SGJ337 Pressure Conduction Thermal Resistance Tester

• SGJ337 Pressure Conduction Thermal Resistance Tester

  Instrument purpose:
  The pressure conduction thermal resistance test device (CCHR) is constructed under the conditions of heat insulation, heat production and quantitative heat value according to the standard test methods of thermal protection performance of NFPA 1971 and ASTM f1060 protective clothing fabrics under thermal surface contact.
  After the protective clothing fabric is close to the heating surface, if it is pressed on the skin to release} enough heat again, it will cause skin burns. To measure the energy transmitted from the protective fabric to the wearer, unified fabric exposure conditions and complex parameter analysis are required.
  ASTM f1060 test method is used to measure and calculate the thermal insulation performance of protective clothing fabrics close to a hot surface with a temperature up to 600F (316 ℃). CCHR fully complies with the standard. It includes a heating plate with accurate temperature control and test surface with uniform heat conduction, sample rack, movable calorimeter, pneumatic transmission tray and compressed air system, plus data acquisition and control system.
  Compliance with standards:
  NFPA 1971, ASTM f1060 thermal protection performance standard of protective clothing fabric under thermal surface contact, etc;
  Instrument characteristics:
  1. Evaluate potential skin burns caused by heat conduction after fabric press contact;
  2. Automatic or manual test operation;
  3. The range of pneumatic compression pressure borne by the sample ranges from 0.5psi to 8.0psi;
  4. The loading pressure of the sample is monitored in real time through an accurate gravity valve;
  5. The heating surface can be accurately heated up to 371 ℃± 1.5 ℃;
  6. The sample rack is electronically controlled to accurately control the exposure time of the heat source;
  7. During the test, the copper plate can make the heat conduction more uniform.
