IEC/SC 77B - High frequency phenomena
Standardization in the field of electromagnetic compatibility with regard to high frequency continuous and transient phenomena (ca > 9 kHz, see Note). Note: This limit frequency can be adapted toward a lower or higher frequency according to the phenomena or equipment.
Phénomènes haute fréquence
Normalisation dans le domaine de la compatibilité électromagnétique concernant les phénomènes continus et transitoires à hautes fréquences (environ > 9 kHz, voir note). Note : Suivant les phénomènes ou équipements considérés, cette fréquence limite peut être déplacée vers une fréquence plus élevée ou plus basse.
General Information
Frequently Asked Questions
IEC/SC 77B is a Subcommittee within the International Organization for Standardization (ISO). It is named "High frequency phenomena" and is responsible for: Standardization in the field of electromagnetic compatibility with regard to high frequency continuous and transient phenomena (ca > 9 kHz, see Note). Note: This limit frequency can be adapted toward a lower or higher frequency according to the phenomena or equipment. This committee has published 62 standards.
IEC/SC 77B develops ISO standards in the area of Information technology. The scope of work includes: Standardization in the field of electromagnetic compatibility with regard to high frequency continuous and transient phenomena (ca > 9 kHz, see Note). Note: This limit frequency can be adapted toward a lower or higher frequency according to the phenomena or equipment. Currently, there are 62 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.
