The
Performance Charts below
are divided into two
sections to help you
evaluate the overall
performance of the systems.
The System Performance Criteria
are the most important to
consider because they represent
the performance in a typical
installation.
Panel Only Criteria
such as Concentrated Load
is often used to specify
access floor systems; however,
the test is not representative
of an actual installation
because it is performed with
the panel resting on blocks,
not understructure.

defined in the Technical Resources/Technical

under
"Design Loads". All
other tests are conducted under CISCA's
Recommended Test Procedure for Access
Floors.
