Thermal Protective Performance Tester

What is The Thermal Protective Performance Tester？

This test applies to the thermal protective performance of single or multilayer materials, used for evaluating the thermal protective materials of personnel exposed to convective and radiant heat hazards. It is not applicable to materials that are non-flame-retardant, or those that melt, drip, or degrade when exposed to high temperatures

Thermal Protective Performance Tester (TPP) is the latest product in the ZONSKY Fire Equipment Testing Equipment series

Compliance：GA10-2014/NFPA 1971-2017/ISO 12749

Computer control interface mode: computer + professional software control, guided operation, convenient, safe and reliable operation, all cumbersome procedures and calculations have been integrated into the computer, the response speed is very fast and the operation is convenient.

During the control test, the test data can be viewed in real time, and automatic data calculation, collection and processing, data storage and output of test reports and measurement results can be realized.

The heat insulation shield isolates the heat source and adopts automatic control, which is controlled by a computer program. After the heat insulation shield is removed, the sample is exposed to the center point above the heat source and automatically starts to record data.

Design Principle

1. The flame retardant material sample is placed horizontally and a certain distance is placed from the convection/radiation mixed heat source. When the heat transmitted is equal to the second-degree burns caused by human tissue, the exposure time is recorded. According to the different placement positions of the sample and the test sensor, direct contact is used to simulate the contact and wearing of flame retardant protective clothing with the body, and a spacing of 6.5mm is used to simulate the situation where there is a certain space between the flame retardant protective clothing and the body.

2.The product of the time corresponding to the intersection of the heat transfer reaction curve measured by the copper calorimetric sensor and the Stoll curve and the total heat flux exposed to the material (i.e., cumulative energy) is obtained to obtain the thermal protection performance value (TPP) of the sample;

3.Thermal protection performance value (TPP): In the process of testing thermal protection materials, the cumulative energy is determined by the intersection of the heat transfer reaction curve of the material measured over the cumulative time and the Stoll curve;

3.Stoll curve: A standard curve used to predict the relationship between the time and heat energy to reach the second degree burn. Energy values above the Stoll curve are more likely to cause second-degree burns, while energy values below the Stoll curve are less likely to cause second-degree burns.
