Horizontal Combustion Tester ISO 6941 Horizontal Burning Test Equipment
Product Overview
TheHorizontal Combustion Testeris a standardized instrument designed to evaluate the flame propagation characteristics of textiles, plastics, and composite materials under controlled horizontal flame exposure. It quantifies ignition resistance, flame spread rate, and self-extinguishing behavior in compliance with international fire safety standards.
Type: Horizontal flame propagation tester
Test Standards: ASTM D6413. ISO 6941. NFPA 701
Key Metrics:
Flame Spread Time (seconds)
Char Length (mm)
Afterflame Duration (seconds)
Sample Size: 610×1220mm (horizontal clamping)
