Subsequently, impacts such as the appearance 1066 moisture spots, water penetration or any pathological manifestations in the laying or coating are measured. Mechanical resistance and elasticity: Impact of hard body: For this purpose the water sprinkling system of the chamber is activated, and a flow of 3.

This adaptation consists in pulling prisms through the increase of concentrated load. It is what guarantees the aesthetic and mechanical conservation of a building besides being directly linked with the maintenance of hygiene and healthiness. The tests stipulated by ABNT NBR simulate the incidence of rain, wind and humidity with the use of a sealing chamber coupled to the sealing system. Sound insulation tests are performed in accordance with ISO Impact of soft body: This test aims to determine the mechanical resistance of the wall to impacts from the use of the system.


Different heights abtn used to simulate different requests.

Impact of actions of suspended loads: The following is a description of each of these tests. The purpose of the test was to verify the characteristics of stability, tightness and thermal insulation of the product, as well as specific behaviors relevant to fire safety.

This test aims to determine the resistance of the system to possible shocks that may occur due to its use. For this, a 40kg bag filled with glass beads is thrown in a pendulum movement against the most unfavorable point of the wall. The test consists of evaluating the performance of the vertical sealing system in case of fire, its fire resistance time and its behavior in relation to structural stability and smoke tightness, as well as thermal insulation.

The tightness of a system is a preponderant factor when it comes to performance. Still regarding this test, the inner face is also subjected to impacts of a 0. To do this, a 1kg steel sphere is projected several times against the abtn face of the wall face that sbnt be exposed to the public and the impact is analyzed according to the criteria of NBR The static pressure to be used in the test is chosen as a result of the region of Brazil, region V, with a pressure of 50 Pa.
