Recommendations in the field of quantities and units used in electricity

IEC 61298-3:2008 specifies general methods and procedures for conducting tests and reporting on the functional and performance characteristics of process measurement and control devices. The tests are applicable to any such devices characterized by their own specific input and output variables, and by the specific relationship (transfer function) between the inputs and outputs, and include analogue and digital devices. For devices that require special tests, this standard should be used, together with any product-specific standard specifying special tests. It covers tests for the effects of influence quantities.

Recommandations dans le domaine des grandeurs et unités utilisées en électricité

La CEI 61298-3:2008 spécifie les méthodes et procédures générales pour l'exécution des essais portant sur les caractéristiques fonctionnelles et les caractéristiques de performance des dispositifs de mesure et de commande de processus. Ces essais sont applicables à tout dispositif à condition que ce dispositif soit caractérisé par ses propres grandeurs d'entrée et de sortie et par la relation spécifique (fonction de transfert) entre les entrées et les sorties. Ils concernent les dispositifs analogiques et numériques. Pour les dispositifs nécessitant des essais spéciaux, il convient que la présente norme soit utilisée en conjonction avec la norme particulière de produit spécifiant ces essais spéciaux. Elle couvre les essais réalisés pour la détermination des effets des grandeurs d'influence.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparat
