Building Roofing Building Materials Combustion Testing Machine

Product description:

The preparation of "Test Methods for External Response to Fire of Roofs and Roof Covering Products" mainly refers to the t1 test method in ENV 1187 and ISO 12468-1. This method specifies 3 test methods under fire conditions. Method A corresponds to t1 in ENV 1187. , Method B and Method C correspond to ISO 12468-1.

Standard:

ISO 12468-1 "Exposure of roofs to external fire - Part 1 - Test methods"；
EN13501-5 "Fire Classification of Building Products or Building Components Part 5: Requirements for Test Classification of Roofs Exposed to External Fire", ASTM E108 "Test Methods for Testing the Burning Properties of Roof Covering Materials".

Technical parameter:

1. The structure of the test sample frame is made of metal square tube welding and angle steel;
2. The test angle of the test sample holder can be adjusted, and the pneumatic adjustment method is adopted. The user only needs to operate the button, which is convenient for the user to use;
3. The adjustable range of the test bracket angle is 0-50 degrees, which meets the test requirements of ISO 12468 Method A and ENV 1187 t1 for the maximum tilt height of the sample to be 45 degrees;
4. The air duct material is SUS304 stainless steel, with a thickness of 2 mm. A fine honeycomb grille is installed in the upper air duct, and a thick honeycomb grille is installed at the outlet;
5. The fan specifications are: the maximum fan speed is 250 cubic meters/min, and the fan motor power is 5.5KW;
6. Fan frequency conversion adjustment device: 3-phase 380V power 5.5KW;
7. The air duct adopts ball screw and servo motor drive mode, which can automatically adjust the angle;
8. The adjustable angle range of the air duct is 0-35 degrees, which meets the method B and method C in ISO 12468;
9. Equipped with 3 impeller anemometers with an accuracy of 0.1m/s;
10. The size of the radiation surface of the radiation plate is 600mmx600mm;
8. The ignition method adopts the electric spark ignition method. At the same time, a thermocouple is provided to monitor the surface temperature of the radiant panel. When the radiant panel is extinguished, the gas can be automatically cut off to avoid the leakage of gas in the non-combustion state;
9. Provide a small stainless steel tube burner, which can be used for shavings combustion test;
10. 1 set of wood stack fire gas burning device;
11. Provide 2 sets of video surveillance devices.
