Abstract

In the paper a development of an accredited temperature calibration laboratory in the field of non-contact thermometry is presented. The laboratory was first accredited for calibration by comparison of contact thermometers and calibration baths and furnaces in the range from -55 °C to 1250 °C. It also became a holder of national standards for thermodynamic temperature thus providing the traceability of temperature in Slovenia. After a strong demand for calibration of non-contact thermometers was expressed by mostly export oriented industry in Slovenia, the laboratory has started a set of activities with an objective to establish a facility for calibration by comparison of radiance thermometers. These activities included besides a purchase of the equipment also an extensive training of experts, which have developed, written and implemented the procedures for evaluation and calibration of blackbody sources, and determined the best measurement capabilities with the existing equipment.
