TS EN ISO 13349-1

TS EN ISO 13349-1 is a vocabulary standard for fans, defining the terms and category names used in this technical field. It provides a common language for fan technology so that the same word is not used inconsistently for different equipment; in particular, it frames the naming of core concepts such as air movement, flow rate, pressure rise, and fan types. The document does not address electrical safety; its focus is terminology and category definitions.

Why fan terminology needs a dedicated vocabulary

Fans are machines that move air or other gases and are used in ventilation, air conditioning, industrial processes, and cooling systems. Although the underlying physical principle is shared, axial, centrifugal, and mixed-flow fans differ in geometry, performance behaviour, installation arrangement, and typical use. The value of this standard is that it reduces ambiguity in technical documentation, catalogues, engineering communication, and classification work by defining these differences with consistent terms.

What the scope means in practice

• It standardises terminology and category definitions.
• It helps distinguish conceptually between fan types.
• It supports a common language in technical writing and product documentation.
• It addresses naming and classification, not electrical safety requirements.

In general technical context, fan performance depends not only on rotational speed but also on impeller geometry, casing arrangement, operating point, and the pressure difference created across the system. For that reason, accurate terminology is more than naming convention: it is a practical tool for comparison and correct selection. TS EN ISO 13349-1 establishes that shared language and forms a foundation for more detailed standards, tests, and product documentation relating to fans.
