Positive
Pressure Fire Tests of Door Assemblies
UL 10C
Scope
These methods of fire tests are applicable to swinging door assemblies,
including door frames with lights and panels, of various materials
and types of construction for use in wall openings to retard the
passage of fire. The method does not provide an evaluation of a
swinging door assembly when that assembly is part of a larger assembly
(e.g. sliding fire door assembly), or when it is intended to be
used as an elevator entrance.
Tests made in conformity with these
test methods are intended to register performance during the test
exposure; but such tests shall not be construed as determining suitability
for use after exposure to fire.
It is the intent that tests made
in conformity with these test methods allow for the development
of data to enable regulatory bodies to determine the suitability
of door assemblies for use in locations where fire resistance of
a specified duration is required.
These methods are intended to evaluate
the ability of a door assembly to remain in an opening during a
predetermined test exposure.
The tests expose a specimen to a
standard fire exposure controlled to achieve specified temperatures
throughout a specified time period, followed by the application
of a specified standard fire hose stream. The exposure, however,
is not representative of all fire conditions, which vary with changes
in the amount, nature, and distribution of fire loading, ventilation,
compartment size and configuration, and heat sink characteristics
of the compartment. It does, however, provide a relative measure
of fire performance of door assemblies under these specified fire
exposure conditions.
Any variation from the construction
or conditions that are tested is capable of substantially changing
the performance characteristics of the assembly.
The
methods do not provide the following:
Full information as to performance
of all door assemblies in walls constructed of materials other than
those tested.
Evaluation of the degree by which the door assembly contributes
to the risk of fire by generation of smoke, toxic gases, or other
products of combustion.
A temperature limit on the unexposed side of the door assembly.
A limit on the number of openings allowed in glazed areas or of
the number and size of lateral openings between the door and frame.
Measurement of the degree of control or limitation of the passage
of smoke or products of combustion through the door assembly. Note:
See limitations for the passage of smoke detailed in the Recommended
Practice for the Installation of Smoke-Control Door Assemblies,
NFPA 105.
A product that contains features, characteristics, components, materials,
or systems new or different from those covered by the requirements
in this standard, and that involves a risk of fire or of electric
shock or injury to persons shall be evaluated using appropriate
additional component and end-product requirements to maintain the
level of safety as originally anticipated by the intent of this
standard. A product whose features, characteristics, components,
materials, or systems conflict with specific requirements or provisions
of this standard does not comply with this standard. Revision of
requirements shall be proposed and adopted in conformance with the
methods employed for development, revision, and implementation of
this standard.
