TS EN ISO 13349-2

TS EN ISO 13349-2 is a vocabulary standard that organises category names and their definitions for fans, helping technical communication stay consistent. It brings the concept of fan categories into a common framework so that the same term is less likely to be interpreted in different ways across documents, discussions, and product descriptions. The standard applies to fans used for all purposes, but it is not applicable to electrical safety.

How category definitions support fan terminology

Fans are used to move air or other gases, generate pressure, or assist flow within a system. In this field, a category-based approach groups products not only by individual type names but also by broader functional or structural families. In general technical use, this kind of vocabulary standard is about language consistency rather than test methods or performance limits. It helps engineers, manufacturers, and technical authors describe the same equipment in the same way.

Why the distinction matters in practice

Clear category definitions make it easier to distinguish between different fan concepts and to communicate distinctions such as axial, centrifugal, or mixed-flow principles in a disciplined way. The value of TS EN ISO 13349-2 is that it provides a shared terminology basis for design, procurement, documentation, and engineering communication. Because electrical safety is excluded, the document focuses on naming and categorisation rather than safety requirements or protective measures.
