Federal Register / Vol. 86, No. 232 / Tuesday, December 7, 2021 / Proposed Rules Where:
EYECFTC = represented value for FTC
estimated yearly energy cost, rounded to the nearest dollar, and WLow = represented value of measured power consumption, in watts, at low fan speed, pursuant to paragraph a2ii of this section, WHigh = represented value of measured power consumption, in watts, at high fan speed, pursuant to paragraph a2ii of this section, and Wsb = represented value of measured power consumption, in watts, in standby mode, pursuant to paragraph a2ii of this section.

3. Section 429.134 is amended by adding paragraph s to read as follows:

s Ceiling Fans1 Verification of blade span. DOE will measure the blade span and round the measurement pursuant to the test requirements of 10
CFR part 430 of this chapter for each unit tested. DOE will consider the represented blade span valid only if the rounded measurements either the rounded measured value for a single unit, or the mean of the rounded measured values for a multiple unit sample, rounded to the nearest inch is the same as the represented blade span.
i If DOE determines that the represented blade span is valid, that blade span will be used as the basis for determining the product class and calculating the minimum allowable ceiling fan efficiency.
ii If DOE determines that the represented blade span is invalid, DOE
will use the rounded measured blade spans as the basis for determining the product class, and calculating the minimum allowable ceiling fan efficiency.
2 Verification of the distance between the ceiling and lowest point of fan blades. DOE will measure the distance between the ceiling and lowest point of the fan blades and round the measurement pursuant to the test requirements of 10 CFR part 430 of this chapter for each unit tested. DOE will consider the represented distance valid only if the rounded measurements either the measured value for a single unit, or the mean of the measured values for a multiple unit sample, rounded to the nearest quarter inch are the same as the represented distance.
i If DOE determines that the represented distance is valid, that distance will be used as the basis for determining the product class.
ii If DOE determines that the represented distance is invalid, DOE

will use the rounded measured distances as the basis for determining the product class.
3 Verification of blade revolutions per minute RPM measured at high speed. DOE will measure the blade RPM
at high speed pursuant to the test requirements of 10 CFR part 430 of this chapter for each unit tested. DOE will consider the represented blade RPM
measured at high speed valid only if the measurements either the measured value for a single unit, or the mean of the measured values for a multiple unit sample, rounded to the nearest RPM are within the greater of 2% of the represented blade RPM at high speed.
i If DOE determines that the represented RPM is valid, that RPM will be used as the basis for determining the product class.
ii If DOE determines that the represented RPM is invalid, DOE will use the rounded measured RPMs as the basis for determining the product class.
4 Verification of blade edge thickness. DOE will measure the blade edge thickness and round the measurement pursuant to the test requirements of 10 CFR part 430 for each unit tested. DOE will consider the represented blade edge thickness valid only if the measurements either the measured value for a single unit, or the mean of the measured values for a multiple unit sample, rounded to the nearest 0.01 inch are the same as the represented blade edge thickness.
i If DOE determines that the represented blade edge thickness is valid, that blade edge thickness will be used for determining product class.
ii If DOE determines that the represented blade edge thickness is invalid, DOE will use the rounded measured blade edge thicknesses as the basis for determining the product class.

1 Circulating Air means the discharge of air in an upward or downward direction with the air returning to the intake side of the fan.
A ceiling fan that has a ratio of fan blade span in inches to maximum rotation rate in revolutions per minute greater than 0.06 provides circulating air.
2 For all other ceiling fan related definitions, see appendix U to this subpart.

6. Section 430.23 is amended by revising paragraph w to read as follows:

PART 430ENERGY CONSERVATION
PROGRAM FOR CONSUMER
PRODUCTS

Appendix U to Subpart B of Part 430
Uniform Test Method for Measuring the Energy Consumption of Ceiling Fans
4. The authority citation for part 430
continues to read as follows:

Prior to effective date of test procedure final rule, manufacturers must make any representations with respect to the energy use or efficiency of ceiling fans as specified in Section 2 of this appendix as it appeared on January 23, 2017. On or after effective date of test procedure final rule, manufacturers of ceiling fans, as specified in section 2 of this appendix, must make any representations with respect to energy use or efficiency in accordance with the results of testing pursuant to this appendix.
Certification of standby power consumption for large-diameter ceiling fans is required from the time that an energy conservation standard on standby power consumption requires compliance.

Authority: 42 U.S.C. 62916309; 28 U.S.C.
2461 note.

5. Section 430.2 is amended by revising the definition of Ceiling fan to read as follows:

430.2
