Background of standard formulation and technological evolution

Historical development of stress detection

With the progress of the glass industry, especially the increase in the application demand for high-performance flat glass, the accurate detection of glass stress has become particularly important. The GB/T 36405-2018 standard fills the gap in this field in China, draws on international advanced experience, and combines local reality.

Technical core: birefringence optical path difference

The stress size is determined by measuring the changes in the propagation characteristics of light waves in glass. This method has high sensitivity and is suitable for the detection of various specifications of glass.

Implementation suggestions and precautions

Equipment calibration: Regularly calibrate the polarizer and analyzer to ensure measurement accuracy.
Sample processing: Clean and prepare samples strictly according to standard requirements to avoid impurities interfering with test results.
Environmental control: Maintain constant temperature and humidity conditions during the test to prevent external factors from affecting test accuracy.
