Flammability Tester

The Textile Flammability Tester (Large 45°) is designed to evaluate the flammability characteristics of textile materials at a 45° angle. It allows determination of afterflame time, afterglow time, damaged length, damaged area, and the number of flame contacts required for specified burning conditions. This tester is suitable for textile research, quality control, and compliance testing according to national and international flammability standards.

Application

The Textile Flammability Tester (Large 45°) is used to ignite fabrics at a 45° angle for two methods:

Method A: Determines the damaged area and damaged length of textiles and similar materials.

Method B: Determines the number of flame contacts required when textiles melt under heat and burn to a specified length.

It is widely applied in textile manufacturing, laboratories, and R&D institutions for flammability testing and product certification.

Standards

The Textile Flammability Tester (Large 45°) complies with the following standards:

(1) GB/T 14645-2014 — Method A and Method B for textile flammability

(2) Other related national and international textile flammability testing standards

Test Principle

The Textile Flammability Tester (Large 45°) ignites the specimen at a 45° angle in a controlled combustion chamber. The flame height and position are precisely adjusted using a rotor flowmeter. During testing, the specimen is supported by dedicated clamps or coils depending on the method used. After ignition, the afterflame and afterglow times are recorded, and the extent of damage is measured to evaluate the material’s flammability performance.
