TESTING THE HEAT
RELEASE RATE, SMOKE PRODUCTION RATE AND THE MASS COMBUSTION RATE WITH
METHODS ACCORDING TO ISO 5660-1, IMO 2010 FTP
CODE PART 10 AND PN-EN
45545-2
Principle of the
test method.
The test
method assess
the heat release rate, dynamic smoke production rate and mass loss
rate of specimens exposed in the horizontal orientation to controlled
levels of heat flux with an external spark igniter.
Stand
for testing heat release rate and smoke production rate of
materials
The heat release
rate is determined by measurement of the oxygen consumption derived
from the oxygen concentration and the flow rate in the combustion
product stream. The test
method is based on the observation that, generally, the net heat of
combustion is proportional to the amount of oxygen required for
combustion. The
relationship is that approximately 3,1×103kJ of heat are released per kilogram of oxygen consumed. The dynamic smoke production rate is
calculated from measurement of the attenuation of a laser light beam
by the combustion product stream.
Test specimen.
He
is undergoing the examination three representative for given
material/product of the sample about dimensions of 100 x100mm
about the thickness not crossing 50mm. For
products with a normal thickness of greater than 50mm, the requisite
specimens shall be obtained by cutting away the unexposed face to
reduce the thickness to 50mm.
Applying research
methods: The scope of appointed parameters and conditions of the
thermal decomposition and burn are being established based on
specifications depending places of applying inspected
material/products:
- shipbuilding (requirements according to IMO 2010 FTP Code Part 10),
- railways (according to: R1, R2, R3, R5, R6, R7, R8, R9, R10, R11, R12, R17, R19, R20 i R21requirements of the norm PN-EN 45545-2).
