About This Item
TS IEC 60050-191+A1+A2 is a vocabulary standard for Chapter 191 of the International Electrotechnical Vocabulary, combining the base edition with Amendments A1 and A2. It brings together terms and definitions for dependability and quality of service, helping technical users apply a common language to concepts such as reliability, availability, failure behavior, and service performance.
How the technical vocabulary is organised
In general technical usage, dependability and quality of service are concerned not only with whether a system functions, but with how consistently it performs its intended role over time. The subject covers concepts such as failure, maintenance, interruption, recoverability, continuity, and the quality of service delivered to users. This chapter standardises that terminology so engineering, operations, and documentation teams can communicate with less ambiguity.
What this document provides
- Terms and definitions related to dependability and quality of service
- A combined listing of IEC 60050-191 with Amendments A1 and A2
- A reference vocabulary for electrical and electrotechnical contexts
- Terminology support for consistent interpretation across technical disciplines
This is not a test method standard or a document that directly measures product performance; its value lies in defining concepts precisely and consistently. As a result, it supports reliability engineering, maintenance planning, service continuity work, and the drafting of technical specifications where wording must remain clear and unambiguous.
