Introduction to Glass Testing
Glass is an inorganic solid material, usually transparent or translucent in appearance and hard, brittle, and impervious to other natural elements. Items made of glass find use in a range of applications across various industrial and household purposes. Depending on the function, style, and design required, glass is often molded, blown, cut, or pressed in different shapes and sizes.
Performance of glass as a raw material and glass products is evaluated to check their suitability in end-use conditions as per the standards defined.
Glass Testing Methodologies
Glass testing standards support material science labs, material processing businesses, product makers, and other users of glass and glass products in their appropriate fabrication and treatment methods to assure excellent quality and craftsmanship toward safe use. Following are the common tests done for glass and glass items-
- Determination of Internal Pressure Strength of Glass Containers
- Determination of thermal Shock Resistance of Glass Containers
- Polariscopic Examination of Glass Containers
- Determination of Sulfide Resistance of Ceramic Decorations on Glass
- Determination of Strength of Glass by Flexure
- Determination of Softening Point of Glass
- Determination of Annealing Point and Strain Point of Glass by Beam Bending
- Determination of Density of Glass by Buoyancy
These and other test methods evaluate the performance of glass and glass products to effects of weathering, volatile fogging and other environmental exposures, including extreme temperature variations, ultraviolet radiation, and changes in humidity.
