Flammability Tester

The Thermal Protective Performance Tester is designed to evaluate the thermal protection performance of protective clothing across industries such as textiles, petrochemical, occupational safety, and quality supervision. It provides a scientific and reliable basis for the development, quality control, and performance verification of flame-resistant protective garments.

The tester applies controlled heat flux from radiation and convection sources to protective materials or garments, measuring the thermal protective performance and generating time-temperature response data.

Applications

(1) Testing the thermal protection performance of flame-resistant protective clothing for firefighters, industrial workers, and laboratory personnel.

(2) Evaluating heat protection of safety shoes, gloves, helmets, and other personal protective equipment (PPE) surfaces.

(3) Quality control during production of thermal protective garments.

(4) Research and development of advanced flame-retardant textile materials.

(5) Verification testing in certification laboratories and compliance assessment for occupational safety standards.

(6) Performance testing under controlled radiant heat flux to determine TPP (Thermal Protective Performance) values and heat exposure response curves.
