Heat-Soak-Test

The heat-soak test is the hot storage test for thermally toughened safety glass and serves to avoid so-called spontaneous breaks. In this hot air test, the tempered glass is exposed to a heat load of 290 °C for several hours in a special heat-soak oven. The test process is logged. The heat-soak test is mandatory, for example, for fall safe glazing made of thermally toughened safety glass and for thermally toughened safety glass facade panels.
