abstract = {The experiments in this contribution have been conducted in
an adapted tube furnace, a new gram scale experiment, based
on the ISO 19700, in which an online mass loss measurement
has been installed. The benefit of this set-up is that it
allows to conduct gramscale pyrolysis experiments under
well-defined boundary conditions. In this set-up, samples
with a length up to 50 cm can be investigated under
different atmospheres and flow rates. In this contribution,
the effect of several experiment parameters on the mass loss
rate is studied. For this purpose, black cast PMMA samples
were heated at a constant heating rate of 5 K/min. The
atmosphere as well as the flow rate through the tube furnace
were varied. Additionally, samples with different
thicknesses were tested. It was observed that unless the
sample autoignites, different flow rates do not result in
differences in the mass loss rate. Nitrogen versus air
atmosphere does make a significant difference on the mass
loss rate. Under air atmosphere the PMMA reacts at lower
temperature than under nitrogen atmosphere. The thicker the
sample, the more the peak mass loss rate shifts to higher
temperature and the lower the normalised peak mass loss
rate.},
