RPP (Radiant Protective Performance) Device

• Device evaluates the potential for skin burns associated with a fabric's ability to block radiant heat penetration.
• Automatic or manual test operation.
• Two snap-on, snap-off sample assemblies for fast and easy test setup.
• Supports up to two copper disk calorimeter sensor assemblies.
• Integrated air-cooled sensor stand quickly prepares calorimeter sensor for next test.
• Water-cooled shutter is pneumatically actuated for precise exposure control.
• System includes Burn Algorithm to predict the time to second degree burn following exposure.
• Burn results shown as a real-time numerical and graphical display of sample performance compared to Stoll curve.
• Full system operating manual and one year limited warranty.

The RPP device uses a 5-bulb quartz infrared heat lamp assembly to provide a precisely controlled radiant heat source. During testing, ThermDAC control software will continuously record and display a real-time graph of the average temperature rise, depicted as a curved line representing higher and higher temperatures as heat penetrates through the composite fabric materials to the sensor. After the test is completed, the results are automatically compared to Stoll's curve, which represents the blister point of 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.

System includes PC laptop computer with ThermDAC data acquisition and control system, plus burn prediction algorithm.
