Features and Test Methods of TPP Thermal Protection Performa

Author: Date :2021-10-08 Views: order
The TPP Thermal Protection Performance Tester exposes protective materials to flame to detect the amount of heat passing through. It is used to determine the fire resistance of textiles, fire protection products and other materials. A horizontally fixed sample is exposed to a propane burner flame with an impact heat flow density of 80 kW/m2 and the heat passing through the specimen is measured with a calorimeter. The time required to rise 12°C and 24°C in the calorimeter, respectively, was measured. The heat transfer index is the average of the results of three specimens. The device consists of a burner, a cover plate, and a calorimeter with a specimen holder.
 
The TPP thermal protection performance tester device is controlled by a software-controlled pneumatic unit. The software contains the calculation and evaluation methods specified by the standard. This software also controls the propane gas delivery switch. For safety reasons, the burner is also equipped with an electronic pilot flame safety.

 

TPP Thermal Protection Performance Tester Test Method

 
Place a heat source on one side of the sample being tested and a copper calorimeter on the other side. Start the test, push and pull the sample clip into place, and when the value of the sensor reaches the human secondary burn tolerance limit (sensor temperature rises 35℃~40℃), remove the sample clip from above the heat source. From the point where the reaction curve and the human tissue tolerance curve intersect, the time leading to second-degree burns is read out precisely to 0.1 second.
