I. Product Overview
The Horizontal Combustion Tester is 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)
