Horizontal Combustion Tester

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)

IV. Compliance Standards

• ASTM D6413 (Vertical and horizontal flame propagation)
• ISO 6941 (Textile flame spread rate)
• NFPA 701 (Standard for flammability of draperies)
• GB/T 5455 (Chinese textile combustion standard)

V. Applications

1. Textile Manufacturing: Certifying fabrics for public buildings
2. Interior Design: Evaluating drapery fire resistance
3. Fire Safety Departments: Compliance testing for hotels/hospitals
4. R&D: Developing flame-retardant coatings

Standard Operation Workflow:

1. Sample Preparation: Cut to size, clamp horizontally
2. Calibration: Reference fabric validation
3. Testing: Ignite burner at specified height/duration
4. Analysis: Generate flame spread velocity curves
5. Cleaning: Automated soot extraction system

Safety Precautions:

• Fire-rated enclosure required (class A60)
• PPE mandatory (heat-resistant gloves, goggles)
• Fire extinguisher (Class B) must be on standby
