Standard Test Method for Quiet Racks ~ QRA-1107
When you choose a quiet rack you have to consider several factors, thermal capacity, aesthetics, budget and of course, how quiet it will be once your equipment is installed.

To overcome this, Quiet-Rack.com has supported the development of a standard test method which;
