"NEEA recognized during the spring of 2016 that a substantial body of emerging research was pointing to serious flaws in the current US TV test procedure and energy use assumptions. As a result, NEEA commissioned this report, and the new research behind it, to understand how the test procedure could be improved, what qualities a new test clip should possess, and how much progress toward an optimal long-term test procedure could be made in the interim to inform current labeling and incentive programs."
