HST - test

Self-destruction of tempered glass is a problem that can occur in a finished facade with a probability of 1 case per 8 tons of glass. The cause of self-destruction is a nickel particle that gets into the glass with sand and later becomes sulfide. In untempered glass, this particle does not manifest itself in any way, so the glass manufacturer cannot detect it. During tempering, the nickel sulfide particle does not have time to cool down with the rest of the glass. The glass holds it in a tense state. Later, in a month, a year, two years, this particle, if it is in the glass, will definitely destroy it. After tempering the glass, we can artificially create conditions for its destruction if there is nickel sulfide in the glass. This is the HST test, in which tempered glass is held for 2 hours at a temperature of 260°C. We conduct the test to order and provide guarantees that self-destruction will not occur. By ordering HST, you eliminate the possible problems of difficult dismantling of a broken glass unit and avoid the risk of small glass fragments falling from a height. The test is the final step to obtaining completely safe glass
