CROSS UK Report 1135

摘要

A reporter believes from their experience that toughened glass that has been heat-soaked in compliance with BS EN 14179 is many times less likely to shatter spontaneously than toughened glass that has not been heat-soaked. Consequently, many designers specify heat-soaked toughened glass to minimise the risk of broken toughened glass falling from buildings. Nevertheless, glass has fallen from buildings - there have been near misses and people have been alarmed by breakages. According to the reporter, failures caused by nickel sulphide inclusions (the impurities that heat-soaking counteracts) are very rare in heat-soaked toughened glass provided by most processors.
