ASTM E84 Test Machine Technical parameters :
1. The combustion box is made of stainless steel, with refractory
bricks laid inside; Good thermal insulation performance. The
internal dimension of combustion box is 305mm x 451mm, and the
length is 7.6m;
2. The internal fixtures are made of SUS304 stainless steel, which
is rust and corrosion resistant;
3. The combustion box cover is designed as a whole, and the water
tank seal design is adopted according to the standard. It is
equipped with a 2mm thick 304 stainless steel water seal tank to
ensure no smoke leakage during the test.
4. SUS304 stainless steel thermal insulation body upper cover,
filled with high-temperature insulation materials
5. A ladder type sample installation platform is provided to
facilitate the installation and removal of samples and the
maintenance of furnace channel;
6. Independent multi-function exhaust pressure detector: real-time
monitoring of exhaust pressure changes during testing. The
detection range is 0 ~ 250Pa, the accuracy is ± 0.5Pa, and the
system indicating pressure test accuracy is ± 2Pa;
7. Fan: 380V, 50Hz, 3Kw equipped with frequency converter can
change the wind speed. The maximum flow shall be at least 8000m3/h,
which can timely discharge the flue gas generated under the severe
combustion of the sample out of the room to ensure the safety of
the test;
8. Double ended copper gas burner: the burner is 1320mm away from
the air inlet, which can output standard 5.3MJ/min heat. According
to different standards, the gas flow can be controlled by the mass
flowmeter. The measurement range is 0 ~ 160L/min, which can change
the heat value output of the burner, and the maximum output energy
can reach 100MJ/min;
9. Automatic ignition system: ensure the safety performance of the
test, high voltage igniter, 12KV, 50mA, and the minimum high
voltage of the ignition electrode is 1.8kVp.
