A NEW TEST PERFORMED IN GERMANY DEMONSTRATES THE GREATER RELIABILITY AND THE BETTER BEHAVIOR OF AB-AR AGAINST THE REST OF STRUCTURAL INTERAYERS.
Pujol has submitted to a new performance test of the structural safety interlayer, AB-AR, this time exposing the specimens to the post-break resistance test at a temperature of 50°C, the test has been carried out in climatic chambers by the Institute of Structural Engineering at the University of the Bundeswehr in Munich, which is the maximum reference worldwide in this field.
For the impact test, double tires were used (according to DIN 18008-4 at 50 kg or 100 kg, air pressure at 20 ° C and 3.5 bar) with a fall height of 900 mm.
For the post-break scenario, several 100 kg concrete cubes were placed on the glass. The position for impact and load (after-break scenario) was the center of the panel and the test program is performed at a temperature of + 50 ° C.
The deflections were measured once the total load time had elapsed (and, therefore, just before increasing the load in the next step of the test program).
The results show that the performance of the laminated glass with the AB-AR interlayer obtain a clearly better result, since, after the fracture of the glass, it can endure without any problems for 24 hours at a temperature of 50 ° C and with a load of 400 Kilos, with a maximum deflection of 210mm, while the tests carried out by other structural products on the market such as ionomers show that they collapse at 53 minutes in the same ambient temperature conditions of 50ºC and only 300 kilos of load.
It is therefore a new demonstration that does nothing more than confirm the excellent quality and guarantee offered by the AB-AR interlayer compared to other ionomers on the market, since AB-AR achieves certifications above the standards of the demanding German market.
