NASA's Marshall Space Flight Center (MSFC) maintains a database of materials that have been tested for suitability for use in on-orbit environments. Acoustical materials that are being considered for payload applications must be flight qualified. Ratings of a particular candidate material may be checked in MSFC's MAPTIS database.

A list of fans that have been approved for use in spaceflight hardware has been developed by  Eric Phillips for the
 Acoustics Office at NASA Johnson Space Center. The ATL has a fan test plenum and the experimental capability of characterizing the performance and noise emissions of cooling fans for space flight applications.
