IEC/SC 37A - Low-voltage surge protective devices
To prepare international standards for surge protective devices (SPDs) for protection against indirect and direct effects of lightning and/or against other transient overvoltages and for information on their selection and application. These devices are to be used in power, telecommunications and/or signalling networks with voltages up to 1000 V a.c. and 1500 V d.c. Requirements for selection and erection of SPDs in electrical installations of buildings as covered by TC 64 are excluded.
Dispositifs de protection basse tension contre les surtensions
Préparer les normes internationales des parafoudres pour la protection contre les effets directs ou indirects de la foudre et/ou contre d'autres surtensions transitoires et pour l'information sur leur choix et leurs applications. Ces dispositifs sont à utiliser dans les réseaux de distribution de puissance, de télécommunication et/ou de signalisation ayant des tensions allant jusqu'à 1 000 V alternatifs et 1 500 V continus. Les prescriptions pour le choix et le montage des parafoudres dans les installations électriques des bâtiments dépendant du TC 64 sont exclues.

IEC/SC 37A develops ISO standards in the area of Information technology. The scope of work includes: To prepare international standards for surge protective devices (SPDs) for protection against indirect and direct effects of lightning and/or against other transient overvoltages and for information on their selection and application. These devices are to be used in power, telecommunications and/or signalling networks with voltages up to 1000 V a.c. and 1500 V d.c. Requirements for selection and erection of SPDs in electrical installations of buildings as covered by TC 64 are excluded. Currently, there are 19 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.
