This part of IEC 61810 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, B 10 values for dangerous failures ( B 10D values) are derived from the tests specified in this document.
