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.
