94 - All-or-nothing electrical relays

IEC 61810-10:2019, with functional and safety aspects, applies to electromechanical elementary relays (non-specified time all-or-nothing relays) with high capability requirements like breaking or short circuit capabilities and similar for incorporation into low-voltage equipment. These relays may have a specific design to extinguish the electric arc between contacts (e.g. by magnetic blow-out), or use an insulation coordination not covered by IEC 61810-1 (e.g. by gas filled contact chambers), or...view more

IEC 61810-2:2017 covers test conditions and provisions for the evaluation of endurance tests using appropriate statistical methods to obtain reliability characteristics for relays.
This document applies to electromechanical elementary relays considered as non-repaired items (i.e. items which are not repaired after failure).
This document does not cover procedures for electromechanical elementary relays where enhanced requirements for the verification of reliability apply.
This edition include...view more

IEC 61810-2-1:2017 specifies reliability test procedures for electromechanical elementary relays when enhanced requirements for the verification of reliability apply.
Particular provisions are given for relays incorporated in safety-related control systems of machinery in accordance with IEC 62061 and ISO 13849-1. For such relays, B10 values for dangerous failures (B10D values) are derived from the tests specified in this document.
This edition includes the following significant technical chan...view more

IEC 61810-3:2015 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.

IEC 61810-1:2015 applies to electromechanical elementary relays (non-specified time all-or-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 ...view more

IEC 61811-1:2015 applies to electromechanical telecom elementary relays. Relays according to this standard are provided for the operation in telecommunication applications. However, as electromechanical elementary relays, they are also suitable for particular industrial and other applications. This standard selects from IEC 61810 series and other sources the appropriate methods of test to be used in detail specifications derived from this specification, and contains basic test schedules to be us...view more

IEC 62246-1:2015, which is a generic specification, applies to all types of reed switches including magnetically biased reed switches of assessed quality for use in general and industrial applications. Mercury wetted reed switches are not covered by this standard due to their possible environmental impact. It lists the tests and measurement procedures which may be selected for use in detail specifications for such reed switches. This standard applies to reed switches which are operated by an app...view more

IEC 61812-1:2011 applies to time relays for industrial applications (e.g. control, automation, signal and industrial equipment). It also applies to time relays for automatic electrical controls for use in, on, or in association with equipment for residential and similar use. This edition includes the following significant technical changes with respect to the previous edition:
- addition of terms and definitions more commonly used by industry;
- addition of timing charts to help explain terms ...view more

States the characteristics of solid-state relays; the requirements with respect to their operation and behaviour; their dielectric properties; the degrees of protection provided by their enclosures; the tests verifying that the requirements have been met, and the test methods to be adopted.

IEC 61810-7:2006 Lays down the test and measurement procedures for electromechanical elementary relays. Covers basic considerations which are common to all types of electromechanical elementary relays. Supplementary requirements may be necessitated by specific designs or application.
