Different heights are used to simulate different requests. It is what guarantees the aesthetic and mechanical conservation of a building besides being directly linked with the maintenance of hygiene and healthiness. The tightness of a system is a preponderant factor when it comes to performance.
NBR 14432 Resistencia ao fogo
Mechanical resistance and elasticity: This test aims to determine the mechanical resistance of the wall to impacts from the use of the system. Impact of hard body: For this, a 40kg bag filled with glass beads is thrown in a pendulum movement against the most unfavorable point of the wall.
Sound insulation tests are performed in accordance with ISO This test aims to determine the resistance of the system to possible shocks nb may occur due to its use. Impact of actions of suspended loads: To do this, a 1kg steel sphere is projected several times against the external face of the wall face that would be exposed to the public and the impact is analyzed according to the criteria of NBR Impact of soft body: 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.
For this purpose the water sprinkling system of the chamber is activated, and a flow of 3.
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. The following is a description of each of these tests.
Still regarding this test, the inner face is also subjected to impacts of a 0.

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.
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 adaptation consists in pulling prisms through the increase of concentrated load. Subsequently, impacts such as the appearance of moisture spots, water penetration or any pathological manifestations in the laying or coating are measured.
