Safety Helmet Flammability Tester

The Safety Helmet Flammability Tester is designed to evaluate the flame-retardant performance of safety helmets when exposed to a standardized open flame. The instrument provides a controlled and repeatable test environment to determine afterflame time and afterglow time, ensuring that helmets meet fire safety requirements under relevant national and international standards. With a high degree of automation and precise timing control, it is widely used by helmet manufacturers, quality inspection institutions, and construction engineering testing laboratories.

Application

The tester is suitable for flame retardancy assessment of head protection products exposed to fire or high-temperature environments. Typical application scenarios and tested products include:

(1) Industrial Safety Helmets – construction helmets, mining helmets, oil and gas industry helmets.

(2) Electrical Safety Helmets – insulating helmets used for power distribution, substations, and electrical maintenance.

(3) Rescue and Emergency Helmets – firefighting helmets, emergency rescue helmets, disaster response helmets.

(4) Special Protective Helmets – metallurgical helmets, chemical industry helmets, welding and thermal operation helmets.

(5) Helmet Materials and Components – helmet shells, brim materials, suspension systems, and flame-retardant coatings.

(6) Quality Control and Certification Testing – routine factory inspection, third-party certification, and type testing for compliance verification.
