Sampling Plan for Enforcement Testing of Uninterruptible Power Supplies

(a) The minimum sample size for enforcement testing will be one unit. (b) Compute the average load adjusted efficiency ( Eff avg ) of the unit in the sample. (c) Determine the applicable DOE energy efficiency standard (EES). (d) If all Eff avg are equal to or greater than EES, then the basic model is in compliance and testing is at an end. (e) If any Eff avg is less than EES, then the basic model is in noncompliance and testing is at an end. [81 FR 89822, Dec. 12, 2016]
