TS EN 13306

TS EN 13306 is a terminology standard for maintenance, bringing together generic terms and definitions used across the technical, administrative, and managerial dimensions of the subject. Its role is to establish a common language for maintenance planning, asset management, performance monitoring, and operational communication, so that the same concepts are understood consistently across organisations and disciplines.

What maintenance terminology is meant to do

Maintenance is broader than repair after failure. In general technical practice, it also includes preventive, corrective, predictive, and improvement-oriented activities that support the intended function of equipment and facilities. A terminology standard helps distinguish these concepts clearly, which is especially important when teams discuss availability, reliability, maintainability, maintenance policy, and related management decisions. For users, the value of EN 13306 is not a set of procedures, but a shared conceptual framework for speaking about maintenance in a precise way.

Defined boundary of the document

The standard is described as covering generic terms and definitions for maintenance in technical, administrative, and managerial areas. It also explicitly states that it is not intended for terms used only in software maintenance. That exclusion matters because software maintenance has its own context and vocabulary, including version handling, defect correction, and updates, which are not identical to the terminology used for physical assets and industrial equipment. In that sense, TS EN 13306 functions as a core reference for maintenance language and professional communication.
