DETERMINATION
THE SURFACE FLAMMABILITY OF
THE NON – METALLIC MATERIALS/PRODUCTS WITH
METHODS ACCORDING TO PN ISO 5658-2, IMO
2010 FTP CODE PART 5 AND
PN-EN 45545-2
Principle
of the test.
The
specimens, in the
presence of the flame initiating the burn,
are exposed to a graded radiant flux field (from
50.5kW/m 2
to 1.5kW/m 2)
supplied by a gas-fired radiant panel. The
flame is spreading along the sample in direction in accordance with
the decreasing flux density thermal, up to the moment of spontaneous
going out.
Stand
for testing surface flammability of materials or products.
Means
are provided for observing the times to ignition, spread and
extinguishment of flame along the length of the specimen as well as
for measuring the compensated millivolt signal of the stack gas
thermocouples as the burning progresses. Experimental results are
reported in terms of:
- critical flux at extinguishment (CFE), kW/m2,
- heat for sustained burning, MJ/m2,
- heat release rate, kW,
- heat release of specimen during burning, MJ.
Test
specimen.
He is
undergoing the examination three representative for given
material/product of the sample about dimensions of 800mmx155mm
about the thickness not crossing 50mm.
In case of textile floor coverings
one should prepare six samples for examinations - three
specimens shall be cut lengthwise and three crosswise.
Applying
research methods:
- shipbuilding (requirements according to IMO 2010 FTP Code Part 5),
- railways (according to: R1, R2, R3, R4, R7, R11, R12 and R17 requirements of the norm PN-EN 45545-2).
