Heat release and smoke production according to ISO 5660-1
(3 appendices)
Introduction
SP has by request of Finsa Dpto. De Idi + Calidad performed a fire test according to
ISO 5660-1. The purpose of the test is to form a basis for technical fire classification.
Product
According to the client:
MDF board called ”Fibracolour Negro IGNIFUGO”.
The product has a nominal area weight of 14 kg/m2 and a nominal thickness of 19 mm. The
product has a black colour.
The product has a nominal area weight of 8.5 kg/m2 and a nominal thickness of 10 mm. The
product has a black colour.
Manufacturer
Finsa Dpto. De Idi + Calidad, A Coruna, Spain.
Sampling
The sample was delivered by the client. It is not known to SP Fire Research if the product
received is representative of the mean production characteristics.
The sample was received May 21, 2015 at SP Fire Research.
Test procedure
In the Cone Calorimeter, ISO 5660, specimens of 0.1 by 0.1 m are exposed to controlled levels
of radiant heating. The specimen surface is therefore heated up and an external spark ignitor
ignites the pyrolysis gases from the specimen. The gases are collected by a hood and extracted
by an exhaust fan.
The heat release rate (HRR) is determined by measurements of the oxygen consumption
derived from the oxygen concentration and the flow rate in the exhaust duct. The specimen is
placed on a load cell during testing. A retainer frame covers the periphery of the specimen.
Smoke production rate is measured with a laser system.

The following classification has been assessed in the accordance with the New Zealand
Building Code Verification Method C/VM2 Appendix A. Establishing Group numbers for
lining materials. Calculation were carried out according to section A1.3 for predicting a
material´s group number for each specimen tested.

The tested sample recorded an average specific extinction area less than 250 m2/kg. In
accordance with Verification Method C/VM2 Appendix A, samples achieving either a Group
number classification 1 or 2, and with an average specific extinction area less than 250 m2/kg
are identified with “S” post-script to the Group number.
Assessment
The cone calorimeter testing was carried out on the specimens. For the purposes of compliance
with the NZBC Verification Method C/VM2 Appendix A, the following classification is
considered applicable to the material “Fibracolour Negro IGNIFUGO, 10 – 19 mm”.

Parameter
Explanation
Test start
The test specimen is subjected to the irradiance and the clock is started.
tflash
Time from test start until flames with shorter duration than 1 s.
tign
Time from test start until sustained flaming with duration more than 10 s.
Text
Time from test start until the flames have died out.
End of test
Defined as the time when both, the product has been extinguished for 2 minutes,
and the mass loss is less than 150 g/m2 during 1 minute.
Ttest
Test time. From test start until end of test.
qmax
Peak heat release rate during the entire test.
q180
Average heat release rate during 3 minutes from ignition. If the test is terminated
before, the heat release rate is taken as 0 from the end of test.
q300
Average heat release rate during 5 minutes from ignition. If the test is terminated
before, the heat release rate is taken as 0 from the end of test.
THR
Total Heat Released from test start until end of test.
SPRmax
Peak Smoke Production Rate from test start until end of test.
TSP
Total Smoke Produced from test start until end of test.
M0
Mass of specimen.
Ms
Mass of specimen at sustained flaming.
Mf
Mass of specimen at the end of the test.
MLRign-end
Mass Loss Rate. Average mass loss rate from ignition until end of test.
MLR10-90
Mass Loss Rate. Average mass loss rate between 10% and 90% of mass loss.
TML
Total mass loss from ignition until end of test.
Hc
Effective heat of combustion calculated as the ratio between total energy released
and total mass loss calculated from ignition until end of test.
MARHE
Maximum Average Rate of Heat Emission defined as the maximum of the
function (cumulative heat release between t = 0 and time = t) divided by (time =
t).
V
Volume flow rate in exhaust duct. Average during the test.
