PART 429CERTIFICATION, COMPLIANCE, AND ENFORCEMENT
FOR CONSUMER PRODUCTS AND
COMMERCIAL AND INDUSTRIAL
EQUIPMENT

For the reasons stated in the preamble, DOE proposes to amend parts 429 and 430 of chapter II of title 10, Code of Federal Regulations as set forth below:

And x is the sample mean; s is the sample standard deviation; n is the number of samples; and t0.95 is the t statistic for a 95% one-tailed confidence interval with n-1 degrees of freedom from appendix A
to this subpart; and 3 For each basic model of ceiling fan, i Any represented value of blade span, as defined in section 1.4 of appendix U to subpart B of part 430, is the mean of the blade spans measured for the sample selected as described in paragraph a1 of this section, rounded to the nearest inch; and ii Any represented value of blade revolutions per minute RPM is the mean of the blade RPM measurements measured for the sample selected as described in paragraph a1 of this section, rounded to the nearest RPM; and
iii Any represented value of blade edge thickness is the mean of the blade edge thicknesses measured for the sample selected as described in paragraph a1 of this section, rounded to the nearest 0.01 inch; and iv Any represented value of the distance between the ceiling and the lowest point on the fan blades is the mean of the distances measured for the sample selected as described in paragraph a1 of this section, rounded to the nearest quarter of an inch;
and v Any represented value of tip speed is pi multiplied by represented value of blade span divided by twelve multiplied by the represented value of RPM, rounded to the nearest foot per minute;
vi Any represented value of airflow CFM at high speed, including the value

used to determine whether a ceiling fan is a highly-decorative ceiling fan as defined in section 1.9 of appendix U to subpart B of part 430, is determined pursuant to paragraph a2i and rounded to the nearest CFM; and 4 To determine values required by the Federal Trade Commission FTC, use the following provisions. Note that, for multimount ceiling fans these values must be reported on the EnergyGuide label for the ceiling fan configuration with the lowest efficiency.

i FTC Airflow. Determine the represented value for FTC airflow by calculating the weighted-average airflow of an LSSD or VSD ceiling fan basic model at low and high fan speed as follows:
