IEC 61810-2-1:2017 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 IEC 62061 and ISO 13849-1. For such relays, <em>B</em><sub>10</sub> values for dangerous failures (<em>B</em><sub>10D</sub> 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.
