Description
Fully tempered glass may break without warning due to the expansion of nickel sulfide inclusions present within float glass. To avoid the risk of spontaneous breakage in fully tempered glass, a good recommendation is to heat soak testing to minimize the risk of spontaneous breakage.
Heat soaking is involves placing the tempered glass inside a chamber and raising the temperature to approximately 550°F to accelerate NiS expansion. This causes glass containing NiS inclusions to break in the heat soak chamber, thus reducing the risk of potential field breakage.
What does heat soaking do?
The heat soaking process puts the glass through a heat cycle to encourage the glass to break under test if it is at risk of inclusions. The result is a pane with a much lower risk of fracture than ‘ordinary’ thermally toughened glass.
Heat soaking significantly reduces the risk of spontaneous breakage 'in situ' of thermally toughened safety glass, and is estimated to eliminate up to 98% of toughened glass panels from production that have potential for spontaneous breakages.
6 projects that should be considered heat soaking glass
1. Frameless glass balustrades: If a frameless, cantilevered or structural glass balustrade shatters, the absence of any kind of frame or handrail could pose a significant safety risk.
2. Infill glass balustrades: If fallout from a glass balustrade is going to be a significant issue, for example if the balustrade is on an overhead balcony or a mezzanine floor, we would recommend heat soaking.
3. Exterior glass doors: A shattered toughened glass door would pose a significant security risk to both commercial and domestic sites.
4. Sloped overhead glazing: The potential risk of shattered toughened glass falling on people from overhead glazing makes this a candidate for heat soaking.
5. Glass spandrels: Shattered toughened glass spandrels could pose a risk to the public from falling glass, as well as being a major inconvenience to replace.
6. Glass shower door: It is very dangerous for glass self exposure when there are someone taking a shower, which will endanger the safety of people. Therefore, it is necessary to use heat soaked tempered glass for shower door.
