The Vertical Flame Test Chamber is designed to measure the vertical flame spread of textiles, fabrics, and resilient filling materials. It is widely used for children's sleepwear, upholstery, household fabrics, and other materials requiring fire safety assessment. The chamber provides precise, controlled flame exposure, ensuring compliance with international and national flammability standards.
Application:
The vertical burning of textiles is suitable for all types of fabrics and their products. Test method applicable to the burning performance of the bottom edge of the vertical textile specified in GB5455-2014 standard.
