During a heat soak test, the safety glasses containing Nickel Sulfide inclusions crack, leaving only correct glasses to be delivered to the customer. By executing this test, it is possible to avoid any danger caused by spontaneously glass breakage.

A unique feature of the HOAF laminating kilns, is the fact that they can be applied for the heat soak test as well. This results in the following advantages:

• an investment in a special heat soak kiln is not unnecessary
• possibility of heat soak testing according to EN, DIN and BS
• low operational costs

The HOAF laminating kilns are conform EN 14179-2005 standards, for heat soak testing of safety glass
