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.
