Scope

AS/NZS ISO 12759.4:2023 identically adopts ISO 12759 4:2019, which establishes a system for the classification of fan efficiency for all fan types driven by motors of nominal rating 0.125 kW and above. It applies to driven fans only, but not to the system in which they might be installed. This document describes a number of different procedures to classify the efficiency of a fan or to apply a minimum efficiency limit (MEL)
