Özet:

Our country has a great importance in the world market in terms of the production of metal raw materials and end products, especially in the iron and steel industry. In order to realize an efficient and high quality production process, it is necessary to continuously monitor the Carbon (C) and Sulfur (S) concentrations of the material throughout the entire production process. During the marketing phase of the products in question, the material qualities must be reported by the conformity assessment bodies. At this stage, it is expected to increase the accuracy and reliability of the measurement results in the quality control tests of the products. For this purpose, the verification and validation of the analysis method which were employed should be carried out by the conformity assessment bodies. However, it is observed that there are different applications that fall outside the procedures described in the relevant international guidelines. In this study as an example to the best available techniques, method validation and uncertainty estimation studies were carried out for the total carbon (C) and total sulfur (S) analyses in metals and alloys following the procedures described in the standard of "General Requirements for the Competence of Test and Calibration Laboratories".
