TC 109 - Insulation co-ordination for low-voltage equipment
To prepare International Standards on the principles of insulation coordination applicable to all low-voltage equipment (up to and including 1 000 V a.c. and 1 500V d.c.). To provide IEC Technical Committees with: - rules for the determination of voltage ratings for insulation coordination, - physical data for dimensioning of insulations to given voltage rating and - guidance for determination of clearances, and creepage distances and requirements for solid insulation with respect to insulation coordination and safety aspects up to 2 000 V a.c and 3 000 V d.c operating voltage. Horizontal Safety Function: Insulation coordination for voltages up to and including 1 000 V a.c. and 1 500 V d.c., including dimensioning of clearances, and creepage distances and requirements for solid insulation with respect to insulation coordination. This includes all methods of dielectric testing with respect to insulation coordination.
Coordination de l'isolement pour le matériel à basse tension
Préparer des normes internationales traitant des principes de coordination de l’isolement applicables à tous les équipements basse tension (inférieure ou égale à 1 000 V en courant alternatif et à 1 500 V en courant continu). Fournir aux Comités d’étude IEC : - des règles pour déterminer les caractéristiques de tension pour la coordination de l’isolement, - des données physiques pour le dimensionnement de l’isolement en fonction d'une caractéristique de tension donnée et - des lignes directrices pour le dimensionnement des distances d’isolement et des lignes de fuite ainsi que des exigences pour l’isolation solide en rapport avec la coordination de l’isolement et les aspects liés à la sécurité pour des tensions de fonctionnement inférieures ou égales à 2 000 V en courant alternatif et à 3 000 V en courant continu. Fonction horizontale de sécurité: Coordination de l'isolement pour des tensions inférieures ou égales à 1 000 V en courant alternatif et à 1 500 V en courant continu, y compris le dimensionnement des distances d’isolement et des lignes de fuite ainsi que des exigences pour l’isolation solide. Ceci comprend toutes les méthodes d'essai des diélectriques en rapport avec la coordination de l'isolement

The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
