La CEI 60364-5-56:2009 traite des exigences générales relatives aux services de sécurité, au choix et à la mise en oeuvre des alimentations électriques des installations et des sources de sécurité. Les alimentations électriques de remplacement ne sont pas traitées dans la présente partie. Cette partie ne s'applique pas aux installations dans les zones à risque d'explosion (BE3) pour lesquelles des exigences sont données dans la CEI 60079-14. Cette deuxième édition de la CEI 60364-5-56 est issue de la révision de l'Article 556, Installations de sécurité, de la CEI 60364-5-55 (2001), telle que modifiée par son amendement 1 (2001). Elle remplace l'Article 556

This European Standard specifies methods of measurement of electrical power consumption, and the reporting of results, for external power supplies. This standard is applicable to external power supplies with a rated input voltage within the range 100 V ac to 250 V ac having a single output with a rated output power not exceeding 250 W and a rated output voltage not exceeding 230 V a.c. or 325 V d.c. The output voltage may be either at a fixed voltage, or at a voltage which is user selectable, or at a voltage that is automatically selectable by the external power supply so as to be compatible with one or more product-loads.
