TU‐G‐213‐02: IEC Subcommittee 62B (Diagnostic Imaging Equipment): Recent and Active Projects
The International Electrotechnical Commission (IEC) writes standards that manufacturers of electrical equipment must comply with. Medical electrical equipment, such as medical imaging, radiation therapy, and radiation
dosimetry devices, fall under Technical Committee 62. Of particular interest to medical physicists are the standards developed within Subcommittees (SC) 62B, which addresses diagnostic radiological imaging equipment, and 62C, which addresses equipment for radiation therapy, nuclear medicine and dosimetry. For example, a Working Group of SC 62B is responsible for safety and quality assurance standards for CT scanners and a Working Group of SC 62C is responsible for standards that set requirements for dosimetric
safety and accuracy of linacs and proton accelerators. IEC standards thus have an impact on every aspect of a medical physicist’s job, including equipment testing, shielding design, room layout, and workflow. Consequently, it is imperative that US
medical physicists know about existing standards, as well as have input on those under development or undergoing revision.
The structure of the IEC and current standards development work will be described in detail. The presentation will explain how US
medical physicists can learn about IEC standards and contribute to their development.
Learning Objectives:
1. 
Learn about the structure of the IEC and the influence that IEC standards have on the design of equipment for radiology and radiation therapy.
2. 
Learn about the mechanisms by which the US participates in the development and revision of standards.
3. 
Understand the specific requirements of several standards having direct relevance to diagnostic and radiation therapy physicists.
