Applications
This cable flammability tester is used by cable manufacturers, electrical product manufacturers and testing laboratories for:
- Evaluating insulation materials during wire and cable development.
- Production quality control and incoming inspection.
- Assessing wiring used in lighting, household appliances and low-voltage electrical equipment.
- Testing wires and cables used in motors, power tools, electronic instruments and electrical connectors.
Key Features
- Two burner sizes: Bunsen burners with nominal internal diameters of 2 mm and 9.5 mm support different test arrangements.
- Adjustable flame height and timing: Set the flame height and ignition time to suit the selected procedure.
- Burning-time recording: The timer records elapsed burning time automatically, with manual stopping by the operator.
- Observation window: Monitor the specimen and its burning behavior during the test.

How the Vertical Flame Test Works
A prepared specimen is mounted vertically and exposed to a specified flame for a set duration. The operator records the required observations and examines the specimen to assess flame propagation.
- Prepare and mount the specimen. Follow the conditioning, specimen length and mounting requirements of the selected method.
- Set and check the flame. Fit the appropriate burner, adjust the gas and air settings, and complete the prescribed flame checks.
- Apply the flame. Use the position, angle and exposure time required by the test procedure.
- Assess the result. Record the required timing and observations, inspect the charred area, and compare the result with the applicable acceptance criteria.

Installation Requirements
The standard configuration operates on AC 220 V, 50 Hz, with an electrical power requirement of ≤500 W. The power supply can be customized to suit local requirements.
Installation requires suitable gas and air supplies and laboratory fume extraction that does not disturb the flame or test conditions.

Frequently Asked Questions
1. What is a cable flame test chamber?
A cable flame test chamber evaluates the resistance of wires and cables to flame propagation. This model tests a single wire or cable mounted vertically.
2. What is the difference between IEC 60332-1-2 and IEC 60332-2-2?
IEC 60332-1-2 uses a 1 kW premixed flame. IEC 60332-2-2 uses a diffusion flame for small wires or cables when the 1 kW method is unsuitable.
3. Does the chamber determine pass or fail automatically?
No. The chamber records burning time, while the operator assesses the specimen against the applicable acceptance criteria.
4. Can this cable flame tester test bunched cables?
This chamber tests individual wires and cables. Bunched-cable flame propagation testing requires different equipment and procedures, such as those in the IEC 60332-3 series.
5. Does the 1 kW test flame require a 1 kW electrical supply?
No. The 1 kW rating refers to the nominal heat output of the flame. The chamber’s electrical power requirement is ≤500 W.
6. Can I request a customized configuration?
Yes. BONAD can assess your testing requirements and develop a customized equipment solution for your application.
