Services – Testing and Calibration
We offer the following supplementary services. We are happy to customise our test or calibration procedures to meet the particular needs of our customers.
Test / calibration certificates can be provided, as required.
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.
Thermal Shock Test
This is a verification process to determine the impact of ∆ shock testing on all glass types.
Surface Stress Measurement
The GASP surface polarimeter is based on photoelastic test methods, using light rays traveling along the glass surface.
