Design and Construction of a Prototype for Measuring the Thermal Conductivity of Insulating Materials, Plastics and Metals According to ASTM C177 with Staged Heating

The design of a better device for the measurement of thermal conductivity is described, which consists of systems such as: cooling system, heating system, cooling system, SCADA system, which for the measurement we will mix the advantages of stationary and transients, speeding up the measurement of this parameter achieved with stepped heating, this device specializes in the measurement of solid insulating materials, widely used in construction as cost reduction or alternative to the use of home heaters, samples can achieve weighing up to 12 kg, the ASTM C177-13 standard and those related to it were taken as a fundamental basis for the design of the device and the specimens to be measured, concluding that this design can perform measurements quickly, efficiently controlling the losses of the radiation and convection heat fluxes.
