This normally involves hydraulic testing of circular sight glasses and well glasses

Glass is ‘impact tested’ to a predetermined energy value, normally measured in joules, using the free-fall method

Using hydraulic pressure, glass is exposed to a bending pressure to measure / validate the strength of the material for a particular product application

This form of test is performed, using customer-supplied equipment, to verify the strength and resultant breakage pattern under certain explosion conditions

This is a verification process to determine the impact of ∆ shock testing on all glass types
