c) The terms and definitions of characteristic stimulus quantities have been deleted (see 447-03-03 of the:2009 edition):

This document is equivalent to IEC 60050-447:2020 "International Electrotechnical Vocabulary Part 447: Measuring relays and protection devices":

The following minimal editorial changes were made to this document:

--- For ease of use, the standard name is changed to "Electrical Terminology Measuring Relays and Protection Equipment";

---To keep the document concise, Figures 1 to 4 appear only when they are cited for the first time and do not appear repeatedly:
