Method for impact-testing chemically strengthened glass, method for reproducing cracks in chemically strengthened glass, and method for manufacturing chemically strengthened glass

摘要

A chemically strengthened glass is disposed on a base, and an impacting object is dropped from above in a state where one surface of the chemically strengthened glass is in contact with an abrasive surface of a sandpaper containing an abrasive having a size of not smaller than a depth of a compressive stress layer.

1. A method for impact-testing a flat chemically strengthened glass having formed on a surface thereof a compressive stress layer,
the method comprising disposing the chemically strengthened glass on a base, and dropping a sphere from above in a state where one surface of the chemically strengthened glass is in contact with an abrasive surface of a sandpaper containing an abrasive having a size of not smaller than a depth of the compressive stress layer, wherein said sphere makes contact with a surface of said sandpaper which is opposite said abrasive surface.
