Title Electromechanical elementary relays - Part 2: Reliability
Project Number 22688
Abstract/Scope 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.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
