The Single Wire Cable Burning Tester is a precision flammability test system designed to assess the flame-retardant performance of single wires and cables under controlled laboratory conditions. It provides stable flame generation, accurate sample positioning, and automated monitoring for repeatable and reliable results. The instrument is widely used in electrical, electronics, and appliance industries to ensure product compliance with international safety standards.

(7) Easy-to-operate controls for adjusting gas and airflow rates.

(8) Compact dimensions for laboratory integration (L × W × H: 60 × 45 × 156 cm).

Accessories

(1) Bunsen burner assembly with flame height adjustment.

(2) Adjustable test beam with 45° inclination.

(3) Gas and air flow control valves.

(4) Sample holder for wire/cable mounting.

(5) Safety protection components (emergency stop, flame shield).

(6) Instruction manual and calibration certificate.

Test Procedures

Install the test sample (wire or cable, 600 ± 25 mm) onto the sample holder.

Adjust the test beam to 45° inclination relative to the sample.

Set the flame height according to the standard or test protocol.

Connect and regulate the combustion gas (propane or LPG) and airflow rates.

Initiate the flame and begin the timer for the required exposure duration.

Observe the sample and record the combustion behavior according to applicable standards.

Remove the sample safely after the test and evaluate the flame-retardant performance.

Maintenance Information

(1) Regularly clean the burner tip and sample holder to prevent residue buildup.

(2) Inspect gas and air flow lines for leaks and proper operation.

(3) Ensure electrostatic spraying surface remains intact to prevent corrosion.

(4) Calibrate flame height and timing mechanisms periodically to maintain accuracy.

(5) Store the instrument in a dry, ventilated environment when not in use.

(6) Follow all safety guidelines when handling flammable gases and during testing.
