According to Commission Regulation (EU) No 327/2011 implementing Directive 2009/125/EC.
**
The stagnation pressure measured at the fan outlet divided by the stagnation pressure at the fan inlet at the optimal energy effi-
ciency point of the fan.
*** Additional items used when determining the fan energy efficiency that is not described in the measurement category and not supplied
with the fan.
