External test institutes – testing against extreme weather conditions
tesa® ACXplus 7078 has been tested at both the University of Chile and at James Cook University in Australia for its suitability in different construction applications during extreme weather conditions.
Extreme weather conditions are an inevitable part of life in some parts of the world. For these countries, our products are tested for their performance during natural disasters. Establishing the best tape solution for an application is a very important part of what we do. Whilst some tests can be done internally, more specialist tests require an external test institute. tesa® ACXplus 7078 has been tested at both the University of Chile and at James Cook University in Australia for its suitability in different construction applications during extreme weather conditions.
tesa® ACXplus 7078 Passes the Earthquake Test in Chile
DICTUC is a subsidiary of the University of Chile that provides consultation regarding seismic analyses for construction. Society profits from the technologies created at this university, which is noted for its expertise. DICTUC tested tesa® ACXplus 7078, a double-sided adhesive tape, as part of a curtain wall system. DICTUC used the standard recommended test method for evaluating curtain walls subjected to seismic force. This is called the AAMA 501.6-09 testing method. The testing requirements were based on data recorded during the magnitude 8.8 earthquake which hit Chile in 2010.
The test simulated the effects an earthquake would have on a twenty floor building. It subjected the tesa tape and the framed glass panels to a shock 60% higher than that experienced in February 2010, with 50 mm movement up-and-down and 42 mm of side-to-side movement.
After the test, the tesa tape and the framed glass were tested thoroughly. No damage, collapse, detachment, or failure of any kind could be found. It was an utter success for tesa® ACXplus 7078, proving its suitability for applications in this area.
tesa® ACXplus 7078 Withstand Cyclone and Heavy Wind Conditions
The James Cook University’s Cyclone Testing Station in Australia consists of a team dedicated to minimizing loss and suffering caused by high-wind events by ensuring that construction materials are tested to the highest degree. In 2014, the Cyclone Testing Station assessed how effectively tesa® ACXplus 7078 worked on walling applications during cyclone and heavy wind conditions.
For these tests, aluminium composite panels were used, consisting of two thin sheets of aluminium with a mineral core. They were attached to top hat battens before becoming the “lid” of a pressure chamber. A uniform pressure was then applied to the internal face of the aluminium composite panel by large centrifuge fans. The test pressure was adjusted to compensate for the panels being tested horizontally, as they would eventually be used vertically. The air pressure was slowly increased until it was such that the deflection limit was reached, or the panels showed signs of permanent deformation.
The acceptance criteria for this test is that the complete test element remains in position with no permanent distortion, fracture, or damage. No detachment of panels from the adhesive or the adhesive from the top hat battens was detectable on tesa® ACXplus or aluminium composite panels. The test was a complete success for this construction.
This type of testing represents a great opportunity for us: it allows us to gain knowledge and data that is relevant worldwide. In this way, we can reach our goals of providing the market with solutions proven to work in real-world conditions.
