Fire Performance of Exterior Building Materials
This modified E108 wall test determines the ability of
a wall system to resist the spread of flames over or through the wall.
Southwest Research Institute (SwRI), a leader in the field of
fire technology for more than 40 years, offers the following test capabilities for the
- ASTM E108 External Fire Testing of Roof Assemblies
Measures the spread of flame and the effects from a burning
brand, intermittent flame, and flying brand of roofing materials. The test establishes the
external fire resistance classification (A, B, or C) of a roofing assembly over
combustible and/or non-combustible substrates.
- Modified ASTM E108
Determines the ability of a wall system to resist spread of
flame over or through the wall. The test consists of exposing vertically mounted wall
systems to a gas flame source. Two separate walls are tested. One wall is tested as is or
"undamaged." A second wall is tested with a portion of the cladding removed to
simulate a "damaged" wall.
- Radiant Panel Wall Ignition Test
Determines the ability of combustible wall systems to resist
ignition and flaming of a wall surface. The test is used to classify the wall for building
code minimum separation distance of adjacent structures based on the maximum tolerable
energy level of radiation heat energy.
The radiant panel measures the ability of combustible
wall systems to resist ignition and flaming of a wall surface.
The ASTM E108 roof test establishes the external fire
resistance classification of a roofing assembly.
These SwRI test facilities are equipped with state-of-the-art
measurement and computer data processing systems that provide fully accredited code
compliance reporting necessary for today's competitive markets.
The SwRI Department of Fire Technology is accredited
by the International Accreditation Service, Inc. (IAS), which encompasses the
three major model building code jurisdictions in the United States, as a
qualified testing laboratory and a third-party quality assurance and inspection
agency in accordance with IAS Report Nos.
The Department has been designated a "Nationally Recognized Testing Laboratory (NRTL)"
by OSHA and has been accredited in all major state and local jurisdictions
throughout the U.S., including the city of Los Angeles, Miami-Dade County, and
the city of New York. The Department has been accepted by the U.S. Coast Guard
to provide testing and follow-up programs in support of Type Approval per the
IMO FTP Code. Internationally, the Department is recognized by The Standards
Council of Canada, Lloyd's Register of Shipping, Det Norske Veritas (DNV), and
the American Bureau of Shipping (ABS).
The SwRI Department of Fire Technology is one of the
world's largest organizations devoted to fire research and testing.
