Abstract:
It may seem surprising that there have not been a
significant number of studies reported in the literature
where results from 3 or more HRR apparatuses are
directly compared against each other. The best-known
such study was one by Ostman and co-workers in 1985. In
that study three apparatuses were examined against a
wide range of test materials. The application of these
findings was somewhat limited, however, since two of the
three methods studied (the STFI apparatus and the OSU
apparatus modified for oxygen consumption sensing) were
not standard equipment or procedures. Only the third
apparatus, the Cone Calorimeter, was a common apparatus
used in its standard form. More specifically, all three
methods examined by Ostman used oxygen consumption as
the measurement principles. Thus, differences seen
between the apparatuses were due to such secondary
effects as specimen size, sample holder arrangements,
ignition mechanisms, and errors in calibration. The
opportunity was still to come to subject a range to
materials to apparatuses which differed in their very
measurement principles, in addition to being of
mechanically varied designs.
