Drapery Flammability Tester

The Drapery Flammability Tester evaluates textile and drapery flame resistance per NFPA 701. ASTM D6413. and ISO 6941. It uses a propane burner (12mm nozzle) to test vertical (610×1220mm) or horizontal (610×2440mm) samples, measuring flame spread time (s), char length (mm), and afterflame/afterglow duration to assess ignition resistance and self-extinguishing properties.

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

Standards

NFPA 701: Standard Methods of Fire Tests for Flame Propagation of Textiles and Films

ASTM D6413: Standard Test Method for Flame Resistance of Textiles (Vertical Test)

ISO 6941: Textile Fabrics - Burning Behaviour - Measurement of Flame Spread Properties of Vertically Oriented Specimens

BS 5852: Fire Tests on Materials and Products, General Guidance for the Testing of Non-Metallic Materials
