§ 429.32 Ceiling fans.

(a)Determination of represented value. Manufacturers must determine the represented value, which includes the certified rating, for each basic model of ceiling fan by testing, in conjunction with the following sampling provisions:

(1) The requirements of § 429.11 are applicable to ceiling fans; and

(2) For each basic model of ceiling fan selected for testing, a sample of sufficient size must be randomly selected and tested to ensure that -

(i) Any represented value of the efficiency or airflow is less than or equal to the lower of:

(A) The mean of the sample, where:

And x is the sample mean; n is the number of samples; and xi is the ith sample; or

(B) The lower 90 percent confidence limit (LCL) of the true mean divided by 0.9, where:

And x is the sample mean; s is the sample standard deviation; n is the number of samples; and t0.90 is the t statistic for a 90% one-tailed confidence interval with n−1 degrees of freedom (from appendix A to subpart B); and

(ii) Any represented value of the wattage is greater than or equal to the higher of:

(A) The mean of the sample, where:

And x is the sample mean; n is the number of samples; and xi is the ith sample; or

(B) The upper 95 percent confidence limit (UCL) of the true mean divided by 1.1, where:

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).

(b)Certification reports.

(1) The requirements of § 429.12 are applicable to ceiling fans; and

(2) Pursuant to § 429.12(b)(13), a certification report shall include the following public product-specific information: The number of speeds within the ceiling fan controls and a declaration that the manufacturer has incorporated the applicable design requirements.
