Abstract	One of the main criteria demonstrating the competence of a calibration laboratory is successful participation in inter-laboratory comparisons. Real capability of the laboratory including claimed uncertainties could be demonstrated based on the results of comparisons, evaluated either through $$E_{\mathrm{n}}$$ -criteria or other acceptable measures. As a number of accredited laboratories with scopes covering calibration services in the field of thermometry have been increasing, the demand for organization of inter-laboratory comparisons with participation of accredited laboratories occurs. Based on this fact, a national inter-laboratory comparison of thermocouple calibrations in the temperature range from $$100\,^{\circ }\hbox {C}$$ to $$1000\,^{\circ }\hbox {C}$$ in the field of temperature was launched by TUBITAK UME in 2011. The purpose of the inter-laboratory comparison was to compare the results of the participating laboratories during calibration of the thermocouples in the range from $$100\,^{\circ }\hbox {C}$$ to $$1000\,^{\circ }\hbox {C}$$ . Three type S thermocouples were constructed and calibrated by TUBITAK UME which is the pilot laboratory of the comparison. It was recommended that the participants use their standard procedure for the calibration of thermocouples and follow the instructions of comparison protocol during the calibration. The inter-laboratory comparison was carried out among eleven national accredited laboratories. In this paper, the temperature differences obtained by participating laboratories with associated uncertainties of the results and $$E_{\mathrm{n}}$$ values will be presented. The metrological equivalence of all laboratories was demonstrated, with all $$\|E_{\mathrm{n}}\|$$ values being less than 1.0.
