2 12600: Testing

3 UNI EN simulazione impatto corpo umano This test classifies rough glass according to its impact performance and the way in which it breaks after impact. It gives results of the type:

UNI EN 12600 results The first number identifies the maximum class of fall height of the pendulum at which the glass either doesn t break or breaks in one of the following ways: A) The glass is

4 UNI EN results The first number identifies the maximum class of fall height of the pendulum at which the glass either doesn t break or breaks in one of the following ways: A) The glass is broken without cracks and/or openings serious enough to allow a sphere with a 76 mm diameter to go through it, after a force of 25 N is applied to it. Classes of height of fall of the pendulum: B) Disintegration of the glass in such a way that the weight of the collected fragments is not heavier than the relative mass of a surface of 6500 mm2 of the tested glass. l mm l mm l mm

5 UNI EN results Safe height of fall The sample doesn t brea The sample breaks but Doesn t produce big or sharp ragments Typical breaking of tempered glass There are no holes nor chips of dangerous sizes Typical breaking of laminated glass

UNI EN 12600 results The letter in the centre identifies the type of breaking: l A

6 UNI EN results The letter in the centre identifies the type of breaking: l A Typical of annealed glass l B Typical of laminated glass l C Typical of tempered glass
