TS EN ISO 10991

TS EN ISO 10991 is a vocabulary standard for micro process engineering. Documents of this kind give a common technical language to engineers, researchers, manufacturers, and laboratory users working with microscale flow and process systems, where precise wording matters because many terms are closely related and often used across different disciplines.

Why terminology matters in micro process engineering

Micro process engineering generally deals with very small channels, microstructured devices, and process conditions that exploit high surface-to-volume ratios to improve control over reaction, mixing, and heat transfer. In that setting, terms such as microreactor, micromixer, microchannel, and continuous-flow concepts need consistent definitions so that publications, specifications, and training materials describe the same idea in the same way.

What this document type is used for

• It brings together terminology used in micro process engineering in a shared vocabulary framework.
• It supports consistent communication in technical documentation, teaching, and research.
• It helps reduce ambiguity between closely related terms used in chemistry and process engineering contexts.
• As a vocabulary standard, its focus is definitional clarity rather than design rules or performance limits.

This record represents a withdrawn edition, so it should be treated as a historical reference for terminology in the field rather than the current authority. Even so, it remains useful for understanding the conceptual structure of micro process engineering and the relationships between the main terms used in the discipline.

TS EN ISO 10991 should therefore be understood as a reference vocabulary for the field, helping users align terminology around the core concepts of microscale process technology rather than prescribing how equipment must be designed.
