Thermal Protective Performance (TPP) 

Will your material system protect against a 2nd degree burn?  The TPP (Thermal Protective Performance) device, also known as a HTP (Heat Transfer Performance) device was developed to measure the time elapsed for convective and radiant heat to penetrate through a protective composite fabric system - resulting in damage to human skin. 

TEST STANDARDS:   ISO 17492, ASTM F2700 (D4108), ASTM F2703, CAN/CGSB 155.20, NFPA 1971, 1977, and 2112 

Radiant Protective Performance (RPP)

Thermetrics compact Radiant Protective Performance (RPP) Test Device measures and predicts the time to second degree burns following radiant heat exposure to composite fabric systems.

TEST STANDARDS:   ASTM F1939, ASTM F2702, NFPA 1971, NFPA 2112.

Stored Energy Tester (SET) 

The Stored Energy Test (SET) device evaluates the potential for skin burns that may be associated with a fabric’s stored thermal energy.

Firefighter protective clothing materials exposed to moderate levels of radiant heat can cause serious burn injuries when compressed against the skin. The amount of energy stored in a protective fabric and transferred to the wearer requires specific exposure conditions and complex analysis - parameters that the SET device was developed to isolate, reproduce, and quantify.

TEST STANDARD:   ASTM F2731 

Conductive Compressive Heat Resistance (CCHR)

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

Copper Calorimeters - Accessories

copper calorimeter sensors for the TPP, RPP, CCHR, and other thermal protection test devices are key to accurate energy exposure predictions.

A copper calorimeter sensor measures the temperature rise in a thermally insulated slug to determine heat transfer rates for a wide range of applications, including radiant and convective heat flux.
