Abstract
In the contemporary metrological sciences there are two main theories. The theory of measurement errors and the measurement uncertainty theory. Both of them were described in [1] with respect of the analysis of the thermographic measurements accuracy. However, the practical examples for the measurement errors and uncertainties estimation were not included in the abovementioned monograph. Therefore, the practical examples of error calculation were presented in [2]. The purpose of this paper is to show the exercises of estimation of the combined standard uncertainty and its components occurred in the non-contact temperature measurements made by means the infrared cameras. In this work the calculations conducted at the most common conditions existed in practical situations were presented. In each example the 95% coverage intervals were calculated. They enable the universal accuracy estimation in accordance with the guidelines of the international metrological organizations [3, 4]. This paper is also an extension of the material presented in works [5, 6].
