IEC/SC 77A develops ISO standards in the area of Information technology. The scope of work includes: Standardization in the field of electromagnetic compatibility with regard to low frequency phenomena (ca Note: This limit frequency can be adapted to a higher frequency according to the phenomena or equipment Currently, there are 81 published standards from this subcommittee.
The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.
A Subcommittee (SC) in ISO operates under a Technical Committee and focuses on a specific subset of the TC's scope. Subcommittees develop standards and technical specifications in their specialized area, reporting to their parent Technical Committee. They may also have working groups for detailed technical work.
