Stain Resistance test ISO 4586-2:2004
To demonstrate the great resistance of Duralight
®
to stains, special tests were carried out using the procedure indicated by the relevant
standard: apply a small quantity of staining agent (2 or 3 drops) at room temperature to the sample surface and cover the resulting
stain with a boron silicate watch glass for approximately 16 hours. Remove the stain with the solvent indicated by the standard and,
finally, clean the surface of the sample with ethanol. After approximately 1 hour, check the surface for any visible stains.

4 Fire resistance
Being a composite material but with a plastic component, Duralight
®
cannot, logically speaking, be considered fireproof.
From the tests performed at the Giordano Institute, it is however classified in class B, the best in terms of fire resistance,
with the emission of non-toxic clear fumes.
Fire resistance classification of construction products UNI EN 13823:2005
Duralight
®
was subjected to flames obtained from the combustion of propane which delivers heat energy of 30.7 ± 2.0 kW.
During 20 minutes of exposure to the flames, the following parameters were noted:
-
production of heat
-
production of smoke
-
lateral spread of flame
-
falling drops and/or particles on fire
Duralight
®
recorded the following parameters in relation to its resistance to fire:
FIGRA 0.2 MJ:
47.605 W/s
FIGRA 0.4 MJ:
47.605 W/s
LFS < end of sample
THR 600s:
7.256 MJ
Also regarding the production of smoke, Duralight
®
falls within the best category, s1, with the following parameters:
SMOGRA:
0.000 m

TSP 600s:

Moreover, no burning drops and/or particles were found (class d0).
Consequently, according to the parameters of the Fire resistance classification of construction products (UNI EN 13501-1:2007),
Duralight
®
falls within Class B – s1, d0.
Test for the ignitability of construction products subjected to the direct attack of flames according to the UNI EN ISO 11925-2:2005 standard
The test monitors two aspects:
-
any combustion of material, if the tip of the flame reaches 150 mm from the point of application
-
any combustion of the filter paper placed under the two samples
Duralight
®
falls within Class B.
Smoke classification
The test, which has the purpose of assigning one of the smoke classes laid down by the NF F16 101 (1988) standard to the material,
analyses the opacity of the smoke emitted into the atmosphere (NF X10-702-2 1994) and the combustion and pyrolysis gases
(NF X70-100 2006).
Duralight
®
was found to belong to Smoke class f0 (the best in the f0-f2 range set by the standard).
During the test on Duralight
®
, the following values were recorded:
-
Front of the flame < 150 mm within 60 sec
-
Ignition of the filter paper: NO
