(a) (1) Units to be tested. The requirements of § 429.11 are applicable to pumps; and for each basic model, a sample of sufficient size shall be randomly selected and tested to ensure that— (i) Any representation of the constant load pump energy index (PEI (A) The mean of the sample, Or, (B) The upper 95 percent confidence limit (UCL) of the true mean divided by 1.05, (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 (B) The lower 95 percent confidence limit (LCL) of the true mean divided by 0.95, where: And x (2) (ii) (iii) (iv) (v) (vi) (vii) (viii) (3) (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. (b) (2) Pursuant to § 429.12(b)(13), a certification report must include the following public product-specific information: (i) For a pump subject to the test methods prescribed in section III of appendix A to subpart Y of part 431 of this chapter: PEI (ii) For a pump subject to the test
