Standard Test Method for Measurement of Glass Stress—Optical Coefficient

ASTM Vol.15.02 (2022)
Stress-optical coefficients are used in the determination of stress in glass. They are particularly useful in determining the magnitude of thermal residual stresses for annealing or pre-stressing (tempering) glass. As such, they can be important in specification acceptance.
