ASTM D4018, ISO 17492, NFPA 1971 TPP Thermal Protective Performance
Test Apparatus
Description:
TPP Thermal Protective 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.
It is also 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.
Standards:
NFPA 1971, Standard on Protective Ensembles for Structural Fire
Fighting and Proximity Fire Fighting
ASTM D4018, standard test method for thermal protective performance
of materials for clothing by open-flame method
GB 8965.1, Protective clothing—Flame-retardant protection- Part 1:
Flame-retardant protective clothing
ISO 17492, Clothing for protection against heat and
flame—Determination of heat transmission on exposure to both flame
and radiant heat
Features:
1. Stainless steel frame structure, appearance, and 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:
1. The domestic water-cooled heat flow meter, 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 0.1°C, 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.
