TS ISO 10110-11

TS ISO 10110-11 is Part 11 of the drawing-preparation series for optical elements and optical systems, focused on data that are presented without tolerances. In practical terms, it addresses how information on an optical drawing may be identified when it is not intended to define a dimensional limit or acceptance band. This edition has been withdrawn, but the subject remains useful for understanding the disciplined language used in optical engineering documentation.

What non-toleranced data means in optical documentation

In general technical usage, a tolerance defines the permissible variation of a characteristic. On optical drawings, however, not every piece of information needs to carry a numerical tolerance. Some items are descriptive, reference-based, or explanatory rather than directly controlling manufacture. The concept of non-toleranced data is about keeping those items distinct from controlled requirements so they are not mistaken for acceptance criteria. That distinction matters because small wording differences can affect how an optical surface, alignment feature, or assembly condition is produced and inspected.

Why this part matters in the ISO 10110 drawing system

The ISO 10110 series establishes a common documentation language for optical components and systems. Within that framework, non-toleranced data help separate design intent, auxiliary notes, and supportive information from mandatory manufacturing conditions. This improves drawing clarity and reduces ambiguity between what is meant as a requirement and what is included for information only. In lenses, mirrors, and more complex optical subassemblies, that separation is especially valuable for communication between design, manufacturing, and quality control teams.
