scope:

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).
