This part of IEC 61810 applies to electromechanical elementary relays (non-specified time allor- nothing relays) for incorporation into low voltage equipment (circuits up to 1 000 V alternate current or 1 500 V direct current). It defines the basic functional and safety requirements and safety-related aspects for applications in all areas of electrical engineering or electronics@ such as: general industrial equipment@ electrical facilities@ electrical machines@ electrical appliances for household and similar use@ information technology and business equipment@ building automation equipment@ automation equipment@ electrical installation equipment@ medical equipment@ control equipment@ telecommunications@ vehicles@ transportation (e.g. railways) Compliance with the requirements of this standard is verified by the type tests indicated. In case the application of a relay determines additional requirements exceeding those specified in this standard@ the relay should be assessed in line with this application in accordance with the relevant IEC standard(s) (e.g. IEC 60730-1@ IEC 60335-1@ IEC 60950-1).
