Abstract
The sampling plan for efficiency testing contained in the Supplemental Notice of Proposed Rulemaking (SNOPR),Energy Conservation Program: Test Procedures for Distribution Transformers, are discussed. The proposed sampling plans test for compliance with standards for average energy efficiency. The SNOPR includes: a sampling plan for demonstration of compliance with a represented energy efficiency; criteria for substantiation of an alternative efficiency determination method; and a sampling plan for enforcement testing. Model calculations are presented that estimate the operating characteristics of the sampling plans, that is the probability of demonstrating compliance when testing a specific distribution of efficiencies.Citation
