Flame Spread Index Tester，ASTM E648 Flame propagation of carpet materials

The Flame Spread Index Tester is designed to evaluate the flame propagation characteristics of wall and ceiling lining materials. You can measure the material’s flame spread index (FSI) by exposing samples to a controlled tubular burner with a heat output of 530 J/s and monitoring the flame development over time. This tester allows you to assess fire performance accurately according to international and national standards, providing critical data for building safety, material development, and regulatory compliance.

Application

You can apply this tester in the following scenarios:

Building materials evaluation: Assess the flame spread index of wall and ceiling lining materials.

Plastic material testing: Determine vertical and horizontal flame propagation for polymer materials.

Fire safety compliance: Evaluate materials for civil, railway, and aerospace interior standards.

Quality control: Monitor production materials to ensure consistent fire performance.

Compatible test components: Tubular burner, quartz heaters, T-shaped burner, sample holders, thermocouples, and integrated computer data acquisition system.

Test Procedures

Install the sample in the combustion chamber using the appropriate sample holder.

Connect the G112 test gas supply.

Start the quartz heaters and T-shaped burner, providing thermal radiation and flame exposure.

Adjust heater power automatically according to the test schedule:

First 2 min 45 s: initial burner exposure at 530 J/s

At 2:45 min: increase total heater power to 1800 W

At 5 min: reduce power to 1500 W and maintain until test end

Record flame propagation, temperature, and FSI using the thermocouple and data acquisition system.

Total test duration is 20 minutes. Upon completion, safely remove the sample and review results.

Maintenance Information

Regularly clean the combustion chamber and burners to ensure consistent heat flux.

Calibrate thermocouples and power output control systems periodically.

Inspect sample holders and chamber integrity before each test.

Ensure gas supply is stable and leak-free.

Maintain ambient temperature between 10–35°C for consistent testing conditions.
