What are the test methods for tempered glass?

Impact resistance test, atmospheric pressure test, light test.

Generally, the most important thing to test tempered glass is to test its strength, that is, impact resistance. In this regard, there are many physical testing methods, that is, the collision of heavy objects with glass to measure strength. However, this test method is destructive, so it can't be tested comprehensively and can only be sampled. In addition, the strength of glass can be tested by atmospheric pressure to better control the strength.

There are many physical detection methods, as long as you can ensure that the gravity used to test the strength of tempered glass can be controlled and calculated. Generally, there will be professional instrument testing.

If you are at home, use a rubber hammer to test whether the glass you bought is strong enough. Generally, you can distinguish ordinary glass from tempered glass by its thickness. If the production of tempered glass needs to be tested, there will be quality inspection. Just flip through the file, which will clearly write where the test items are. As long as the tempered glass has passed the standard certification, it is up to standard, and no additional testing is needed.

However, if the purchased tempered glass has not been tested and you want to test it yourself, you can only look at its tolerance. However, this test is risky and destructive, so it is not recommended. You should buy tempered glass from regular manufacturers.
