Nowadays the climatic tests on materials have become very numerous and every production sector must know dozens and dozens of tests approved by various international organizations.
Some of these tests, however, acquire a certain notoriety in the sector and even funny nicknames. This is the case of the "Tropical Test" Method for the hydrolysis test, known in the field as "Jungle Test".
Let's find out what it is.
What is the Jungle Test for?
Like many other sectors, the textile industry has its own specific climatic tests, among which those of accelerated aging stand out, which we have talked about extensively on our pages.
In general, the accelerated aging test serves to verify how much a given material resists the influence of atmospheric agents which are adjusted upwards to simulate an exposure much longer than the duration of the tests themselves.
Accelerated aging tests for a sector, in turn, are distinguished by type of fabrics and test methods. The ISO 1419 standard has 4 distinct methods including the famous Method C "Tropical Test" which in the environment is nicknamed "Jungle Test".
We talk about tropicality and jungle because the test measures resistance to hydrolysis, that is, to very hot and humid environments such as those typical of tropical jungles!
How the Jungle Test according to ISO 1419 works.
The ISO 1419 standard is recommended by the ACT, Association of Contract Textile, one of the most important industry associations and certifies the approval of fabrics for various accelerated aging tests including resistance to hydrolysis performed through Method C, the Jungle Test .
To perform the Jungle Test, a climatic chamber with temperature and humidity control is required because these two parameters are essential to reproduce the "tropical environment" simulated by the test.
The sample is placed in the test chamber with a temperature of 70 ° and a relative humidity of 95%, ie close to saturation.
It is then examined visually against a control sample at the end of each week for a predetermined number of weeks, or until the sample suffers significant damage; such as: surface cracking, delamination of the film layer or extreme changes in color and gloss level.
The Jungle Test does not prescribe a minimum duration of the test but it is generally accepted that a material intended for the private market must last for at least 3 weeks, while one intended for the commercial market, at least 5.
The FDM Climatic Chamber for the Jungle Test according to ISO1419
The FDM climatic chamber for the humidity and temperature test is the ideal tool for performing the hydrolysis resistance test also known as the Jungle Test.
Our climatic chambers meet the test requirements by exceeding 70 ° in temperature and 98% relative humidity.
Moreover, thanks to the innovative revoFACE controller, the cycles are perfectly programmable for the duration of all the weeks necessary for the accelerated aging test on the sample.
