431.135—Units to be tested.

For each basic model of automatic commercial ice maker selected for testing, a sample of sufficient size shall be selected at random and tested to ensure that—
(a) Any represented value of estimated maximum energy use or other measure of energy consumption of a basic model for which consumers would favor lower values shall be no less than the higher of:
(1) The mean of the sample, or
(2) The upper 95 percent confidence limit of the true mean divided by 1.10; and
(b) Any represented value of the energy efficiency or other measure of energy consumption of a basic model for which consumers would favor higher values shall be no greater than the lower of:
(1) The mean of the sample, or
(2) The lower 95 percent confidence limit of the true mean divided by 0.90.
(Components of similar design may be substituted without requiring additional testing if the represented measures of energy continue to satisfy the applicable sampling provision.)
