摘要：This invention is directed to a process for determining the temper quality of atempered glass sheet which includes determining the percentages of the thickness of atempered glass sheet which are in compression as well as the sheet's tensile membranestress. The process comprises using a C02 laser beam, either on a painted or unpaintedglass sheet, to shatter the glass sheet and then comparing the number of pulsesrequired for the glass sheet to shatter to data developed which comprises a
correspondence, e.g., a graph, of tensile membrane stress v. compression layer thicknessas a percentage of the total thickness of the glass sheet.
