This document specifies the terms and definitions, basic principles, measuring instruments, measurements, measurement results, and measurement reports of the laser polarization scattering method for measuring glass stress. The method in this document is applicable to the surface stress and stress distribution in the thickness direction of tempered and semi-tempered glass made from soda-lime-silica flat glass, patterned glass, and borosilicate flat glass as original sheets, as well as the glass stress caused by external forces. laboratory and field measurements. Other types of tempered glass can refer to this document.
