NFPA 1971 TPP Thermal Protection Performance Tester For Textile
Protective Clothing
Thermal Protection Performance Tester Introduction:
Thermal Protection Performance Tester is suitable for textiles and
garments, petroleum chemical industry, labor protection and quality
supervision, inspection and other industries or establishments with
different requirements for protective clothing for thermal
protection performance test, for the development of flame-retardant
protective clothing in the production process, quality control and
flame retardant protective clothing for the use of thermal
protection performance test provides a reliable scientific basis.
Used for testing protective clothing, safety shoes, gloves, thermal
protective performance at the outer surface of the helmet. By
established under the effect of heat radiation source, testing the
thermal protective performance of materials.

Thermal Protection Performance Tester Feature:
1.Stainless steel frame structure, appearance, corrosion
resistance, easy to clean;
2.The heat source consists of: 1 set of radiation heat source and
two 45° convection heat. Radiant heat from the nine T-150 infrared
quartz lamp components. Convection heat lamp composed by two Meker
lamp.
3. Equipped with removable stainless steel protection plate; ensure
the safety and reliability of the testing process;
4.The basic components of the thermal protective performance
instrument are the sample holder assembly, fire-breathing head
radiant heat, water shutter sensors, data acquisition systems, fuel
control regulator, rotary gas meter;
5.Two 45-degree placed Meker burner;
6.Tube inner diameter is 38mm, the hole diameter is 5/16 inch,
providing 800-1200 Btu heat output burner ports is a metal mesh
structure, a valve at the bottom of the burner can be adjusted to
control the mixing ratio of air and gas;
7.9 T150 infrared quartz tube array, which provides heat flux of 13
kW/m2 ± 4 kW/m2;
8.With quartz infrared heat radiation, the total heat flux can be
set on 83kW/m2±2kW/m2 , by adjusting the Meker burner gas supply
Control System:

operating range is 0-100KW/m2, and the maximum range is 150%;
2.The response time of heat flow meter is less than 200ms, the
radiation rate is greater than 0.95, the output signal in working
range is greater than 5mv;
3.Equipped with a heat flux meter to show the real-time heat flux
value;
4.Testing protection thermal protection factor of TPP, display time
- temperature curve;
5.Rotameter can adjust combustion gas flow, the accuracy is ±2%,
range greater than 3 l/min;
6.A pointer gauges, intake pressure can be adjusted by the reducing
valve, the range of the reducing valve is 0-15psi;
7.Quarter turn plugs, combustible gas can be cut manually;
8.Sensor data acquisition system capable of recording the lowest
temperature of 150 ºC. The temperature acquisition system with a
resolution of 0.1C°, an accuracy of ± 0.75°C.
9.Data acquisition system for the automation of data collection
rate should be at least 10Hz, and provide cold junction
compensation for thermocouple measurements.
10.Equipped with computers and printers, with the standard test
software, standard test curve.
