Anotation

IEC 60393-4:2023 is applicable to single-turn rotary power potentiometers wire-wound technology. Enamelled, cemented, moulded, enclosed. This specification is applicable to rotary potentiometers with nominal dissipation in excess of 10 W, the resistive element of which consists of a wire or a wound tape. All the potentiometers specified by this specification are slider-driven without reduction. Their stroke less than 360° is limited by stops. This document specifies preferred ratings and characteristics and selects from IEC 60393-1, appropriate quality assessment procedures, tests and measuring methods. It provides general performance requirements for this type of potentiometer. This document gives the minimum performance requirements and test severities. Annex A lists the letters and symbols used in the clauses of this document. This edition includes the following significant technical changes with respect to the previous edition: a) the document structure has been organized to follow new sectional specification structure decided in TC 40; b) the information on the assessment level EZ and FZ (zero nonconforming) has been revised. L’IEC 60393-4:2023 s’applique a la technologie bobinee des potentiometres rotatifs monotours a forte dissipation (potentiometres emailles, cementes, moules ou sous enveloppe). La presente specification s’applique aux potentiometres rotatifs de dissipation nominale superieure a 10 W, dont l’element resistif est constitue d’un fil ou d’une bande enroulee. Tous les potentiometres specifies par la presente specification sont entraines par coulisseau sans reduction. Leur course inferieure a 360° est limitee par des butees. Le present document specifie des valeurs assignees et des caracteristiques preferentielles et choisit, a partir de l’IEC 60393-1, des procedures d’assurance de la qualite, des essais et des methodes de mesure appropries. Il donne des exigences generales de performance pour ce type de potentiometre. Le present document fixe les exigences minimales de performance et les severites des essais. L’Annexe A liste les lettres et symboles utilises dans les articles du present document. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: a) l’organisation de la structure du document suit la nouvelle structure de specification intermediaire decidee au sein du TC 40; b) les informations sur le niveau d’evaluation EZ et FZ (zero non conforme) ont ete revisees.
