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.
