Tempered Glass Impact Strength Test Equipment Function: Determining the resistance of glazing material to impact by the penetration method. Principle: The specimen is supported vertically in a steel frame and an impact shot bag is released from a pre-determined height to strike the specimen at the centre. The height is progressively increased until fracture occurs. Related Standards: AS/NZS 2208 Safety glazing materials in buildings â??
