EN 60523:1993

Direct-current potentiometers

Applicable to d.c. potentiometers assembled from resistors and switches and operating entirely on direct current, having accuracy classes of 0.0005 ... 0.1, as well as to auxiliary equipment which is a built-in part of the potentiometer. Classification system. Permissible errors for each accuracy class. Conditions for determination of errors. Markings. Information by the manufacturer.

Gleichspannungs-Kompensatoren

Potentiomètres à courant continu

S'applique aux potentiomètres à courant continu comportant des résistances et des commutateurs et fonctionnant exclusivement en courant continu, et dont l'indice de classe est 0,0005... 0,1 (5 ppM... 1000 ppM (parties par million)), ainsi qu'aux équipements auxiliaires lorsqu'ils sont incorporés au potentiomètre. Spécifie un système de classification des potentiomètres. Indique les erreurs admissibles pour chaque indice de classe et les conditions pour la détermination des erreurs. Précise les inscriptions nécessaires et les informations à fournir par le constructeur.

1)
The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on which all the National
Committees having a special interest therein are represented, express, as nearly as possible, an inte rn
ational consensus of opinion
on the subjects dealt with.
2) They have the form of recommendations for international use and they are accepted by the National Committees in that sense.
