(a) Sampling plan for selection of units for testing.

(1) The requirements of §429.11 are applicable to room air conditioners; and

(2) For each basic model of room air conditioners, a sample of sufficient size shall be randomly selected and tested to ensure that—

(i) Any represented value of estimated annual operating cost, energy consumption or other measure of energy consumption of a basic model for which consumers would favor lower values shall be greater than or equal to the higher of:

(A) The mean of the sample, where:

or,

(B) The upper 971⁄2 percent confidence limit (UCL) of the true mean divided by 1.05, where:

and

(ii) Any represented value of the energy efficiency ratio 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 lower of:

(A) The mean of the sample, where:

or,

(B) The lower 971⁄2 percent confidence limit (LCL) of the true mean divided by 0.95, where:

(b) Certification reports.

(1) The requirements of §429.12 are applicable to room air conditioners; and

(2) Pursuant to §429.12(b)(13), a certification report shall include the following public product-specific information: The energy efficiency ratio (EER in British thermal units per Watt-hour (Btu/W-h)), cooling capacity in British thermal units per hour (Btu/h), and the electrical power input in watts (W).
