  • Evaluates the potential for skin burns that may be associated with a fabric's stored thermal energy. The Stored Energy Test Device fully complies with ASTM F2731 Standard Test Method for Measuring the Transmitted and Stored Energy of Firefighter Protective Clothing Systems.
  • Radiant panel heat source (adjustable from 0-0.25 cal/cm2) produces radiant energy matching the spectral density of a structural fire.
  • Water-cooled sample carriage and copper calorimeter exposure sensor, electronically actuated for precise control of exposure time over the heat source.
  • Pneumatically controlled compression system applies 1 PSI pressure load to sample via a low conductivity mandrel.
  • 6"x6" (15x15cm) sample size. Spacers of various thicknesses are provided for when minimal sample edge compression is desired.
  • Automatic or manual test operation.
  • System includes integrated Burn Model to predict the severity of skin damage. Results shown as a real-time numerical and graphical display of the epidermis-dermis layer interface temperature and burn integral Omega.

Firefighter protective clothing materials exposed to moderate levels of radiant heating can cause serious burn injuries when compressed against the skin. The Stored Energy Test (SET) Device provides a standardized procedure and controlled radiant heat conditions to generate repeatable measurements of heat storage and transfer in protective fabric materials. These measurements allow for rapid characterizing and ranking of materials, and, through the Stored Energy Test Device's integrated burn model software, provides a prediction of possible burn injury.
