11 Background and Rationale The 2 nd Ed. of CAN/CSA-C22.2 No and 8 th Ed. of ANSI/UL 60065, Audio, video and similar electronic apparatus Safety requirements, which are adoptions, with Canadian and US deviations, of the identically titled IEC (International Electrotechnical Commission) Standard (eighth edition, ) supersede the previous editions, published in 2003 as CAN/CSA-C22.2 No (adopted IEC 60065:2001) including Am. 1 (2005) and Am. 2 (2012) and ANSI/UL th Ed. These will be the last editions of the standards and will be eventually replaced by CAN/CSA C22.2 No and UL (Audio/video, information and communication technology equipment Part 1: Safety requirements) which was published in December 2014 as a Canada/US bi-national standard harmonized with IEC Edition 2. The new standard is based on the principles of hazard based safety engineering, and will be an alternative to CAN/CSA C22.2 No :16 and ANSI/UL over the transitional period. This standard has been reviewed by the CSA Subcommittee on Safety of Electronic Equipment within the field of Audio/Video, Information, and Communication Technology, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. CAN/CSA-C22.2 No :16 and ANSI/UL has also been approved as a National Standard of Canada by the Standards Council of Canada and approved by the American National Standards Institute as an American National Standard. \\REXFPS00\CertData2$\Wgm4\DOC_CTRL\Notices\A-D\AudioandVideoEquipment27.docm Page 11 of 11
