TS ISO/IEC 2382-14

TS ISO/IEC 2382-14 is the vocabulary part of the information technology series devoted to reliability, maintainability, and availability. It brings together selected terms and definitions for concepts used in information processing and shows relationships among the entries, with the aim of supporting consistent international communication. In practical technical use, it helps distinguish ideas such as how dependable a system is, how easily it can be maintained, and how readily it is available for use.

Why these terms are kept distinct

In general technical context, reliability refers to the likelihood that an item will perform its intended function under stated conditions. Maintainability concerns how effectively a system can be serviced, repaired, and kept in operation. Availability describes the degree to which a system is in a usable state when required. These are related but not interchangeable concepts, and vocabulary standards are valuable precisely because they separate such terms clearly for engineering, quality, and documentation purposes.

Terminology support for international communication

This part of the ISO/IEC 2382 vocabulary series is written to avoid language-specific peculiarities as far as possible, making the definitions easier to translate and apply across languages. For organizations working with information systems, the value lies in shared terminology rather than in test procedures or numerical performance limits. The listing is marked as a withdrawn standard, so it should be understood as a historical terminology reference within the TSE catalogue rather than a current normative requirement set.
