Updated Automatic Power Down Requirements in the ENERGY STAR STB Version 3.0 Specification —October 2, 2012

EPA updated the ENERGY STAR Set-top Box Program Requirements clarifying the Automatic Power Down (APD) requirement of the ENERGY STAR Version 3.0 Set-top Box (STB) specification. The finalized documents are posted below.


Clarification to the Automatic Power Down Requirement - August 31, 2012

The U.S. Environmental Protection Agency (EPA) is making a clarification to the Automatic Power Down (APD) requirement of the ENERGY STAR Version 3.0 Set-top Box (STB) specification in light of numerous questions. Please refer to the memo below.


Updated CSA Reference in the ENERGY STAR Test Method — June 7, 2012

EPA updated the ENERGY STAR Set-top Box Program Requirements so that the Test Method now references the latest version of Canadian Standards Association (CSA) C380-11 test procedure. The use of C380-11 is acceptable in place of the C380-08 edition. This update does not require labs to be re-assessed to the 2011 edition right away. Rather, labs should have the 2011 edition reflected on their next scope according to their existing assessment schedule.


August 12, 2011 - Clarification to the current ENERGY STAR Set-top Box Test Method

EPA has been asked by a certification body whether Set-top Boxes (STBs) undergoing qualification in a multi-room configuration need to also be tested in a single-room/single-output configuration. To streamline the testing process, EPA has updated the test method to allow testing of STBs in a multi-room configuration only, if that is the path to qualification chosen by a manufacturer.
