Electromechanical telecom elementary relays of assessed quality - Part 1: Generic specification and blank detail specification

IEC 61811-1:2015 applies to electromechanical telecom elementary relays. Relays according to this standard are provided for the operation in telecommunication applications. However, as electromechanical elementary relays, they are also suitable for particular industrial and other applications. This standard selects from IEC 61810 series and other sources the appropriate methods of test to be used in detail specifications derived from this specification, and contains basic test schedules to be used in the preparation of such specifications in accordance with this standard. Detailed test schedules are contained in the detail specifications. This second edition of IEC 61811-1 cancels and replaces IEC 61811-1 published in 1999, IEC 61811-10 published in 2002, IEC 61811-11 published in 2002, IEC 61811-50 published in 2002, IEC 61811-51 published in 2002, IEC 61811-52 published in 2002, IEC 61811-53 published in 2002, IEC 61811-54 published in 2002, IEC 61811-55 published in 2002, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous editions: a) to get one document for telecom relays; b) update all relevant references.

Elektromechanische Telekom-Elementarrelais mit bewerteter Qualität - Teil 1: Fachgrundspezifikation und Bauartspezifikation

Relais télécom électromécaniques élémentaires soumis au régime d’assurance qualité - Partie 1: Spécification générique et spécification particulière cadre

L'IEC 61811-1:2015 s'applique aux relais télécom électromécaniques élémentaires. Les relais conformes à la présente norme assurent le fonctionnement des applications de télécommunication. Toutefois, comme les relais électromécaniques élémentaires, ils sont également adaptés aux applications industrielles, entre autres. La présente norme sélectionne dans la série IEC 61810 et dans d'autres sources les méthodes d'essai appropriées utilisées dans les spécifications particulières déduites de la présente spécification. Elle contient les programmes d'essai de base à utiliser dans le cadre de la préparation de ces spécifications conformément à la présente norme. Les programmes d'essai détaillés sont contenus dans les spécifications particulières. Cette deuxième édition de l'IEC 61811-1 annule et remplace l'IEC 61811-1 publiée en 1999, l'IEC 61811-10 publiée en 2002, l'IEC 61811-11 publiée en 2002, l'IEC 61811-50 publiée en 2002, l'IEC 61811-51 publiée en 2002, l'IEC 61811-52 publiée en 2002, l'IEC 61811-53 publiée en 2002, l'IEC 61811-54 publiée en 2002, l'IEC 61811-55 publiée en 2002, et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport aux éditions précédentes: a) mise à disposition d'un document concernant les relais télécom; b) mise à jour de toutes les références appropriées.

Elektromehanski telekomunikacijski stikalni releji ocenjene kakovosti - 1. del: Rodovna specifikacija in okvirna podrobna specifikacija

Ta del standarda IEC 61811 se uporablja za elektromehanske telekomunikacijske osnovne releje. Releji v skladu s tem standardom se zagotavljajo za delovanje v okviru telekomunikacijskih uporab. Vendar so kot elektromehanski osnovni releji primerni tudi za posebne industrijske in druge uporabe.
Ta standard izbira med skupino standardov IEC 61810 in drugimi viri ustrezne metode preskušanja, ki se uporabljajo za podrobne specifikacije, ki izhajajo iz te specifikacije, ter zajema osnovne urnike preskusov, ki se uporabljajo pri pripravi takih specifikacij v skladu s tem standardom. Podrobni urniki preskusov so zajeti v podrobnih specifikacijah.
