The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61812-1:2023 applies to time relays and coupling relays for industrial applications (for example control, automation, signal and industrial equipment) and for automatic electrical controls for use in, on, or in association with equipment for residential and similar use. The term “relay” as used in this document comprises all types of time relays and coupling relays, other than measuring relays. This document defines type test and routine test to confirm the service condition. Subclause 3.2 provides definitions for different types of time relays in use in the IEC 61812 series. IEC 61812-1:2023 cancels and replaces the second edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) update of references; b) addition of requirements for risk assessment; c) addition of requirements for routine test; d) renumbering of clauses to bring them into a more logical order; e) clarification of the requirement for shock; f) addition of cybersecurity requirements for industrial automation and control systems; g) addition of environmentally conscious design requirement; h) addition of common data dictionary reference; i) addition of terms and definitions of relay types; j) addition of coupling relays in title; k) addition of coupling relays in scope.
