Heat Soak Testing

Contour's Heat Soak Testing

For additional peace of mind, Contour Glass offers heat soak testing (HST) for tempered glass in sizes up to 100” x 148” and in thicknesses from 1/8” to 3/8”.  Nickel sulfide inclusions are a leading cause in the spontaneous breakage of tempered glass.  Heat soak testing accelerates the expansion of nickel sulfide inclusions, which substantially increases the probability of forced breakage during the testing process and minimizes the chances of spontaneous breakage after installation.
