CCHR (Conductive Compressive Heat Resistance) Test Device
The Conductive and Compressive Heat Resistance (CCHR) device evaluates the potential for skin burns resulting from a fabric’s conductive properties under compression.
Protective clothing materials that are exposed to heated surfaces can absorb and re-emit enough thermal energy to cause serious burn injuries when the composite fabric material is compressed against the skin. Measuring the amount of energy transferred by a protective fabric via thermal conduction to the wearer requires specific exposure conditions and complex analysis—parameters that the CCHR device was developed to isolate, reproduce, and quantify.
TEST STANDARDS: ASTM F1060, NFPA 1971
