Bunched Cable Vertical Flame Spread Tester

Bunched Cable Vertical Flame Spread Tester, VTFT 2008,


IEC 60332-3, KS C IEC 60332-3-10, 21~25 Bunched Cable Vertical Flame Spread Tester is a series conforming to IEC 60332-3-10, KS C IEC 60332-3-21~25 (Category A~D) standard. The test measures the expansion of vertical flame to the electronically or optically vertical cable or wire using the standard ignition source while supplying a certain amount of air to a chamber of a certain volume.


The product is manufactured so that it will conform to IEEE383 (IEEE1202) when the

standard burner is adjusted by 20 degrees


Standard

• IEC 60332-3-10 :Test on Electric cables under fire conditionspart 3 : Test on bunched wires or cables

• KS C IEC 60332-3-21 : Category A F/R

• KS C IEC 60332-3-22 : Category A

Features

• 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)x 1,000±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.

• The air and gas flow rate to the burner must be compensated for the temperature and pressure. While many conventional systems ignore such compensation, the equipment from FESTEC International automatically compensates it by the computer program.
