In order to verify whether a fan is compliant with the mandatory provisions we have to consider Table 10.8B, haven't we?
That table is relative to an electricity frequency equal to 60Hz. Since in Europe the fans are tested with 50Hz, how can we evaluate the efficiency with 60Hz?

That particular mandatory provision is not evaluated in LEED Reviews. You should be fine complying with any local or EU standards.

Motor with 50 Hz is exempted as per ASHRAE User Manual.
Mandatory requirements mentioned in the standard under different sections (5.4,6.4,10.4) seems more flexible with US/Canada Locations. Projects in Europe, middle east, Asia regions find it difficult to meet those mandatory requirements.

Thank you.
Which part of the ASHRAE User Manual exempts motors with 50 Hz?
