ISO 6941 Textile Fabric Burning Behavior and Flame Spread Performance Test Chamber – BONAD Flammability Test Chamber
Standards:
- ISO 6941:2003: Measures flame spread properties of vertically oriented textile specimens.
- Scope: Validates flame spread time, ignition resistance, and post-combustion behavior under standardized conditions.
Applications:
- Materials Tested: Single or multi-component textiles (coated, quilted, multi-layer, sandwich composites).
- Industries: Apparel, automotive interiors, upholstery, industrial fabrics, firefighter gear, and protective clothing.
- Testing Focus: Vertical flame spread time, ignition resistance, and compliance with international fire safety regulations.
Features:
- Precision & Compliance
- Fully compliant with ISO 6941:2003, ensuring globally recognized test results.
- Automated ignition system with adjustable flame exposure (10s standard).
- Advanced Technology
- Imported High-Precision Instruments: Ensure repeatable and accurate measurements.
- Digital Flow Regulator: Enables precise flame control for consistent test conditions.
- User-Friendly Design
- Vertical specimen mounting with adjustable pins for secure positioning.
- Clear observation window for real-time monitoring of flame spread.
- Durability & Safety
- Flame-resistant chamber construction with heat-resistant glass.
- Automatic gas shut-off and safety interlocks for operator protection.
- Data Reporting
- Tracks critical parameters: flame spread time, ignition source details, ambient conditions (temperature, humidity), and specimen pretreatment.
Post-Test Reporting Requirements
- Compliance statement with ISO 6941:2003 and any deviations.
- Gas type, test date, ambient conditions (temperature/humidity).
- Specimen mounting method, pretreatment details, and exposed surface orientation.
- Ignition time, flame application method (surface/bottom edge), and results per ISO 6941:2003 Clause 10.1.3.
