Electromechanical elementary relays. Reliability. Procedure for the verification of B10 values | Status: Superseded, Withdrawn

1 Scope 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 B10 values for dangerous failures (B10d values) are derived from the tests specified in this standard. This International Standard is only intended to be used in conjunction with IEC 61810‑2.
