Product Introduction
The thermal radiation melt drop tester is developed according to
the French building materials and railway vehicle flame retardant
test standard NF P92-505, and it meets the requirements of the
European Union 95/28/EC automotive interior materials fire test
standard; the principle of the test is that: the sample is placed
horizontally on the sample rack, the vertical distance of 30mm at
its office, horizontal level of a power of 500W electric radiators,
heat the sample to impose a certain amount of radiation in the
sample under 300mm vertical distance by placing a receiving tray,
drip tray lighted place for lint (asbestos gasket), test 10min.
The dripping test according to NF P 92-505 is a reaction to fire
complementary test for M classification of building and fitting
materials. It is used for thermal melting materials for which some
inflamed or not dripping, produced by a heating source, were
noticed during the main test. This one can be either the electrical
burner test for flexible and thin materials (NF P 92-503), or the
radiation test (epiradiator cabinet) for rigid or flexible and
thick materials (NF P 92-501).
In principle, cotton wool inflammation at the dripping test leads
to M4 classification. If the cotton wool is not inflamed at the
dripping test, the classification obtained at the main test is
maintained or the material is downgraded according to whether there
was some uninflamed or inflamed dripping during this same main
test. In case of holing without inflammation or with short time
inflammation at the main test, this outline is also applied to the
complementary flame persistency test (NF P 92-504) when there was
again some uninflamed or inflamed dripping during this
complementary test.
Performance characteristics
1. The stainless steel heat radiator bracket can be rotated 90
degrees for quick and easy testing;
2. This metl drop tester is equipped with a measuring tool for the
height of the sample from the heat radiation device, which is
convenient to adjust the test height;
3. Epiradiator heat radiation device, which can provide 30KW/m2
heat radiation flux;
4. The panel displays the operating power value of the heat
radiation device, eliminating frequent calibration procedures;
5. The power controller controls the radiation output and can
adjust the radiation flux of the heat radiation device;
6. The metl drop tester is equipped with sample and cotton tray,
the height can be adjusted and it is easy to evacuate the radiation
source.
