Définition des terms

Type of publication

horizontal safety function
Task assigned to a TC to prepare one or more basic safety publications


basic safety publication
Publication on a specific safety-related matter, applicable to many electrotechnical products

group safety function

A propos des Fonctions de Sécurité

The assignment of horizontal safety functions and group safety functions is the responsibility of the Advisory Committee on Safety (ACOS), subject to confirmation by the Standardization Management Board (SMB).

Information on the preparation and use of basic safety publications and group safety publications can be found in
IEC Guide 104.

This guide should be used in conjunction with
ISO/ IEC Guide 51.

Fonctions Horizontales de Sécurité

Fonction Horizontal de Sécurité
Sécurité de Base

Installations électriques et protection contre les chocs électriques

Protection against electric shock
(See also Group Safety Functions)

Aspects systèmes

Functional safety of electrical/ electronic/ programmable electronic systems, (which would encompass safety-related software).

Degrés de protection procurés par les enveloppes

Degrees of protection provided by enclosures against ingress of foreign bodies, water and access to live or moving parts and standardization of accessibility probes. Such degrees should be expressed by the IP classification system.

Compatibilité électromagnétique

Electromagnetic compatibility in so far as safety aspects are involved.

Essais relatifs aux risques du feu

Guidance and test methods for assessing fire hazards of electrotechnical equipment, their parts (including components) and electrical insulating materials. Note: Terms and definitions in the field of fire tests from ISO/IEC 13943 are used wherever appropriate.


To specify methods of test and relevant equipment to evaluate generation, retention and dissipation of electrostatic charges on materials.

Conditions, classification et essais d'environnement

Methods for climatic tests
Methods for testing mechanical robustness

Sécurité des appareils électroniques dans le domaine de l'audio, de la vidéo, du traitement de l'information et des technologies de la communication

Methods of measuring touch current and protective conductor current. This includes methods of measurement of touch current with regard to physiological effects and of protective conductor current for installation purposes. The methods of measurement consider both normal conditions and certain fault conditions.
Safety of equipment - electrically connected to a telecommunications network.
