(a) Determination of represented value. Manufacturers must determine the represented value, which includes the certified rating, for each basic model of general purpose pump either by testing (which includes the calculation-based methods in the test procedure), in conjunction with the following sampling provisions, or by application of an AEDM that meets the requirements of § 429.70 and the provisions of this section. Manufacturers must determine the represented value, which includes the certified rating, for each basic model of dedicated-purpose pool pump by testing, in conjunction with the following sampling provisions. Manufacturers must update represented values to account for any change in the applicable motor standards in subpart B of part 431 of this chapter and certify amended values as of the next annual certification.

(A) The mean of the sample,

where: and x is the sample mean, n is the number of samples, and xi is the maximum of the ith sample;

Or,

(B) The upper 95 percent confidence limit (UCL) of the true mean divided by 1.05,

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 percent one-tailed confidence interval with n-1 degrees of freedom (from appendix A of subpart B of part 429).

(ii) Any representation of weighted energy factor of a basic model must be 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 maximum of the ith sample; or,

(B) The lower 95 percent confidence limit (LCL) of the true mean divided by 0.95, where:

(viii) Other reported values. The representative value of any other reported value of a basic model of circulator pump must be determined based on the mean of that value for each tested unit.

(3) Alternative efficiency determination methods. In lieu of testing, a represented value of efficiency or consumption for a basic model of pump must be determined through the application of an AEDM pursuant to the requirements of § 429.70 and the provisions of this section, where:

(i) Any represented value of energy consumption or other measure of energy use of a basic model for which consumers would favor lower values shall be greater than or equal to the output of the AEDM and less than or equal to the Federal standard for that basic model; and

(ii) Any represented value of energy efficiency or other measure of energy consumption of a basic model for which consumers would favor higher values shall be less than or equal to the output of the AEDM and greater than or equal to the Federal standard for that basic model.
