Harmonization of Performance Standards for Diagnostic X-Ray Imaging Systems and Components with IEC Standards

This guidance addresses diagnostic x-ray imaging systems and their major components that are classified as Class I or II medical devices. It aims to harmonize FDA's EPRC (Electronic Product Radiation Control) performance standards with IEC standards to ensure efficient and consistent regulatory review of these products. The guidance covers various x-ray imaging devices including radiographic, fluoroscopic, mammographic, dental, and computed tomography systems.

  1. Determine applicable IEC standards for your specific device type using the guidance’s appendix
  2. Implement testing program to demonstrate conformance with applicable IEC standards
  3. Prepare and maintain declaration of conformity documentation
  4. Create and affix appropriate certification label
  5. Develop and provide AIAT documentation including Radiation Safety Specification and Testing Comparison Document
  6. Establish quality system procedures for:
    • Design controls
    • Testing documentation
    • Records maintenance
    • Defect reporting and correction
  7. Implement procedures for:
    • Accidental radiation occurrence reporting
    • Defect notification
    • Corrective actions
  8. Ensure compliance with both medical device and electronic product regulations
  9. Maintain all required documentation and records for FDA inspection
  10. Provide necessary information to assemblers and other personnel

Key Considerations

Non-clinical testing

  • Testing must be based upon individual article testing or testing program in accordance with good manufacturing practice
  • Testing results must be documented and placed in firm’s records
  • Quality system must address radiation safety and conformity through design controls

Labelling

  • Certification label must be permanently affixed and legible
  • Label must be in English language
  • Must include modified statement of compliance with specific IEC standards
  • Must provide instructions for assembly, installation, adjustment and testing (AIAT)
  • Must include Radiation Safety Specification and Testing Comparison Document

Safety

  • Must comply with radiation safety specifications
  • Must provide protection from hazardous and unnecessary radiation exposure
  • Must maintain records of accidental radiation occurrences
  • Must notify FDA of radiation safety defects
  • Must implement corrective actions for defects

Other considerations

  • IEC 60601-1-3: Medical electrical equipment – Collateral Standard: Radiation protection in diagnostic X-ray equipment
  • IEC 60601-2-28: Medical electrical equipment - Particular requirements for X-ray tube assemblies
  • IEC 60601-2-43: Medical electrical equipment – Particular requirements for X-ray equipment for interventional procedures
  • IEC 60601-2-44: Medical electrical equipment – Particular requirements for X-ray equipment for computed tomography
  • IEC 60601-2-45: Medical electrical equipment – Particular requirements for mammographic X-ray equipment
  • IEC 60601-2-54: Medical electrical equipment – Particular requirements for X-ray equipment for radiography and radioscopy
  • IEC 60601-2-63: Medical electrical equipment – Particular requirements for dental extra-oral X-ray equipment
  • IEC 60601-2-65: Medical electrical equipment – Particular requirements for dental intra-oral X-ray equipment
