TS EN ISO 7499

TS EN ISO 7499 is the Turkish listing of the standard that addresses Unique Integral Feature Identification, or UIFI, in technical product documentation (TPD). In practical terms, it is concerned with how individual integral features of a part are identified so that similar details on the same component can be distinguished unambiguously across drawings and related documentation, supporting a common language between design, manufacturing, and inspection.

Unique identification and presentation in TPD

According to the scope, an integral feature is identified by an integral feature indicator together with a unique alpha-numerical label. The document also defines how this identification is shown in TPD where human readability needs to be improved. In general technical use, this kind of convention is valuable because complex parts often contain many similar features, and clear labeling helps preserve traceability and avoids confusion when the documentation is used by different teams.

Simplified symbols for repeated features

The scope also states that the proportions and dimensions of graphical symbols used for a simplified indication of repeated features are specified. More broadly, such rules help keep symbols legible, consistent, and comparable across technical documents. Where repeated holes, surfaces, or other recurring details appear on a part, standardized symbol sizing supports clearer communication and reduces the chance of misreading the intended reference.
