ISO 5657 Building Materials Ignitability Flammability Tester
SL-FL56 Building Material Ignition Performance Tester
Machine Introduction
This tester evaluates the flammability of materials, composites, or components with thickness ≤70mm under specified thermal radiation conditions. Ideal for assessing:
- Wall and ceiling lining materials
- Flooring systems
- Exterior cladding
- Thermal insulation materials for air ducts
The test accurately simulates fire scenarios, distinguishing between easily ignitable materials and fire-resistant options to assess real-world fire risks.
Test Standards
Compliant with ISO 5657 international standard.
Machine Features
- Advanced Control System: PLC programming with computer interface, 16-bit high-precision board for 1% accuracy
- User-Friendly Interface: Labview-developed software with Windows XP compatibility and intuitive operation
- Precision Gas System: Propane/air supply with mass flowmeter control for consistent ignition flame
- Environmental Control: Specialized enclosure maintains air velocity ≤0.2 m/s while safely removing smoke
