Drapery Flammability Tester
I. Product Overview
TheDrapery Flammability Testeris a specialized instrument designed to evaluate the flame resistance of textiles and drapery materials in compliance with international fire safety standards. It simulates real-world fire scenarios to quantify ignition resistance, flame spread, and self-extinguishing properties.
- Type: Vertical/horizontal flame propagation tester
- Test Standards: NFPA 701, ASTM D6413, ISO 6941
- Flame Source: Propane gas burner (12mm nozzle)
- Sample Size: 610×1220mm (vertical) / 610×2440mm (horizontal)
- Key Metrics:
- Flame Spread Time (seconds)
- Char Length (mm)
- Afterflame/Afterglow Duration

IV. Compliance Standards
- NFPA 701 (Standard Methods for Fire Tests of Draperies)
- ASTM D6413 (Vertical Ignition Resistance)
- ISO 6941 (Textile flame propagation)
- BS 5852 (UK flammability standard)
V. Applications
- Textile Manufacturing:Certifying fabrics for public buildings
- Interior Design:Evaluating drapery fire resistance
- Fire Safety Departments:Compliance testing for hotels/hospitals
- R&D:Developing flame-retardant coatings
Standard Operation Workflow:
- Sample Preparation: Cut to size, clamp vertically/horizontally
- Calibration: Reference fabric validation
- Testing: Ignite burner at specified height/duration
- Analysis: Generate flame spread velocity curves
- 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
