threshold and the contact period when a hot
surface is touched by the skin
Figure 2 - Burn threshold spread when the skin is in contact
with a hot smooth surface made of bare (uncoated)
metal

for metals which are coated by lac of a thickness
of 50 mu m, 100 mu m and 150 mu m

for metals which are coated by Rilsan 2)
(thickness 400 mu m), powder (60 mu m and 90 mu m)
and porcelain enamel (160 mu m)
