Newly Released IEC 61810-2-1:2017 for Electromechanical Elementary Relays

The International Electrotechnical Commission (IEC) has released IEC 61810-2-1:2017 . This standard pertains to “Electromechanical elementary relays – Part 2-1: Reliability – Procedure for the verification of B₁₀ values,” and is now available on the IEC webstore.

Description: “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, B₁₀ values for dangerous failures (B_10D 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.”
