Purpose: The purpose of this acceptance criteria is
to establish requirements for ICC-ES recognition of low-
profile, raised floor systems under the 1997 Uniform Building
Code™ (UBC) and the 2003 International Building Code®
(IBC).
1.2 Scope: The low-profile, raised floor systems are
placed directly on, and are wholly supported by, a structural
floor assembly complying with the applicable code. The
primary function of the low-profile, raised floor system is to
provide a nonplenum space for distribution of power, voice
or data cabling to work stations.
Class A, low-profile, raised floor systems, as defined in this criteria, may be placed where open spaces below the flooring do not exceed 3,000
square feet (279 m2) when data required in accordance with
Sections 3.1 and 3.3 of this criteria is provided. Class B,
low-profile, raised floor systems, as defined in this criteria,
may be placed where open spaces below the flooring do not
exceed 100 square feet (9.3 m2), when data required in
accordance with Sections 3.2 and 3.3 of this criteria is
provided. Conditions of use for each class are described in Section 6.0.
