IEC 60050-192:2015 gives the general terminology used in the field of dependability. The terms are generic and are applicable to all fields of dependability methodology, including electrotechnical applications. The document is not an exhaustive vocabulary for all IEC standards in the dependability field: definitions for some specialized terms may only be found in the relevant standards. This document replaces sections 1 to 20 of IEC 60050-191:1990, which has been subjected to a systematic, in-depth review and revision, in order to reflect the current usage of the terms in the dependability field, to introduce new terms from new or revised standards, and other informed sources, and to provide a grammatical form, and presentation to comply with the IEC directives. It has the status of a horizontal standard in accordance with IEC Guide 108 . This terminology is consistent with the terminology developed in the other specialized parts of the IEV.
