Measuring the Performance of Temperature Chambers in Accordance with IEC60068-3-5:2018

At the Standards and Calibration Laboratory (SCL), a method to measure the performance of temperature chamber was developed based on the international standard IEC 60068-3-5 – Environmental Testing – Part 3-5: (2018) Confirmation of the Performance of Temperature Chambers. A multi-channel temperature logger with platinum resistance thermometer sensors was used for the measurement. In this paper, details on the setup and procedure for the measurement of the achieved temperature, temperature fluctuation, temperature gradient, temperature variation in space and temperature rate of change of a chamber are provided. Examples of measurement results and the method for uncertainty evaluation are also presented.
