STAR requirements. A verification testing failure will result if the measured performance fails tomeet any of these ENERGY STAR requirements.
Three Sample Requirements: For the performance criteria above that require multiple sample
testing where it is not obligatory for all samples to meet the ENERGY STAR requirements (e.g.,
at least 90% of samples must meet ENERGY STAR requirements), three samples shall beprocured at once for the purpose of verification testing. For lumen maintenance, all threesamples shall be tested at once unless the manufacturer opts to have lumen maintenancetreated as a one-sample criterion. For the other three-sample requirements, one sample shallbe tested initially. If at any point during the testing that sample fails to meet any of theserequirements, then the two additional samples must have testing initiated immediately for all
three-sample requirements. For these three-sample requirements, if the measured performanceof two or more samples fails to meet any of these ENERGY STAR requirements, it isconsidered a testing failure.
For both one-sample and three-sample requirements, even if a testing failure occurs, testing
shall continue to completion, unless the manufacturer opts to have the model disqualified and tocease testing, which it may do at any point in the verification testing process.
Reporting to EPA
Consistent with procedures for other ENERGY STAR product categories, CBs are required toreport testing failures on any of the performance requirements to enforcement@energystar.gov
within two days of determining a testing failure, and include with this submission all relevant test
reports. EPA will then notify the manufacturer per the ENERGY STAR Disqualification
Procedures.
Until further notice, CBs shall also submit test results and associated reports for luminaires
meeting all applicable ENERGY STAR requirements to certification@energystar.gov within twoweeks of receiving complete test results. [Note: EPA will reconsider the necessity of thisrequirement after gaining greater experience with CB-administered verification testing for theseproduct types.]2
