Applications:

The Pressure Thermal Resistance Tester is designed according to the thermal protective performance test methods specified in NFPA 1971 and ASTM F1060 for evaluating the thermal protection performance of protective clothing fabrics under contact with heated surfaces.

When protective clothing fabrics are pressed against a heated surface, the transferred heat may be released toward the wearer’s skin under pressure, causing potential burn injuries if sufficient heat energy is transmitted. To measure the amount of energy transferred through protective fabrics to the wearer, standardized fabric exposure conditions and precise parameter analysis are required.

The ASTM F1060 test method is used to measure and calculate the thermal insulation performance of protective clothing fabrics when placed in contact with a heated surface at temperatures up to 600°F (316°C). The tester fully complies with this standard and integrates a precisely temperature-controlled heating plate, a uniformly heat-conductive test surface, specimen holder, movable calorimeter, pneumatic transmission tray, compressed air system, and data acquisition and control system.

Applicable Standards

NFPA 1971 — Standard on protective clothing and equipment for structural fire fighting and proximity fire fighting
ASTM F1060 — Standard Test Method for Thermal Protective Performance of Materials for Clothing When Exposed to Contact with a Heated Surface

Instrument Features

Evaluates the potential skin burn risk caused by heat transfer when protective fabrics are pressed against heated surfaces.
Supports both automatic and manual testing modes to meet different laboratory requirements.
The pneumatic compression pressure applied to the specimen ranges from 0.5 psi to 8.0 psi.
The pressure applied to the specimen is monitored in real time through a precision gravity valve system, ensuring accurate pressure control during testing.
The heating surface can be accurately heated up to 371°C ± 1.5°C, providing stable and reliable thermal exposure conditions.
The specimen holder is electronically controlled to precisely regulate the exposure time of the sample to the heat source.
During testing, the copper plate provides uniform heat conduction, ensuring consistent heat transfer across the specimen surface and improving test accuracy.
