Standard of the tempered glass Up to GB/T9963-1998,IS PRODUCED BY HEATING UP THE FLOATING PRINT GLASS TO APPROXIMATES THE SOFTENING POINT,EVEN RAPIDLY COOLING ON THE SURFACE of glass,causing the surface of glass to have the serious compressed stress,and tensile stress interior,thus enhanced intensity and stability of the glass.when it’s broken by an ecternal force which surpass its intensity,it becomes pellet shape,and is not harmful to people with such security performance. Comparing to common glass with same thickness,its anti-impact intensity and anti-bending stength is 3-5 times.when it’s destructed by external force,the fragment becomes small pieces with obtuse angle,reduce harm to the people. It is mainly used in the high wind pressure or hydraulic pressure building and any places which are possibly hit by people,and all kinds of windows and doors,curtain wall automobile and ship,furniture or interior decoration.Standard of the tempered glass up to GB/T9963-1998 and also meet the standard :DIN 12490.EN 12150 ASTN-E-903(891)-96.BS6206A maximum dimensions:2440x5200mm minimum dimensions:250x250mm the thickness:3-19mm
