IEC/PAS 61810-2-1:2008(E) 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 PAS.
