Revision of Existing Standard
Under ANSI and VITA rules every 5 years an approved standard must be reaffirmed, revised, placed in stabilized maintenance or withdrawn. This standard has been revised; hence it has been put forth for approval of the revisions. The VITA 48.5 working group has completed the draft and has voted to take this draft through to the VITA public review approval process for eventual ANSI recognition.
Consensus body registration for voting for VITA approval of the following draft standard for the approval process is now open:
Consensus body registration for voting to approve this revised standard is now open.
Draft/VITA 48.5-202x - Mechanical Standard for Electronic Plug-in units Using Air Flow Through Cooling
Abstract: This standard establishes the design requirements for an air-flow-through cooled Plug-In Module with a form factor as close to 6U as possible while retaining the VITA 46 connector layout. Unlike ANSI/VITA 48.1, which uses cooling air impinged directly upon the components and circuit boards, this Plug-In Module uses a compact core heat exchanger located within the central heat sink of the unit. This revision is a major one that includes the addition of 3U form factor, discrete backplane pitches, and a larger air inlet opening, as well as air seal dimensional changes. As a result, this revision is NOT interoperable with the previous (2010) revision and supersedes it. It is expected that new designs/implementations will use this revision.
