This part of IEC 61810<\/span> <\/span> specifies reliability test procedures for electromechanical elementary relays when enhanced requirements for the verification of reliability apply.<\/p>\n

Particular provisions are given for relays incorporated in safety-related control systems of machinery in accordance with IEC 62061<\/span> <\/span> and ISO 13849\u20111<\/span> <\/span>. For such relays, B<\/i> 10<\/sub> values for dangerous failures ( B<\/i> 10D<\/sub> values) are derived from the tests specified in this document.<\/p>\n
