Abstract:
Toughened glass acquires a degree
of strength for excess of the strength of
normal glass sheet or plate glass, which
if broken shatters into small and
comparatively harmless pieces. It is
claimed that the resistance to
mechanical stock of toughened plate
glass is 4 to 5 times more than that of
ordinary plate glass. A toughened glass
has better resistance to the vibration,
mechanical shock and abrasion.
Toughend Glass has to pass the
following important tests:
i. Transfer strength test on sheets
on simply supplied (Modules of
rupture and electricity)
ii. Impact test: By following weight
on sheets supported on two
wooden battens
iii. Impact by falling weight on sheet
evenly bedded (on putty)
