International Building Code 1407.10

Type I, II, III and IV construction. Where installed
on buildings of Type I, II, III and IV construction, MCM systems
shall comply with Sections 1407.10.1 through 1407.10.4,
or 1407.11.

Surface-burning characteristics. MCM shall
have a flame spread index of not more than 25 and a
smoke-developed index of not more than 450 when tested as
an assembly in the maximum thickness intended for use in
accordance with ASTM E 84.

Thermal barriers. MCM shall be separated
from the interior of a building by an approved thermal barrier
consisting of 0.5-inch (12.7 mm) gypsum wallboard or
equivalent thermal barrier material that will limit the average
temperature rise of the unexposed surface to not more
than 250F (121C) after 15 minutes of fire exposure in
accordance with the standard time-temperature curve of
ASTME 119. The thermal barrier shall be installed in such a
manner that it will remain in place for not less than 15 minutes
based on a test conducted in accordance withUL1715.

Thermal barrier not required. The thermal
barrier specified for MCM in Section 1407.10.2 is not
required where:
1. The MCM system is specifically approved based on
tests conducted in accordance with UL 1040 or UL
1715. Such testing shall be performed with theMCM
in the maximum thickness intended for use. The
MCM system shall include seams, joints and other

typical details used in the installation and shall be
tested in the manner intended for use.
2. The MCMis used as elements of balconies and similar
projections, architectural trim or embellishments.

Full-scale tests. The MCM exterior wall assembly
shall be tested in accordance with, and comply with, the
acceptance criteria of NFPA 285. Such testing shall be performed
on theMCMsystem with theMCMin the maximum
thickness intended for use.
