Single Wire Cable Vertical Burning Tester
Single Wire Cable Vertical Burning Tester – ToronFT™ SWC
ToronFT™ SWC Single Wire Cable Vertical Burning Tester is a precision laboratory instrument designed to evaluate the non-flammability properties of single plastic wires and cables across a wide range of wire and cable types including control, cross-linking, elevator, marine, and mining cables. This Single Wire Cable Vertical Burning Tester provides a standardized, IEC-compliant platform for evaluating the vertical flame propagation resistance of individual wire and cable specimens under defined ignition conditions.
The ToronFT™ SWC complies with IEC 60332-1-1, IEC 60332-1-2, and IEC 60332-1-3 — the primary international standards for single wire and cable vertical burning performance testing — and features a precision 1 kW premixed combustion blowtorch, a rotor flowmeter system, and a calibrated compressed air supply, delivering accurate and reproducible single wire vertical burning test results for product certification in North American and international markets.

- Complies with IEC 60332-1-1, -1-2, and -1-3, providing single wire and cable vertical burning test results recognized by international certification bodies and wire cable manufacturers globally
Theory and Method
Single wire and cable vertical burning testing evaluates the ability of an insulated wire or cable specimen to resist vertical flame propagation when exposed to a standardized 1 kW pre-mixed gas/air flame applied at the base of a vertically mounted specimen for a defined duration. After the ignition source is removed, the specimen is observed for continued flame propagation — the test result is expressed as the distance of char above the lower edge of the burner, which must not exceed the limit specified by the applicable IEC 60332-1 standard.
In the ToronFT™ SWC, the 1 kW premixed combustion blowtorch is manufactured to the standard of IEC 60695-11-2, with the height of the blue flame core at 46–78 mm and total flame height of 148–208 mm, made of pure copper for durability and thermal stability. The test box/fume hood (volume 1.0 m³) provides the enclosed vertical burning test environment. Compressed air (0.7 MPa, 500W customer-supplied compressor) and propane gas (purity ≥95%, customer-supplied) are independently metered by separate rotor flowmeters (range adjustable from 1.5 to 15 L/min for each gas), with a precision regulating valve controlling the gas/air mixture and a 0–0.15 MPa pressure gauge for display. This precise gas/air metering ensures the correct 1 kW pre-mixed flame required by IEC 60332-1-2 for standardized single wire and cable vertical burning test results.
