Sleeping Bag Flammability Tester – ASTM F1955
The Sleeping Bag Flammability Tester is designed to evaluate the flame resistance of sleeping bags, in compliance with ASTM F1955. The instrument can operate in either manual or automated test modes, depending on customer requirements. It ensures accurate assessment of sleepwear materials’ resistance to ignition and flame propagation, improving safety in outdoor, military, and industrial applications.
Applications
(1) Outdoor gear and camping equipment – sleeping bags for camping, trekking, and mountaineering.
(2) Military and defense equipment – flame-retardant sleeping bags used in field operations.
(3) Rescue and emergency shelters – fire-resistant sleeping materials for disaster relief or emergency evacuation.
(4) Industrial and safety textiles – flame-retardant blankets and insulated fabrics used in hazardous environments.
(5) Product testing laboratories – quality control and certification of flame-resistant textiles for consumer safety.
Standards
(1) ASTM F1955 – Standard Test Method for Flammability of Sleeping Bags.
(2) CPAI 75 – International Sleeping Bag Flammability Standard issued by the International Association of Industrial Fabrics.
(3) ISO 6941 – Textiles – Burning behavior of vertical specimens (for reference in material flammability testing).
(4) NFPA 701 – Standard Methods of Fire Tests for Flame-Resistant Fabrics (supplementary reference).

Result Evaluation
(1) T-time – Time measured from burning the first control line to the second line; if the flame extinguishes before the second line, the extinguishing time is recorded.
(2) D-damage distance – Length of material damaged between the first and second lines.
(3) Flame height can be adjusted via the rotor flow meter to ensure consistent test conditions.
Advantages
(1) Manual and automatic testing modes provide flexibility for different lab requirements.
(2) Stainless steel chamber with glass window ensures durability and clear observation of flame behavior.
(3) Adjustable flame height ensures consistent and repeatable test conditions.
(4) U-shaped sample frame maintains sample stability during testing.
(5) Compliant with international standards, supporting certification and quality control.
