4 NATURE OF TEST
The tests have been carried out in accordance with EN 13823:2002 for validation of theDanish proposal described in the FRG document RG N333.
5 SAMPLE
Danish Institute of Fire and Security Technology (DIFT) received the following sample:
16 slabs of expanded polystyrene, each with dimensions 1197 x 596 x 80.0 mm.
Density at 20°C (undried): 15.8 kg/m³ at the state of receipt determined by weight andmeasures of the sample.
Three test specimens were prepared from the sample.
A standard mounting of specimen was carried out in accordance with clause 5.2.2 of EN13823 as follows:
File No. DZ67550f

Page 3 of 6
Thickness ofproduct: 80.0 mm
Mounting: Standard mounting option b) in clause 5.2.2 of EN 13823. See enclo-sure 1.
Substrate: 12 mm calcium silicate board, cf. EN 13238.
Fixing means: The slabs were glued to the 12 mm calcium silicate board with ISOFIXUniversalklæber. The applied amount in weight per unit area ofISOFIX Universalklæber in wet and dried condition was determined to1.7 kg/m2 and 0.9 kg/m2, respectively.
ISOFIX Universalklæber is a water glass based adhesive.
Chemical composition:
Siliciumdioxide SiO2 : 33.0 %Aluminiumoxide Al2O3 : 15.0 %Ferrioxide Fe2O3 : 0.4 %Natriumoxide Na2O : 4.0 %Kaliumoxide K2O : 1.0 %Water H2O : 46.6 %
Thermocouples: 3 thermocouples were fixed between product and substrate in thefollowing 3 positions on the long wing:
T160: - positioned 160 mm from the upper edge of the burner and200 mm from the corner.
T300: - positioned 300 mm from the upper edge of the burner and200 mm from the corner.
T750: - positioned 750 mm from the upper edge of the burner and200 mm from the corner.
6 CONDITIONING
No conditioning of specimens was conducted.

7 TEST METHOD
The tests were performed in accordance with:
EN 13823:2002 Reaction to fire tests for building products �Building products excluding floorings exposed to the thermalattack by a single burning item.
8 TEST RESULTS
Date of test: 2003-12-15
2 tests were performed.
Test F1 was terminated before the nominal exposure period in accordance with clause 8.5b inEN 13823. A third test was not carried out.
During each test the following measurements were made: Volume flow in the exhaust duct,production of carbon dioxide, concentration of oxygen, and production of light-obscuringsmoke. Based on these measurements the rate of heat release and the rate of smoke produc-tion were calculated.
The graphs, enclosure 2-5, show for test F2:
Enclosure 2- Average Heat Release Rate HRRav(t)- Total Heat Release THR (t)
Enclosure 3- Average Heat Release Rate per unit time [1000 x HRRav(t)/(t-300)]- Figra0.2MJ-values
Enclosure 4- Figra0.4 MJ-values- Smoke Production Rate SPRav(t)
Enclosure 5- Total Smoke Production TSP(t)- Smoke Production Rate per unit time [10000 x SPRav(t)/(t-300)]
The graphs, enclosure 6-7, show the measured temperatures for test F1 and test F2:
Enclosure 6- T160 temperature (temperature measured between product and substrate, 160 mm
from upper edge of the burner and 200 mm from the corner)- T300 temperature (temperature measured between product and substrate, 300 mm
from upper edge of the burner and 200 mm from the corner)
