Issues with regard to the design, correction of data, and performance are dealt with for a cylindrical test heater prepared by inserting an electric cartridge heater into a hollow cylinder. The first part of the study presents a quantitative rule for the design of a test heater providing the most uniform boundary condition for heat transfer experiments. The second part investigates the effect of inactive zones in existence in the inserted cartridge heater on temperature and heat flux distributions based on conduction analysis. Finally, the problem of uneven heating generated by the cartridge heater is treated in the third part of this study. A method is proposed to detect the degree of uneven heating, and formulas are derived to assess its influence to the boundary condition of the test cylinder during a heat transfer experiment.
