BSI | 2015 | 18 |
This part of IEC 61810 specifies special requirements and tests for elementary relays with forcibly guided contacts, also known as mechanically linked contacts. These special requirements apply in addition to the general requirements of IEC 61810‑1 .
This standard does not apply to electromechanical control circuit devices as described in IEC 60947‑5‑1.
IEC 61810‑2‑1 provides guidelines for the assignment of reliability values.
Contacts that are not mechanically linked (forcibly guided) are not considered in this standard.
