Touch Screen TPP Thermal Radiant Performance Tester GT-RC02A
Application
This Touch Screen TPP Thermal Protection Tester is used for testing the thermal protective performance (TPP) value and performing thermal protective evaluation (TPE) of flame-retardant fabric products, including flame-retardant protective clothing, fire suits, fire boots and gloves, under exposure to radiant and convective heat sources.
Principle
Under exposure to a specified heat flux, the time to second-degree burns is derived from the intersection point of the response curve (temperature rise curve of the calorimetric sensor) and the human tissue tolerance curve (Stoll curve). The higher the product of the heat flux level and the time to second-degree burns, the stronger the thermal protective performance of the fabric.
Thermal Protection Tester
NFPA 1971 TPP Test Device
It is suitable for testing the thermal protection performance of single-layer or multi-layer materials, and for evaluating thermal protection materials for workers exposed to convective and radiant heat hazards.
As the test is being run, the tracing is compared with a second curve, called the Stoll's curve, which shows the blister point of human skin as a function of heat and time. The point of intersection between these two curves is the actual TPP rating. For the purpose of measuring actual time to burn, the TPP rating is divided in half to determine the number of seconds until human tissue reaches the second-degree burn point. Thus, the NFPA minimum requirement of a TPP rating of 35 equates to 17 ½ seconds until second-degree burns occur in a flashover situation.
