Thermal and Flame Resistance Testing
topic
Thermal and flame resistance testing of coated textiles uses vertical flame test per ISO 15025, limiting oxygen index per ISO 4589, arc flash protection per ASTM F1959, and radiant heat resistance per ISO 6942 to characterise the flammability, char formation, and thermal protection performance of coated protective fabrics for fire-fighter, electrical worker, and industrial thermal hazard protection applications requiring defined burn injury prevention performance.
Role
Verifies that thermally protective coated fabrics meet the minimum protective performance required by standards for each thermal hazard application category, with flame and thermal resistance testing being mandatory for protective clothing certification and providing the technical evidence required for product liability management in high-consequence applications where inadequate thermal performance could cause severe burn injury to garment wearers.
