## Comparison of DOE’s SNOPR TV Test Procedure with CEA

- 2037 -A

This document compares DOE’s proposed test procedure from the Supplemental Notice of Proposed Rulemaking (SNOPR) for Television Sets (TVs), ( 78 FR 15807, March 12, 2013 ) , to the Consumer Electronics Association’s (CEA) draft CEA -2037-A WD3.5 test procedure , “Determination of Television Set Power Consumption,” updated on October 11, 2012.

This comparison highlights only the differences between the two documents. The first column shows the regulatory text from th e SNOPR, while the second column contains a citation from the relevant section in the CEA test procedure for comparison. An empty cell denotes a topic not covered by the test procedure, while a cell with red text highlights any difference in language between in the SNOPR and CEA.

Note that the page number references are to the page numbers of the pre-publication version of the SNOPR

. In this document, the proposed regulatory text begins on page 81. The discussion section of the SNOPR, page 15 to 68 of this document, provides a detailed explanation of DOE’s new proposal. It should also be noted that the formatting of the pre -publication NOPR is the only difference between this version and the version published in the Federal Register. The text is the same.
