We frequently receive inquiries about whether optical and thermal property testing can be performed on shattered tempered glass pieces.
However, our instruments require a minimum sample size of 1 inch (25 mm) to obtain accurate results. Since shattered tempered glass pieces are typically smaller than this, it is impractical to conduct the tests on such small fragments.
For tempered glasses, the most practical solution is to remove a full and intact piece of glass from the building for testing, as detailed on this page.
