ray projections.
-
Food and Beverage Industry Quality Control
Non-destructive testing of beverages and liquid products in opaque or transparent containers to detect foreign objects, contamination, or packaging defects.
-
Hazardous Materials Screening
Checking aerosols and gelatinous substances in sealed containers for security threats in public transportation and sensitive environments.
Compliance with IEC 62963:2020 facilitates uniform assessment criteria for these CT systems, ensuring safety, reliability, accuracy, and interoperability across international borders.
Related Standards
IEC 62963:2020 references and complements several international standards that govern environmental testing, electrical and machinery safety, and electromagnetic compatibility, including:
- IEC 60068 Series – Environmental Testing (Cold, Dry Heat, Vibration, Damp Heat)
- IEC 60529 – Degrees of Protection Provided by Enclosures (IP Code)
- IEC 61010-1 – Safety Requirements for Electrical Equipment for Measurement and Control
- IEC 61000-6-1 and IEC 61000-6-3 – Electromagnetic Compatibility Standards
- ISO 780:2015 – Packaging – Graphical Symbols for Handling and Storage
- ISO 13849 – Safety of Machinery – Safety-Related Control Systems
These standards provide essential foundations and complementary requirements that ensure the CT inspection systems are tested for environmental resilience, operational safety, and electromagnetic compatibility according to global best practices.
Enhancing radiation protection instrumentation, IEC 62963:2020 empowers manufacturers and regulatory bodies to deploy advanced X-ray CT inspection systems that are safe, effective, and consistent worldwide for the critical task of bottled and canned liquid security inspection.
