Heat Soaking
JEB Heat Soak Test
The heat soaking process helps to reduce the incidence of spontaneous breakage due to nickel sulfide inclusions and fabrication damage in tempered glass. J.E. Berkowitz adheres to the recognized international standard EN 14179-1:2005 (HST) for heat soaking in an oven certified by FH Munich. The glass is loaded into a special chamber, gradually ramped up to 290 degrees C (+/- 10 degrees C), held there for two hours, then gradually cooled down.
- Offered only in 100% testing
- Reduces probability of breakage from a standard 8 in 1,000 to 5 in 1,000
