Heat Soak Test
In line with project specifications and requests, Camglass applies the Heat Soak Test to fully tempered glass in accordance with EN 14179. The test aims to reduce the risk of spontaneous breakage in tempered glass caused by nickel sulphide (NiS) inclusions.
After tempering, the glass is placed in the test furnace and subjected to a thermal cycle consisting of controlled heating, holding at a defined temperature and controlled cooling. This process ensures that panes containing critical inclusions are separated in the production environment before reaching the site.
Depending on the product build-up, tested glass is dispatched as single glazing or transferred to lamination and insulating glass production.

Frequently Asked Questions
Which glass is the Heat Soak Test applied to?
The test is applied to fully tempered flat glass. Heat soak tested glass can be used as single glazing or in laminated and insulating glass units.
How is the Heat Soak Test carried out?
After tempering, the glass is placed in the test furnace and subjected to a thermal cycle of controlled heating, holding and cooling in accordance with EN 14179. Panes containing nickel sulphide inclusions are made to break in the production environment during this process.
How can I request the Heat Soak Test?
The Heat Soak Test is applied in line with project specifications and requests. If you state your requirement at the quotation stage, suitability is evaluated according to size, thickness and product build-up.
