    Abstract - (Show below) - (Hide below)

    IEC61810-2-1:2017 specifies reliability test procedures for electromechanical elementary relays when enhanced requirements for the verification of reliability apply.Particular provisions are given for relays incorporated in safety-related control systems of machinery in accordance with IEC62061 and ISO13849-1. For such relays, B10 values for dangerous failures (B10D values) are derived from the tests specified in this document.This edition includes the following significant technical changes with respect to the previous edition:- limitation of tests to 10 M cycles in Clause 5;- reduction of required number of test samples to 5 in specified cases;- introduction of WeiBayes analysis for routine test under Clause 4.
