Fogging Tester Training Material
I. What’s Fogging?
Fogging refers to the evaporation of the volatile components of soft PVC, textiles or
leather. These materials are used to a great extent for the interior fittings and trimmings of
motor vehicles. Under the influence of high temperatures the volatile components
evaporate and condense on the windows and above all on the windscreen, thereby
impairing the view and causing dangerous driving conditions. At the same time the
materials used become more brittle and harder as the volatile components evaporate
resulting in material fatigue and premature aging.
II. Test method：
According to long-time research, two test methods are always needed: that’s:
Method A: Determination of the fogging behavior by measuring the
reflectometer value(R).
According to this procedure, a material sample is temperature controlled at
100℃ for 3 hours. The volatile components condense on a glass plate cooled to 21℃.
In this way the evaporation process which normal takes place in motor vehicles over a
longer period of time as a result of the interior being heated up by the sun’s rays is
simulated in” quick-motion”. The amount of fogging condensation on the glass plate is then
qualitatively recorded by measuring the 60°reflection value. A 60° reflection value of the
same glass plate without condensation serves as a reference.
Method B (gravimetric method): Determination the fogging behavior by
weighting the condensed component (G)
As opposed to process”A”, a sample placed in a beaker is temperature
controlled at 100℃ for 16 hours. The beaker is covered with aluminum foil which has
been previously weighed. The amount of fogging condensation is determined by weighing
the foil again after the test.
