Revision Summary
16 February 2009 Revised the "Next Planned Update". Reaffirmed the contents of the document, and reissued with minor changes.
Streamline this document with the UL requirements for TC cables and allow Type MC cables with aluminum armor for offshore applications due to its light weight.
7 September 2009 Minor revision to meet the triennial revision and to streamline with SAES-J-904 which recently went through a major revision.
