제품특징

Thermetrics compact Radiant Protective Performance (RPP) Test Device measures and predicts the time to second degree burns following radiant heat exposure to composite fabric systems.
The RPP device includes a 5-bulb quartz infrared heat lamp assembly, a pneumatically actuated water-cooled shutter, two thermocouple inputs, software safety interlocks, and an integrated sensor cooling stand for improved test throughput, rates.
System includes PC laptop computer installed with ThermDAC data acquisition and control system, and automatic second degree burn determination.
During testing, our ThermDAC control software continuously records and displays a real-time graph of the average temperature rise, depicted as a curved line representing increasing temperatures as heat moves through the composite fabric materials to the sensor.
After the test is completed, the results are automatically compared to the Empirical Performance Curve (Stoll’s Curve), which predicts a second degree burn damage to human skin as a function of heat and time. The point of intersection between these two curves provides the composite fabric’s RHR/RPP rating.
