Electromechanical elementary relays - Part 2: Reliability
IEC 61810-2:2011 covers test conditions and provisions for the evaluation of endurance tests using appropriate statistical methods to obtain reliability characteristics for relays. The main changes with respect to the previous edition are listed below: inclusion of both numerical and graphical methods for Weibull evaluation; establishment of full coherence with the second edition of the basic reliability standard IEC 61649.
This publication is to be read in conjunction with IEC 61649:2008.

Relais électromécaniques élémentaires - Partie 2: Fiabilité
La CEI 61810-2:2011 couvre les conditions d'essai et les dispositions pour l'évaluation des essais d'endurance utilisant les méthodes statistiques appropriées pour obtenir les caractéristiques de fiabilité pour relais. Les principales modifications portant sur cette précédente édition sont énumérées ci-dessous: inclusion de méthodes numériques et graphiques pour l'évaluation de Weibull; établissement d'une cohérence complète avec la deuxième édition de la norme de fiabilité de base CEI 61649.
Cette publication doit être lue conjointement avec la CEI 61649:2008.
Osnovni elektromehanski releji - 2. del: Zanesljivost
Ta del IEC 61810 zajema preskusne pogoje in določbe za vrednotenje preskusov vzdržljivosti z uporabo ustreznih statističnih metod za pridobivanje značilnosti zanesljivosti relejev. Uporabljal naj bi se skupaj z IEC 61649.
Ta mednarodni standard velja za osnovne elektromehanske releje, ki veljajo za nepopravljive predmete (tj. predmete, ki se po okvari ne popravljajo), kadar koli se naključni vzorec predmetov preskuša s številom ciklov do okvare (CTF).
Življenjska doba releja se po navadi izraža v številu ciklov. Kadar se v IEC 61649 uporabljata izraza »čas« in »trajanje«, zato pomenita »cikli«. Z dano frekvenco obratovanja pa se število ciklov lahko pretvori v ustrezen čas (npr. čas do okvare (TTF)).
V tem standardu so določena merila za okvaro in nastale značilnosti osnovnih relejev, ki opisujejo njihovo zanesljivost pri normalni uporabi. Do okvare releja pride, kadar so izpolnjena opredeljena merila za okvaro.
Ker stopnja okvare za osnovne releje ne velja za konstantno, še zlasti zaradi mehanizmov izrabe, so časi do okvare preskušanih predmetov praviloma porazdeljeni po Weibullu. Ta standard podaja številčne in grafične metode za izračun približnih vrednosti dvoparametrične Weibullove porazdelitve in spodnje meje zaupanja.

Foreword
The text of document 94/316/FDIS, future edition 2 of IEC 61810-2, prepared by IEC TC 94,
All-or-nothing electrical relays, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 61810-2 on 2011-04-01.
This European Standard supersedes EN 61810-2:2005.
The main changes with respect to EN 61810-2:2005 are listed below:
— inclusion of both numerical and graphical methods for Weibull evaluation;
— establishment of full coherence with the second edition of the basic reliability standard EN 61649;
— deletion of previous Annex A and Annex D since both annexes are contained in EN 61810-1.
This standard is to be used in conjunction with EN 61649:2008.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2012-01-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-04-01
Annex ZA has been added by CENELEC.
