| Table 6.8.1-21 Ceiling Fan | Efficiency Requirements a | Col3 | Col4 |
|---|---|---|---|
| Equipment Type | Size Category | Minimum Efficiencyb | Test Procedurec |
| Large-diameter ceiling fan for applications outside the U.S. | Blade span ≥ 84.5 in. | CFEI ≥ 1.00 at high (maximum) speed; and CFEI ≥ 1.31 at 40% of high speed or the nearest speed that is not less than 40% of high speed | 10 CFR 430 Appendix U or AMCA Standard 230 and AMCA Standard 208 |
a. The minimum efficiency requirements at both high speed and 40% of maximum speed must be met or exceeded to comply with this standard. b. Ceiling fans are regulated in the U.S. as consumer products under 10 CFR 430. For U.S. applications of large-diameter ceiling fans, refer to Informative Appendix F, Table F-6,
for the U.S. DOE minimum efficiency requirements. c. Section 13 contains a complete specification of the referenced test procedure, including the referenced year version of the test procedure.
