Hello Mohammad,

If you refer to the title of the EN standard (i.e. EN-14179) for the Heat Soak Test, it says "Glass in the building- Heat soaked thermally toughened soda lime silicate safety glass" you should have your answer. Technically I think it has to do with the difference in the rate of expansion of NiS inclusion and Glass particles under different stress levels of type FT and HS.

Hi Mohammad,

Yes, you can require the heat soaked test and the tempering stress test report from the manufacturer.
