Abstract:
[ABSTRACT ONLY] This paper discusses the breakthroughs
in science and engineering that have brought fire
testing technology to its current state of maturity and
provides insight into the possibilities for future fire
test development by highlighting some areas where
advancements are needed. The quest for understanding the
properties of fire has been a part of the human
experience since the first primitive human viewed the
glow of a flame potentially 2.5 million years ago,
during the Paleolithic Period. Since these early
observations, humankind slowly developed the knowledge
to use and understand fire. However, the initial
revolution in fire testing did not begin until recently,
in the 19th century, when the basic tools were developed
that allowed for remote measurement of temperatures and
heat flow. Discoveries such as the "thermoelectric
effect" and the development of the First Law of
Thermodynamics led to the creation of tools for
calorimetry providing for the measurement of
temperatures and heat flux. The second revolution in
measuring and understanding fire occurred in the early
20th century with worldwide recognition that
scientifically based fire standards were needed to
protect life and property. At the same time, engineering
innovation developed electromechanical equipment that
could automatically record data measured from fire
experiments. This advancement in data recording allowed
for the detailed study of measured fire behavior. The
third revolution in fire testing (measurement
technology) occurred in the last half of the 20th
century with the development of affordable digital data
logging equipment and computers that enhanced data
analysis and the development of scientifically based
predictive models. Widespread use of technology and
computational methods have opened the theoretical world
which provides insight into the subtle features of fire
dynamics and provides a means for developing a greater
understanding of fire test method performance. Fire
measurement technology now has the scientific and
computational tools to make significant advancements in
the development of fire safety standards. Use of these
tools has directed attention to improvements needed in
testing for structural fire endurance to enhance fire
resistant structural designs. This would include, but
not be limited to, advancements in testing of structural
components, assemblies, and systems under realistic
simulations of fire and load conditions. The objective
for these new tests would be to enhance structural
performance so that uncontrolled building fires result
in burnout without partial or total collapse.
Additionally, these fire measurement technologies would
also lead to improvements in ignition resistant
materials, surface flammability, fire growth, smoke, and
toxic gas production that will save lives and reduce the
high cost of unwanted fires.
