Blanket Flammability Tester (ASTM D4151)
The Blanket Flammability Tester is a laboratory instrument designed to evaluate the flame retardancy and surface flame spread performance of blanket fabrics. Using a standardized flame for a specified duration, it allows observation of the burning, damage, or discoloration of test papers, enabling classification of fabric flammability according to ASTM D4151.
Application Scenarios
(1) Textile manufacturers: testing wool, cotton, polyester, and blended blanket fabrics for flame resistance
(2) Bedding production: assessing safety performance of blankets, throws, and bedspreads
(3) Quality control laboratories: routine inspection of blanket fabric batches to ensure compliance with fire safety standards
(4) Research and development: developing flame-retardant treatments for blankets, quilts, and bedding textiles
(5) Educational institutions: teaching textile flammability testing and fire safety evaluation
(6) Comparative evaluation: assessing different fabric treatments, fiber types, or production batches for flame retardancy
Compliance Standards
(1) ASTM D4151 — Standard Test Method for Flame-Resistant Blankets
(2) ISO 6941 — Textiles — Determination of burning behavior of small specimens of fabrics
(3) BS 5438 — Method for assessing flame spread on blanket fabrics
(4) Relevant fire safety and flammability test standards for bedding and textile products
