45°Test Determination of Flame Spread Rate

The LS-GBT14644-2 45° Test Determination of Flame Spread Rate is a professional testing instrument developed by LISUN for evaluating the combustion intensity of textile fabrics. It follows the core test logic: the test specimen is placed at a 45° angle, ignited for 1 second, and the time required for the specimen to burn with a flame over a specified distance is measured. This data serves as a key metric to assess the fabric’s flammability, providing accurate and reliable support for the flame retardant performance verification of textile products and helping them meet domestic and international compliance requirements.
