The Helmet Flame Resistance Test Device, in accordance with NFPA 1971, is designed to evaluate the flame resistance performance of a protective helmet exposed to a Bunsen burner flame, radiant heat source, or both. Features • The Flame Resistance Tester consists of a test chamber, radiant heat source, Bunsen burner, gas supply system, heat flux meter, flame calibration device, and control system. • The heating elements of the radiant heat source are stainless steel rods, which can provide radiant heat up to 10kw/m2. • The heating elements are controlled by the PID controller, which with a resolution of o.1 degrees. • Equips with pneumatic heat insulation shield, automatic remove when the test starts. • Provides water cooling heat flux meter, measurement range up to 50 kw/m2, resolution of 0.1 kw/m2, with the self-cooling device. • Provides standard Bunsen burner, which meets NFPA 1971 requirements, flame temperature at the range of 1100 to 1300 degrees. • The gas supply system includes gas regulator, valves, spark ignitor, and float meters. • The flame calibration device, equips K type thermocouples, with a resolution of 0.1 degrees, and digitally displays the flame temperature. • The time recorder, resolution of 0.1 seconds, records the flame application time, and after flame time. • The metallic dummy head, complies with NFPA 1971, the position can be adjusted in the test chamber. • Windows based software, with the calibration functions.
