MULTIPACT^® A - Physical Safety

Applicable standard: “EN 12600”. Glass in building. Pendulum test. Flat glass impact test method and classification.

Test characteristics:

This standard classifies flat glass products used in building.

The testing method consists in releasing a 50kg pendulum cushioned by two pneumatics from different heights and without initial velocity, against a glass specimen measuring approximately 876 x 1938mm.

This test classifies the products into three main groups according to three parameters:

Drop height:               class 1   (1200mm height)
                                class 2   (450 mm height)
                                class 3   (190mm height)

Breakage modes:                               
A = annealed (the glass cracks and many sharp-edged fragments appear)
B = laminate (the glass cracks but the fragments stay together and therefore are not sharp)
C = tempered (the glass disintegrates into relatively harmless particles)

Maximum height without breakage or with a special breakage:Under point “a” chapter 4 of the standard.

The various safety levels are assigned through a combination of these parameters.
This test method increases safety to persons by reducing injury caused by cuts.
