scope:

This part of IEC 61810 applies to electromechanical elementary relays (non-specified time all-or-nothing relays) for incorporation into low voltage equipment (circuits up to 1000 V alternate current or 1500 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:

1. • general industrial equipment,
2. • electrical facilities,
3. • electrical machines,
4. • electrical appliances for household and similar use,
5. • information technology and business equipment,
6. • building automation equipment,
7. • automation equipment,
8. • electrical installation equipment,
9. • medical equipment,
10. • control equipment,
11. • telecommunications,
12. • vehicles,
13. • 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).
