Wire and Cable Heat Release Test Equipment EN50399Introduction :The test system for the simulation of bundles of cable or optical cable medium scale fire tests, test the cable installed on the vertical steel ladder standard, adopt regulations, a source of ignition, is used to evaluate the combustion behavior of the cable and the combustion performance, cable fire can be got through test of initial stage of combustion performance data, through the test of heat release rate reflects the risk of the spread of fire along the cable and fire potential impact on the adjacent area, through the smoke density test fire area of visibility and of the dangers of flue gas to the personal safety.The following characteristics of the cable or cable under specific combustion conditions can be obtained from the test:
The Flame Spread FS
Heat Release Rate the Heat Release Rate HRR
Total Heat Release THR
Smoke Production Rate SPR
Total Smoke Production TSP
Fire Growth Rate FIGRA
Requirements :* Electrical: 110V AC 60Hz / 230V AC 50Hz, 5A
* Ambient Temperature: Operating 10°C to 35°C
* Dimensions: 1120 mm (W) x 2200 mm (D) x 6370 mm (H)
* Gas: air and propaneFeatures :* Test chamber has the dimension of 1,000±100(W) x 2,000±100(D) x 4,000±100(H) mm.
* The bottom surface of the test chamber is higher than the ground while the rear side is supplemented with insulated material to insulate it from heat.
* At the lower section of the test chamber, there is a 800±20(W) x 400±10(D) sized hole at the 150±10mm position from the front side of the chamber to supply the air.
* There is a 300±30(W)x1,000±100(D) sized exhaust hole at the rear corner of the top section of the test chamber to allow emission of the smoke during the test.
* A flame trap is installed at the front side of the burner of the vertical flame spread tester to prevent backfire by propane to ensure the utmost safety.
* Unlike the conventional IEC60332-3 equipment, the vertical flame spread tester records all control and test conditions with the computer to add user friendliness.
* If stop the excessive combustion test due to Water Spray device installed for extinguish.
* The program on the requirement on standard and 70,000Btu/h can be program.
* Wide stainless steel ladder dimensions: 500(W) ×3, 500(H) mm.
* Standard stainless steel ladder dimensions: 800(W) ×3, 500(H).
* Two sets of standard propane burner and venturi mixtures.
* Follow the standard category can program for select a test.
* Exhaust system consists of smoke collection hood,exhaust duct, air inlet system, Centrifugal fan and frequency converter.
* The duct section houses all gas sampling probes, temperature and mass flow probes and has ports for the smoke measuring system.
* Paramagnetic oxygen analyzer, using the method of paramagnetic change to measure the concentration of oxygen in the gas. Concentration range of 0-25%.
* Carbon Dioxide Analyser (infrared) for use in heat release measurement. Concentration range of 0-10%.
* Soot filter, cold trap, drying column, pump and waste regulators for conditioning the sample gases prior to analysis.
* Dataacquisition system and software.
